tory mucosa and skin stimulating effect on the bleaching effect of corrosion and articles, in general, use chlorine to kill the virus can be 1000 mg per liter, for 30 minutes. But the disinfection process, organic compounds react easily with chlorinated organic compounds, resulting in iodine preparations, cause of poisoning is often too high concentration or too long. Poisoning plot common gastrointestinal inflammation and mucus, diarrhea, and various degrees of death. Resulting decline in egg production of laying hens. There's at some of the data, with 0.1% potassium permanganate to chicken water, resulting in the oral cavity and upper gastrointestinal mucosa to corrosion, often resulting in the death of more chickens.
2. Brood care and use of apparatus for full and complete cleansing and disinfection.
(4) wet dirt, compacted hardened, poor bedding must be promptly replaced, or add fresh, dry, soft new bedding to cover.
2. Note that the ventilation must be kept well ventilated to eliminate the foul air, the ducks get fresh air and enough oxygen, feel comfortable in order to maintain health and normal metabolism, to promote the growth of good balance. To avoid thieves abrupt and sharp wind and temperature changes in the invasion.
(1) ducklings feed. Requirements easier to digest, nutritious; nutritional deficiency, dull hair,
(1) line feeding per square meter. 1 week 40 ~ 50; 2 weeks 20 to 25; 3 weeks of age 10 to 15.
③ Caesar feed pellets when the foot pieces and powder, leading to waste and feed intake of less than ducks;
(1) attention to ventilation ducklings metabolism, need to keep a lot of fresh oxygen inhalation emit large amounts of carbon dioxide and water vapor, and duck manure and bedding, etc. will produce large amounts of ammonia decomposition strong brood homes ventilation, to ensure indoor air fresh and dry.
2. Male and female ratio due at the beginning of egg production, each 100 can be used with 18 duck drake, which is to maintain a good egg fertilization rate is important, but not more than 20 drake, drake's because life and strong, too much to enhance the drake drake or disrupt the new order of ducks, you need to immediately remove excess drake. If all the drake is healthy and energetic, each with 16 100 duck drake is sufficient.
2. By feeding the appropriate salt
while adding 3% glucose drinking water or water-soluble electrolyte multidimensional.
(4) control the water level. Water apparatus 1.5 to 2 cm deep water, if too deep ducklings into wet hair and after exposure to cold causes a cold.
restricted feeding methods must note the following.
4. Amount of poultry feed a common feature of the sand is no teeth grinding through the sand stomach muscle food. Therefore, starting from the first 6 weeks of age, should be provided to the duck insoluble, particle size suitable gravel. Gravel should be thicker, but not greater than 0.5 cm in diameter, the amount of 100 ducks per week plus 500 grams, the stadium does not need to feed grit duck duck because ducks can feed to the playground in the sand to meet own needs.
(2) incubation period of feeding. Duck the quality is good or bad, (Ⅰ) is directly related to the number of qualified eggs (Ⅱ) Duck meat growth rate and quality.
5. Reasonable density
7. Light
(1) must be well ventilated to eliminate moisture laying shed.
(6) in the duck pre-open period of time, need to gradually increase the amount of feeding, (140-160 days) is generally increased by 2 times per week or 3 times, each increase of 1 per 100 ducks kg; to the beginning of egg production, the need to daily feeding, and greater increase in feeding volume; to duck egg production amounted to about 5% should be taken ad libitum. This will not only supply the adequate nutrition to stimulate egg production, but also good control of their weight and minimize stress.
duck reproductive performance include
1. Good housing equipment maintenance
(2) ground brood. Empty homes 2 to 3 days ventilated and dry; dried with 3 - 5% of the fire
feeding times: 0 ~ 3 days stand-by feed within the feed pan;
(4) weighing feed to be accurate, the accuracy of the amount of feed fed; Duck weighed regularly every 1,000 ducks usually weighing a sample of 50, to be randomly selected, weighed to be accurate, but must be In the non-feeding feeding on or before the weigh in, that is unified with the fasting body weight measured.
(a) General feeding and management
3. To maintain high fertilization rate requirements drake strong physique, ###### organs healthy, ######ually active, good quality semen, sperm motility high to have high fertility rates. Drake duck began to brood than 1 to 2 months early, to make Drake the duck egg has reached ######ual maturity before to improve the rate of egg fertilization. Incubation period, the public, the best duck cluster feeding (people want to put a small amount of duck drake drake with growth). Early ######ual maturity, not to the breeding of the drake water as little as possible to reduce the leisure among drake, the formation of Epi; 20 days before mating, the drake duck release group, this time should be more water activities less closed farming, to create conditions to facilitate their ######ually active, increasing the effective breeding number. Well-managed species of ducks, the egg, the fertilization rate should exceed 90% of hatching eggs, hatching eggs should be incubated more than 80%.
density is too large, ducks crowding, disturbance activities, feed, water unevenly, affecting growth and development, domestic ducks in the uniformity is poor, and could easily lead to E. coli, the spread of infectious diseases serosal go far, Amoy death rate increased. Density is too small and difficult to supply in temperature, low utilization of premises equipment, production costs are higher.
③ feeding amount is accurate, said the material exactly
15 ~ 21 days 22 ~ 19 ℃;
① control ducks appropriate density and group size; each duck at least to ensure the discounted area of 0.30 m2 and 0.30 square meters of playground area; each group of 300 is appropriate.
bred ducks feeding
2 of disinfection procedures and full understanding of all out
(3) drinking water appliance choices. General choice of drinking water vacuum apparatus, Pula Song style, tank-type and so on. Labor-intensive vacuum drinking, sanitation is poor, multi-purpose early brood; Pula Song conservation of drinking water, save manpower, discounted humidity is small, not easy to wash, health is poor; sink waste of drinking water, humidity, scrub convenience, more health
density should be based on day-old ducklings, seasonal and environmental conditions such as flexible.
(1) the influence of temperature on the ducklings. Suitable temperature, the ducklings water, feed, rest and other activities normal growth and development of fast. Low temperature, the ducklings tend to heat, squeeze each other get together, reduced activity, drinking water, feed intake decreased, prone to diarrhea and respira
tory tract disease, also cause compression injury, metabolic disruption, growth slowly. Sherwin increase in time. At high temperature, away from heat, affect the normal metabolism of reduced appetite,
imitation christian louboutin shoes, decreased resistance to disease.
3. When fed on ground litter control required concrete floor, most of the ground should be dry, bedding uniform thickness. The best way to spread bedding with a throw materials, and daily to keep litter dry and clean for the duck rest sleep. Good ventilation, drainage and placement of drinking fountains and other litter and ground can be kept dry. The best is a sand playground, and a certain slope, so that ruled out the excess water out, keep the venue dry. Duck does not necessarily need to swim, but water the face of high heat and sunstroke duck's egg, the fertilization rate is certainly helpful, and can save land, water utilization, so you can make full use of the water feeding species by breeding ducks.
6. Ventilation
② spill spreading material feed the ducks when the region can not lead to feed waste and feed intake of less than ducks;
kinds of feeding and management drake
(1) incubation of the duck's diet should be nutritionally complete pellets full price, especially the limiting amino acids and vitamins essential, therefore, not always free to change its feed formula,
(2) fed on the ground per square meter. 1 week 20 to 25; 2 weeks 10 to 15; 3 weeks of age 6 to 10.
disinfected with lime
④ not be used for spreading material powder feeding.
Whatever
3. Standard weight of ducks bred
4. Before the ducklings arrived, 2 hours in advance will be discounted water into the ground or the bed surface temperature,
1. Appropriate weight to weight control drake overweight, the fertilization rate of eggs which will produce a negative impact, through back-feeding of the restrictions, drake proper weight control. Usually limited drake to ad libitum feeding in several duck eggs have been produced after the original, that is scheduled to open in the middle of (the duck egg production rate of 15%) of the first 2 weeks (At this point duck egg production rate of 5%) onwards. This can well prevent the drake overweight but does not prevent egg fertilization rate.
1. Homes from the breeding species to adapt homes to begin laying duck at least 2 weeks, should be moved to the back-care kind of duck egg production, so that there is a duck and its management to adapt to new environmental regulations in the process, and the limit gradually to increase the amount of feed fed, and slowly converted to free feed.

(6) Other considerations
5. Breeding ducks lighting control
3. Prevent feather pecking and duck eggs
feeding by limiting the means to achieve the purpose of weight control, requiring up to standard weight. The result of feed restriction must be sampled to determine the weight and standard contrast. Weighing must be fasting at the same time, because the table is a list of standard varieties fasting weight. Weight measurement should be from the 4th week, once weekly weighing, until the opening production. Weighing the specific sampling method is: first female ducks were randomly selected 5% and 5% of Drake were weighing the total weight, calculate the average; then this part of the duck's body weight by only called out one; if the average particularly high or particularly low, you need to increase the sample size of 10% for the group, and then measured by only one weight. The public and the duck with its breed standard weight averages were compared, and if the same or very close to, the amount of normal feeding; if they are different, the amount fed should be changed accordingly; If the sample weight of individual differences in a large duck, then the groups of poor uniformity, to improve the feeding method, for example, increase the feeding equipment, changing feeding time, feeding and other clustering, while the weak residual duck out.
discounted air should be well ventilated and no invasion of thieves; summer doing summer cooling, to reduce heat stress; winter,
tembea mbt, pay attention to cold, control light, increase the exposure time from the beginning to the end of this period of time can not be reduced egg illumination time ; strict implementation of vaccination program, improve health and quarantine disinfection; to keep quiet and make all records to ensure that the duck is in perfect condition and comfortable to play the best reproductive performance
(4) homology group. Size according to the weight, the individual strength of the duck cluster, and note the following points:
8 ~ 14 days old feed once every 3 hours;
① According to the weight and uniformity,
She has not a virgin, and timely by the weight of the different duck adjusted to the appropriate medium and small circles to the field; This work is bad when the body weight and uniformity of the emergency measures, it is best to avoid;
ducklings after hatching, the brood in the dry store room and through the transport, ducklings will be significant loss of body water, water loss will seriously affect the absorption of yolk material, affect the health and growth. Therefore, the brooding young hires need to maintain the initial high relative humidity (60% to 70%). With the increase of age ducklings, weight gain, increased water intake, increased respiration, increased excretion, and you should try to reduce the relative humidity of brood care (50% -55%), to reduce the incidence of the disease . Avoid high temperature and high humidity or low humidity of the culture environment.
(1) illumination time. 1 day, 24 hours light; 2 to 7 days 1 hour less per day; 8 to 9 days, 2 hours less per day; 10 days after the night with light, in order to see the feed, water, appropriate .
4 ~ 7 days old feeding once every 2 hours;
(1) after drinking the water first to open food. Ducklings first meconium help to promote water discharges, increase appetite, and prevent dehydration and to promote intra-abdominal ducklings yolk absorption. Hatched ducklings should be 12 to 24 hours of times, water 2 to 3 hours before opening food.
physical characteristics of breeding ducks
Tim ground feed fed less, eat with Tim. After 3 days, you can use the trough or bucket feeding
egg boxes and bedding to keep in good condition need to pay attention to make the following points:
Therefore, keep a good duck meat duck production is a key basis for work. Duck in the incubation period, the organ system into the strong developmental stages, and gradually improve and become more sophisticated. Thus, this phase of the muscular system, skeletal system, reproductive system can lay the foundation, laying performance is directly related to the level of the future. Incubation period of relative weight gain of ducks decreased, but the absolute growth increase. Therefore, the performance of appetite, improve digestion, activity and strong. The purpose of breeding duck is not the pursuit of them to increase the number of weight, but to ensure that the premise of normal weight, kind of laying ducks will have a good performance, high egg production, egg material, feed conversion rate, the commodities on behalf of the Ducklings fattening effect. The main points of breeding ducks bred limit is raised.
limit.
① lead pellets dissolve the wet ground, causing the actual feed intake of waste and lack of ducks;
② early clustering.
(2) light intensity. 0 to 3 days old, 5.4 watt per square meter; 4 to 21 days of 2.7 watts per square meter.
The specific method of feeding
④ According to weigh the results carefully careful feeding amount approved for the next week.
3. A time limit for material
a sterilization problems and solutions:
; ;
the duck body and genital stage is the most important period of full development, feeding and management are directly affected by the level of performance of duck production. In the incubation period, to take full advantage of the physiological characteristics of young ducks, the breeding of scientific management to ensure the full development of bones and muscles, improve life skills; appropriate restriction mature reproductive organs, so in the appropriate weeks to reach maturity and body ######ual maturation and growth and development of its neat, open the same production period for laying a good foundation for high yield and improve the performance of open post-production.
5. Adaptive plasticity. As the age increases, improved ability to regulate body temperature, increased ability to adapt to the outside world, and because of the growth of feathers, warm gradually increase capacity.
is actually a drinking water disinfection of drinking water disinfection, water sterilization practice is to kill microorganisms in drinking water or control of animal pathogens in vivo. If any of the drugs increased the concentration of disinfectant in water or long-term drinking, it may cause acute poisoning, it can also kill or inhibit the normal intestinal flora, on the Animal Health hazard. Therefore, disinfection of drinking water should be preventive, not therapeutic. Chlorine disinfectants: that dissolve in water to kill microbial activity produces hypochlorous acid with disinfectant, and its active ingredients to kill micro-organisms that usually chlorine. Such disinfectants include: inorganic chlorine compounds such as sodium hypochlorite (10% to 20%), bleach (25%), calcium hypochlorite (calcium hypochlorite-based 80% to 85%), chlorinated trisodium phosphate ( 3-5%); organic chlorine compounds such as sodium dichloroisocyanurate (60-64%), TCCA (87% to 90%), etc.; inorganic chlorine unstable, vulnerable to light, heat and moisture effects, the loss of its active ingredients, organic chlorine is relatively stable, but soluble in water are unstable after. They used to kill microorganisms significantly affected the concentration of the impact of the role of time, generally speaking, the higher the concentration of available chlorine, the role of disinfecting effect of the longer the better. The lower the PH value of the sterilization effect is better; the higher the temperature the stronger the effect of microbicides; but when the organic matter (such as blood,
jordan heels for women Man you really love, saliva and droppings) the presence of disinfection effect can be significantly decreased. You should increase the concentration of disinfectant or extended duration.
(1) limit law. Limited supply of feed, in the case of high levels of dietary nutrients, the appropriate reduction in its intake. Limited according to the season before feeding, hatching date, body weight standards, feed and feeding restrictions and other conditions to develop feeding programs. Specific methods are: restricted feeding every other day to 2 days of feeding concentrated in 1 day Wei Wan, do not feed the other day; weekly limits the amount of the 7-day feeding Wei Wan shared equally in 5 days, 2 days without feeding; 4 / 3 restricted feeding, the amount of the 7-day feeding Wei Wan shared equally in 4 days, 2 days not fed; 6 / 1, restricted feeding, the amount shared equally fed 7 days in 6 days Wei Wan, 1 day do not fed; 3 / 2, restricted feeding, feeding the 5-day volume Wei Wan in 3 days, 2 days without feeding; 2 / 1, restricted feeding, the amount of the 3-day feeding Wei Wan shared equally in 2 days, 1 day without feeding, etc. and so on. 2 / 1 restricted feeding methods, feeding ducks bred more need, the best results.
Daily morning at a fixed time (usually 7 am) to duck from the training, the duck will be a habit, during the day in
(3) cooling water in the hot season, do not spray to the egg box area, and can not be wet ground and litter.
disinfection management
⑴ species of duck egg production and egg quality, egg fertilization rate, hatching eggs, ducklings healthy young drake mating rate and the kinds of forces, such as semen quality.
bred ducks feeding and management
1. Adjust the density in general, growing period fed on the ground not more than 5 per square meter, depending on the specific premises to be designed keeping the density, weather conditions, feed and water equipment and ventilation and other decisions. Sports and outdoor reared in breeding ducks bred should ensure that no more than one per square meter, and the ground should be well drained site, with shading, the best surface for the cement or sand.
(1) General Management feeding method. Must supply of clean, fresh feed and water. The full price of feed for breeding ducks with ducklings feed material to be better than the coarse particles, to the late great duck feed material particles and as thick; also be fed with powder, but the ducks feed on the small amount of powder, difficulty swallowing, waste more more. Converter material generally requires 3 to 5 days of transition time, or the feeding of ducks, digestion and absorption of large, stress big.
2. Feeding
1 makes mechanical removal before disinfection
restricted feeding, weight control, only the combination with the lighting control in order to effectively control the breeding of ######ual maturity and open duck production time. Three should complement each other, arranged, carefully executed. Duck incubation period is most vulnerable to problems in life stage light, light is too long or too short will cause some economic losses. If the incubation period of light for too long, will lead to early ######ual maturation and premature opening production, egg less, a small egg weight, fertilization rate, etc.; if the exposure time is too short, can lead to delayed ######ual maturity, open production delays. Open duck house should be based on hatching date, the local sunshine laws, to make reasonable lighting system. About 8 weeks from the pre-opening, can provide appropriate artificial lighting, an increase of 0.5 to 1 hour per week. Laying the longest time to reach the peak of light; increasing illumination time to start from the beginning, day light time can be kept constant or increased gradually, but certainly not reduced because of the normal lighting system is interrupted or the illumination time is reduced, will cause production eggs was reduced and difficult to restore. Best day light for 18 hours. Artificial light is best added in the morning before sunrise, as this will promote all of the duck egg in the morning before sunrise.
1. Breeding ducks feeding technique
(2) limit the quality method. Restriction of feed quality, and does not restrict intake, the nutritional level of the control diet, reducing dietary crude protein and energy content, increased cellulose content. However, calcium, phosphorus and other minerals and trace elements and vitamins are still guaranteed to meet the needs, to promote bone and muscle Duck normal growth and development.
③ accurately calculated after weighing each lap, each of them, the whole group, the average body weight and weight uniformity; calculated weight uniformity, to a standard body weight and the actual average weight ± 5% were calculated, accordingly ducks uniformity of weight and make the correct assessment.
(3) to ensure adequate intake, and make each duck feed to obtain the quantitative equality of opportunity. The distribution of feed and water equipment shall be uniform.
4. Manage egg boxes and bedding
4. Bred to speed up until the late development of ######ual organs mature
3. Before the ducklings arrive, so the brood chamber for 12 hours in advance to 30 ~ 32 ℃;
fed on the ground. In the shop there is dry and clean litter on the ground level support. Incubation feeding ducks outside the combination should be discounted homes, it will take captive venue with an outdoor playground, especially in the back half of the breeding ducks should be allowed to appropriate activities and sports venues in order to enhance physical fitness. All homes should be smooth inside and outside the ground, and kept clean and dry, shed the ground floor should be concrete, stone and other hard floor surfaces, and easy do not water; the best outdoor venue for the sand,
nike air max hyperize, good drainage properties, and with shading devices, such as trees, artificial arbor and so on. Water for the ducks are ready to swim, swimming, water sanitation requirements, there can be pollution and dirty smelly phenomenon. All the ground should be less than 25 degrees slope, land and pool in the ground should be gradually tilted junction transition, should not be above the water surface slope and sudden phenomenon.
4. Appropriate humidity
(1) net bed brood. Bed and use the network appliances and floor clean,
(3) fumigation. , 21 grams per cubic meter of space with potassium permanganate
restrictions intended to prevent young people keeping ducks caused by eating too much material too early or too fat ######ual maturity, thus ensuring the normal growth and development of duck duck and satisfy the reasonable needs for nutrients.
① said the important early, brood care is necessary to reach the ducklings weigh birth weight and later weighed at least once a week.
disinfection of drinking water
2. Bone, muscle growth and fast, but the growth rate of weight increase with the diet tended to decrease. Feathers grow by molting feathers. Of the increased demand for calcium and protein
duck control of body weight and level of uniformity and duck egg production peak, peak to maintain the length of time, the whole egg laying period is closely related to the total. Throughout the incubation period of all the work should focus on the work.
But the high concentration of chlorine disinfectant
Finally, covered with litter, put a good brood appliances and fumigated.
duck egg-laying period usually ranging from 4 to 5 years, 1 duck opened the first postpartum year (equivalent to 18 months), the highest egg production, more than 2 years decreased ability of duck egg production (more than 1 year 20 ~ 30% reduction), 3 years of duck egg production is less (lower than the first 2 years more than 35%). That is, the older the duck, the lower egg production and egg fertilization rate and hatching rate is lower. Therefore, in order to use a duck egg in the most economical, that is, to get into a duck from hatching to 18 months out of 17 most cost-effective, market and other reasons for Forced molting through the use of the second laying year. Breeding ducks useful life, need to be extended according to breeding, without the above conditions.
play the role of disinfectants, drugs must come into contact with pathogenic microorganisms, but was sterilized on the spot there are a lot of organic matter such as manure, feed residues, animal secretions, skin shedding,
asics running socks, and rat feces, sewage or other contaminants, these organisms have a large number of pathogenic microorganisms in hiding. At the same time, disinfectants and organic matter, especially with different degrees of affinity proteins can be combined as insoluble compounds, and hinder the role of disinfectants to play. Moreover, disinfectant consumed by the amount of organic matter, severely reducing the role of the concentration of pathogenic organisms, so that the complete mechanical removal is a prerequisite for effective disinfection. Royal mechanical removal should be preceded by the removal of appliances such as food grains, sinks, cages, boxes and other care earners removed, transported to homes outside the cleaning, soaking, washing, shaving brush, and repeated disinfection. After the removal of appliances, equipment, discounted from the roof, walls, doors and windows, until the ground and septic tanks, drain cleaning, etc. in order to seriously clean, then rinse with high pressure water until completely clean. Prior to cleaning the clear, it is best sprayed with disinfectant spray and drugs to prevent pathogenic microorganisms flying rolls around the water discharge, spread to the adjacent animal building and the environment, causing widespread pollution.
2. Living area to be trained by the habit of feeding duck and water activity area and activity area separated egg (The design of the exclude water, there is a small dry bedding area.
the daily management of breeding ducks
(5) of the weight handling of very small duck. Mei Dong set up a special motorized duck pens, as a small duck in a small circle within a visual body weight per day will be large group of relatively small duck duck ring singled to separate feeding of small and relatively easy to identify with the color of the body in the duck cook mark, easy to feed in each feed after the pick; after each feeding a separate meeting should be finished in time back into the large group of ducks; this work is repeated until the date of their body weight up to standard.
1. Improve the level of nutrition diet
brood management
(2) feeding method requirements. Feed must be evenly distributed to homes outside the movement area is large enough, with the increase in time spread the growth of duck feeding area, and pay attention to prevent the following:
bred ducks feeding and management
② weight ratio of not less than 10%, said the important point, timing, people.
1. Drinking water
⑵ depends on the level of reproductive performance and breeding management of genetic properties of two basic factors, duck feeding and management is the most important factor. Feeding and management science can duck their full genetic potential for optimal reproductive performance. Duck's brood should duck brood than meat products more carefully these, the best duck's brood in the spring.
(2) observe the feed changes, such as every other day feeding method, feeding the feed should be finished in 4 to 6 hours; if that changes in feeding time, you need to check the reason for feeding it too much or the amount of too small, with or without stress and disease and so on.
rearing duck weight control is the most important, we need to do a good job of feeding and management science, and to duck to create a good environmental conditions to minimize stress, cultivate healthy disease-free,
mbt sport 2 shoes, with excellent breeding body condition, orderly development of consistent, high-yield species of standard weight and give full play to duck ducks the best reproductive performance.
(5) adjust the feeding amount of accurate weighing, the average weight of ducks, feeding the amount of increase or decrease the rate should be 0.5 kg per 100 ducks the proportion of control, do not exceed the ratio.
(2) temperature control. As the ducklings grew up on the ambient temperature have a certain ability to adapt, to be cool. Brooding temperature should be high to low, gradually reduce the temperature when the temperature can not fluctuated, the temperature difference is too large, or colds.
must require a sufficient number of egg boxes, the design of good quality, easy to duck out of the egg outside interference can be avoided. Every four should be equipped with a duck egg boxes, egg boxes litter must be soft, clean, dry, good litter than other places, so that ducks are the most comfortable inside the egg, and like products laying eggs in the box. If you see droppings and broken egg laying in the box with dirt, etc., should be immediately removed, replace the dirty wet bedding. The litter box is best egg shavings, followed by the chaff, wood chips and replace the litter at least 2 times per week, spread out the old litter the ground in the duck the other, then the most fresh, soft bedding shop into the egg box. If the ducks in the outdoor activities rainy day more easily understood when the wet ground and bedding, egg boxes need replacing all the litter every day. Bedding must be mildew. Litter on the ground also must be kept dry, clean, soft, wet if its dirty, not only can affect the duck's egg, and egg cases of health, thus affecting the cleanliness and hatching eggs results. Dirty wet litter can also cause leg and parasitic diseases, which affect the public, duck mating and fertilization rate, lead to other epidemics.
Fuller added 42 ml formalin, 24-hour closure of fumigation, ventilation windows 1 to 2 days.
(3) limit law. Limited feeding, or reduce the feeding times, or shorten the feeding time, the nature of law is limited.
(1) In order to ensure reasonable growth and higher body weight uniformity, we should note the following:
(2) Ventilation. Natural ventilation and forced ventilation. Natural ventilation: for by the temperature difference between indoor and outdoor ventilation, such as opening windows and doors, vents and so on. Small temperature difference or the effect of low air pressure differential, but low cost. For small span, building a shorter brood chamber. Forced ventilation: Use ventilation equipment for ventilation. Good ventilation, but the investment is large. Applicable to span a larger premises longer brood chamber.
1. Rapid growth, development of strong, healthy functioning of various organs. Digestive organs increased digestion of feed increased.
(2) drinking must be placed in well-drained places, such as the area does not drain or playgrounds, should be immediately removed the overflow of dirty water and not get wet ground and litter.
sick ducks in the second duck duck or no productivity, should be eliminated as soon as possible, normal duck out and deaths each month should not exceed 1% of ducks, more than this standard, you should thoroughly check feeding and management methods and procedures for immunization administration. Drake's out, you should refer to a reasonable public duck ratio.
(2) ensure adequate and clean drinking water. Equipment cleaning and disinfection of drinking water every day to ensure clean drinking water, adequate water constantly; into the child a week is best to drink warm water
order to prevent feather pecking and duck eggs, in addition to keeping the floor and litter drying, the need to pay attention to breeding density, as soon as possible to collect eggs (especially egg playground), and pay attention to nutritional balance. Duck can not be more than 250 per duck group, each duck supply of at least 0.5 square meters of
(3) weighing and Notes:
4. The control of body weight and uniformity
disinfection procedures should be, not haphazard whim. General can be discounted in the following order from top to bottom (from the roof, walls, doors and windows to the ground, the same below) → disinfectant spray out a large number of utensils and equipment and removal of cleaning from top to bottom → → → remove manure and other dirt high-pressure water washing → drying → full from top to bottom and the air with a disinfectant liquid spray, fog particles should be fine, some of the fog particles can stay in the air for about 15 minutes → drying → for another type of drug spray disinfectant equipment commissioning → → closed doors after fumigation with formaldehyde, if necessary, coated with 20% lime slurry wall, about 2 m → will have good equipment and utensils disinfection hires move doors and windows closed after the installation and commissioning → fumigation with formaldehyde, if necessary, after three days peracetic acid and then once a → enclosed space fumigated homes 7-15 days before that the sterilization process is complete. Such as the urgent need, in the 24 hours after fumigation, open doors and windows ventilation 24 hours after use. Some of the requirements of all in all out do not understand, often in clear round disinfection, will be transferred to the remaining group or the number of slaughter when the first (only) the growth of backward or sick animal can not be transferred out of the original joint left in the can that retained one of the original hires (only) of livestock and poultry, can not be considered in all out to do the whole.
optimum temperature brooding temperature control recommendations are as follows
3. Fat deposition began to increase, it can lead to obesity.
(2) feeding method and frequency. Ensure that each feed ducklings can eat, eat but not eat too far;
(5) out of sick time duck
8 ~ 14 days 28 ~ 22 ℃;
15 ~ 21 days old feed once every 4 hours;
2. Restricted feeding
lime is a disinfectant power is good, no bad smell, cheap, pollution-free disinfectant, but often used incorrectly. New lime kiln is calcium oxide, quicklime is equivalent to the weight of 70% by adding a 100% water, which generate loose hydrated lime, ie calcium hydroxide, only that the dissociation of the hydroxide ion has a bactericidal effect. Some courts, indoor pool in the admission or entry of livestock and poultry, a thick pile of dry lime, to shoes,
supra ns Longer follow even just listening to .., step through, it would not achieve disinfection. And some place for too long with slaked lime to do disinfectants, but it has absorbed carbon dioxide in the air, has become no hydroxyl ions of calcium carbonate, has completely lost the sterilization effect, so it can not be used.
proposal density as follows:
3. Temperature
feeding duck drake is not just duck there, not only to keep a good species of ducks, but also to keep a good species drake, can improve the fertilization rate, give full play to duck the reproductive performance.
