Effective Methods to Strengthen the Management of Breeder Chicken

High-quality breeders are affected by many factors. Nutrition is the prerequisite for excellent breeders. The intake of breeders directly affects the nutritional reserves of breeders, and the growth and development of embryos and chicks are related to the quality of breeders. Therefore, strengthening the management of breeders and improving the quality of breeders to ensure the good growth of chicks are important guarantees for providing customers with high-quality products and improving economic benefits.

1. Strengthen the management of breeders and improve the quality of breeders

In order to obtain high-quality breeding chickens, management is essential. The breeding of breeding chickens, the nutritional collocation of chicken food, vitamins, trace elements, and minerals are all factors that affect the quality of breeding chickens. The health of the breeder directly affects the quality of the chicks, and everything done in daily life may affect the quality of the next generation of the flock.

1.1 nutrition is appropriate, and the nutrition of chicken food before and during the laying period is the most important. During this period, the nutrients in the breeder will be transmitted to the breeder eggs. If the nutrients are insufficient, the mortality rate of chick embryos will be increased. The nutritional collocation of chicken food is very important. It is necessary to ensure the normal intake of various nutrients, and the collocation of nutrients and feed should be balanced.

1.2 ensure the consistency of breeding eggs to obtain high-quality chicks is the premise of healthy breeding chickens, and the quality of breeding chickens largely affects the quality of chicks. The weight of the breeder determines the quality of the breeder eggs to a certain extent, and also determines the indicators of the hatching chicks and the quality of the chicks.

During hatching, temperature and humidity can also affect egg weight. If the egg weight gap is large, it is difficult to make targeted adjustments in the temperature and humidity control links. The chicks hatched from eggs with smaller egg weight have poor disease resistance, high mortality rate, and are prone to dehydration. To obtain uniform egg weight, it is necessary to provide chicken food rich in minerals and amino acids in time to make it reach the standard shin length 56 days ago. At the same time, chicks should be picked out 56 days ago so that their weight can catch up slowly in 2-3 weeks, fail to catch up in 56 days, and catch up in 63 days at the latest.

2. Do a good job in chick breeding and improve the quality of chicks

2.1 properly keeping the breeding eggs and improving the hatching rate of chicks The cleaning of breeding eggs is the key to reducing early mortality and ensuring the quality of chicks. The best storage time for eggs is generally 5-7 days, not more than one week. For some elderly eggs, the storage period should be shortened. Air conditioner and insulation layer is one of the options for storing eggs, which can effectively adjust the temperature and humidity at any time. Ventilation is also one of the conditions conducive to the preservation of eggs.

In order to improve the quality of chicks, the breeder eggs produced by the breeder flock before 45 weeks are stored for about 3 to 5 days, and the breeder eggs produced by the breeder flock after 45 weeks are stored for 2 to 4 days. Storage 1~3 days temperature is 21~23 ℃,4~7 days 14~19 ℃, if more than 7 days temperature is 12~14 ℃ is appropriate. The relative humidity should be kept at about 75%. Too low or too high humidity can lead to reduced chick quality. 2.2 strengthen vitamin minerals to ensure the quality of chicks. Vitamin participates in most of the metabolic processes, and is an essential element in the development of embryos. Insufficient vitamin content in breeder chicken food will also affect the development of chicks, so In order to save, it is very unwise to reduce vitamin content in chicken food. The addition of 50 mg/Kg vitamin E to the 52-week breeding flock is the best, which can greatly improve the hatchability of the flock.

2.3 attention should be paid to artificial insemination. Only when the fertilization rate of breeding chickens reaches more than 95% can they be excellent, so that the hatching rate of breeding chickens can be guaranteed. Select high-quality roosters and strictly screen them three times, usually in the third and 8. 18 weeks, with the crown bright red first. After 20 weeks of rooster, the ingredients of chicken food should be paid attention to, and the proportion of vitamins, trace elements and minerals should be well matched. Insemination staff should be skilled in the process of artificial insemination, strict operation, health cleaning work to do a good job. The best insemination time is from 4: 00 p.m. to 6: 00 p.m. every day, and the semen volume is about 0.02-0.03ml. The collected semen should be delivered within half an hour, because the vitality of the sperm will decrease with time. affect insemination rate.

3. Clean environment, do a good job of immunization

3.1 the control of environmental conditions Good environmental conditions are the premise to ensure the hatching rate, the chicken house should be regularly sprayed, spray disinfection. The spray disinfection in the chicken house should be carried out every day, and the disinfectant should be replaced once every two weeks. Some excreta and dead breeders should be cleaned in time to prevent the virus from continuing to spread. The temperature and humidity of the incubator should be maintained under a balanced condition. Drugs should be replaced regularly to avoid the emergence of drug resistance.

3.2 do a good job of vaccination vaccination is an effective guarantee to prevent the death of breeding chickens, and can protect breeding chickens and their offspring. The best time for immunization was 12 and 18 weeks old, and the two inactivated vaccine of septicemia-synovial mold was injected once respectively. This method can effectively prevent the vertical transmission of the disease through eggs. Attention should be paid to the use of vitamin C and E during immunization. Breeders should be vaccinated with IBD inactivated vaccine once at the age of 110-120 days, so that chicks can have higher maternal antibodies to protect chicks when they are most vulnerable to infection in the future. The sanitation and epidemic prevention system must be strict. All foreign objects cannot enter the factory area, and disinfection clothes must be changed when entering the incubation room.

Conclusion

Cultivating a batch of good breeders requires a strict management process, the breeding plan of breeders must be strict, the nutrition collocation must be strictly controlled by experts, and the management personnel need to make a reasonable feeding plan in the feeding process. The selection of feed will have an important impact on the development of breeders and their offspring, and the nutritional quality of chicken feed should be improved from both economic and biological perspectives.
