1. Formulate the plan for brooding.
The number of brood should be consistent with the capacity of brood house and adult chicken house. Considering the factors such as weak brood, male brood and epidemic disease, the number of brood should be slightly more than the number of adult chickens contained in the henhouse. The formula can be used to calculate: the number of brood = the number of adult chickens *1.08. The number of chickens in addition to the chicken house capacity, feeding management, chicken quality and other factors should also be taken into account the market, the amount of funds and so on.
2. Formulate regulations for feeding management.
Before purchasing the chickens, the rules of feeding and management should be formulated, including disinfection, immunization, feeding quantity and times, light, temperature, humidity, ventilation and so on, and strictly implemented. In addition, various forms of records should be made and pre job training for brooding personnel should be done well.
3, the choice of brooding season
With the rapid development of chicken industry and the continuous improvement of chicken raising technology, large-scale mechanized commercial chicken farms with strong specialty have been built and put into production one after another in various parts of China. In particular, closed poultry houses are less affected by seasons. However, in some small and medium-sized commercial chicken farms and specialized household chicken farms, due to the limitations of equipment conditions, chicken houses are open or semi-open, and can not completely control the environment of chicken breeding, so we must choose the appropriate breeding season. Different breeding seasons, chickens in different environments, their growth and development and survival rate are also different, laying hens in the future production performance also has a certain impact. Generally speaking, brooding is the best in spring, followed by early summer and autumn and winter, and worst in midsummer.
4. The choice of chicks to breed.
The scale of breeding farm, the level of feeding management, the management of hatching farm and hatching technology are the most important factors affecting the quality of chickens. Chicken farms and hatchery should be thoroughly investigated before ordering chickens. The breeding chickens are required to be free from highly pathogenic avian influenza, Marek's disease, Newcastle disease, infectious bursal disease, infectious anemia, infectious encephalomyelitis, leukemia, white diarrhea, paratyphoid fever, mycoplasma and other vertical infectious diseases, and to have a higher level of maternal antibodies. The breeding chicken farms have the relevant departments issued the "Breeding Livestock and Poultry Production" Business license, "animal epidemic prevention certificate" and other related documents, and carry out production and operation activities according to law. At the same time, we should also understand the feedback and evaluation of the laying hens farmers, and listen to their opinions and construction.
5. Selection of chicken breeds
At present, the dominant breeds of laying hens in China are high-yield breeds imported from abroad, mainly Hailan series, Roman series and so on. Last year, China has newly bred Yukou laying hen "Jinghong 1" and "Jingfan 1" with independent intellectual property rights, good production performance, suitable for China's feeding environment, breaking the long-term pattern of laying hen breeds subject to people, completely dependent on foreign imports, but also a better choice.
6, chicks health condition choice
When purchasing chickens, the chickens should be selected and checked in the hatchery, and the steps of "one look, two touch, three listen" should be adopted. See as: tap out the chicken dish with the hand, observe the performance of chicken seedlings, reaction is sensitive, big eyes or make a loud call, is healthy chickens; and curl up the body, lying flat, listless is weak chickens. The second touch is: holding the chickens gently, touching the abdomen of the chickens with the index finger and middle finger, warm and soft, flexible, smooth umbilical cord mouth, abdomen does not stretch to the anus for the healthy chickens; while the abdomen is loose and inelastic or hard and dry, the umbilical fold uneven for the sick chickens. Three hearings are: crisp and loud, beautiful music for the healthy chickens; weak, sharp, weak for the sick chickens.
