Feeding of high quality yellow feather broilers

Compared with fast-growing broiler chickens, high-quality yellow feather broilers have slow growth and long feeding periods. Therefore, their feeding and management have some characteristics: Feeding methods: High-quality yellow feather broilers have a slow growth rate, low body weight, and breast cysts basically do not occur. Cage culture can be used, especially in the finishing stage of the later period. Cage culture can significantly improve the fattening effect. In some large-scale high-quality yellow broiler chicken farms in Guangdong, fire-fed brooding takes place during 0-6 weeks of brooding, bamboo-fly or metal-mesh feeding is used for 7-11 weeks, and the animals are basketed and fattened 12-15 weeks later. 2. Appropriate control of nutrient levels: Feeding high-quality yellow feather broilers with dietary levels of broiler chicks will result in waste, and dietary nutrient levels should be appropriately reduced. It can be used on the basis of the nutritional requirements of Aiyiyi broilers, and the protein level can be reduced by 5-8%. For example, AA pre-chicken protein needs to be 22-23%, then the quality of the yellow-feather broiler's protein needs to be 20-21%; The energy level is reduced by 2-3%; the levels of amino acids, vitamins and trace elements can be reduced synchronously with the protein level. How much nutrient level is appropriate depends on the growth rate of high quality yellow feather broilers. The division of the rearing period should be extended. Broilers are 0-4 weeks old and 5 weeks old. The high quality yellow feather broilers can be divided into 0-5 weeks in the early stage, 6-11 weeks in the middle, and late stages. More than 12 weeks old. 3. Increased immunization content: Due to the longer feeding period of high quality yellow feather broilers, some immune content should be added compared to broiler chickens. For example, Marek's vaccine must be inoculated promptly after hatching, otherwise it is at the peak of Malick's onset. For fowlpox vaccine, broiler chickens are not immune in most cases, and high quality yellow feather broilers should generally be vaccinated (unless the northern part of the growing season is not in winter). The rest of the immunization projects should also be considered based on the characteristics of the region's disease.
