1, young chicken refueling can not be eager to achieve. Refueling young chickens, can not be directly replaced with laying hens, nor suddenly refueling. If you are eager to complete the refueling in one time, the composition of calcium and crude protein will suddenly increase, especially the protein will increase, the amount of drinking water will increase, and the body of the chicken will cause diarrhea due to poor digestion and absorption. Therefore, the young chickens are refueled, the feed contains calcium at about 0.8%, and the crude protein at around 15.5%.
2. Refueling time selection . For refueling of laying hens, it is best to switch to laying hens when the egg production rate reaches 2%-5%. The yoghurt feed should contain 3.4%-3.5% calcium and 18% crude protein. When refueling, if it is a young chicken cultivated by natural light after the summer, it is often started late, and it can be refueled at 18 weeks of age; if it is a reserve chicken cultivated by natural light after winter, it is often opened earlier. Refueling at 17 weeks.
3. Refueling the laying hens should first be carried out according to the standards of breed breeding. Generally, 19-20 weeks old chickens are fed with pre-production materials, also called transition materials. The calcium and protein components in the feed should be increased compared with the feed of young chickens. The ratio of calcium is generally 1%, and the crude protein is 16.5%, when refueling, the refueling process is gradually completed in about half a month, and it is not possible to change the material suddenly and quickly.
