The principle of picking
1. Chickens should be derived from healthy and Infectious Bursal Disease (IBD) negative breeder flocks. If it is necessary for young chickens to use a group of birds that are positive for IBD, they must be separated. Only one chick from a positive breeder group or only one chick from a negative breeder group should be kept in one area and not be mixed in the same area.
2. Only chicks that use MG (Chicken Septic Enzyme Profile) and MS (Symponoid Enzyme) and Salmonella-negative breeders.
3, chicks should be hatched from 52 grams or more eggs. In broiler chickens, chicks hatched from smaller eggs need to be kept separately and not mixed with other chickens.
4. The chicks are uniform in size and color, clean, dry, loose and long in appearance, and lustrous.
5, eyes round and bright, smart, healthy and lively.
6. The abdomen is soft and the yolk absorbs well; the umbilicus heals well and there is no infection; the villi around the anus do not stick into a paste; the skin of the feet is bright like a wax and does not appear dry and fragile.
7. Chickens do not have any obvious defects, such as leg-turning, torticollis, eye defects or cross-diagnosis.
8. Adopt the "all-in, all-out" feeding system. That is, within the same range, only the same batch of chicks are raised and the same age is raised, and they all appear on the same day. Thoroughly sweeping, cleaning and disinfecting after exiting and cutting off the circulating infection of pathogens.
