First, a reasonable selection of good chickens, without reasonable matching, let them mess with random, then, the resulting offspring will not be good. Therefore, in the same breed of chickens, a particularly excellent cock is selected for every 8-10 hens and has unique properties such as fertilization rate, hatching rate, strong disease resistance, or a distinctive appearance. The advantage of using this rooster is to select hens with similarly good traits for mating. This matching result will significantly increase the production performance of offspring. 2. There are many excellent varieties for the purification and selection of excellent chickens. In one area, chickens of the breed that are adapted to the local natural conditions, production performance, and economic value are welcomed. Practice has proved that it is better to promote a variety in a region, so that the speed of development is rapid, the effect is significant, and it is not easy to mix. At the same time, if the chickens with disordered coats, premature moulting, too late egg production, and particularly small eggs are found, they should be transferred or eliminated immediately. 3. Establishment of hatchery and brooding points In areas where broiler chickens are promoted, hatchery brooding points need to be set up in all key farms, and the introduced fine breed eggs should be hatched at the point and raised for about 10 days before being sold to the farmers for feeding. At the same time, they should also be taught to breed chickens with scientific management and disease prevention techniques. IV. Strictly Selecting Breeding Breeders When the number of fine-bred chickens introduced reaches a certain number, local poor-bred chickens should be phased out gradually, from less to more, from roosters to hens, and finally replaced by improved breeders. In the process of achieving improved seedlings, attention should also be paid to the selection of breeding chickens. In particular, the selection and breeding of breeding roosters should be strengthened, and identification of improved varieties should be carried out. Gradually breeder chick breeding systems should be gradually established so that excellent and productive chickens can be sustained for a long time. keep it up.
