Four key points of selection and retention Management of improved breeding Chicken
I. selection of suitable quantity
With a good flock of chickens, without reasonable selection and misbreeding, the offspring will not be good. Therefore, in the flock of the same breed, one particularly excellent rooster is selected for every 8 Murray hens, and has unique excellent performance, such as fertilization rate and hatching rate will significantly improve the performance of offspring.
Second, purification and selection
There are many excellent breeds of chicken. In one area, we choose the breed that adapts to the local natural conditions, has high production performance and economic value, and is popular with the masses. Practice has proved that it is better to popularize a variety in a region, so that the development speed is fast, the effect is remarkable, and it is not easy to mix. At the same time, chickens with messy coat color, early molting, too late laying eggs and very small eggs should be transferred or eliminated immediately.
Third, establish a good incubation and breeding site
In the areas where breed chickens are popularized, hatching sites should be set up in all key farms, where the imported improved breed eggs should be hatched and concentrated for about 10 days before being sold to farmers for feeding. At the same time, they should also be taught the scientific management of chicken breeds and the techniques of epidemic prevention and control.
4. Strict selection of breeding chickens
When the introduction of improved breed chickens reaches a certain number, the local bad breed chickens should be gradually eliminated, from fewer to more, from Roosters to hens, and finally all be replaced by improved breeds. In the process of achieving improved breeding, we should also pay attention to the selection of breeding chickens, especially strengthen the selection and cultivation of breeding cocks, carry out the identification of improved breeds, and gradually establish a breeding system of improved breeds, so that the excellent and high-yielding chickens can be maintained for a long time.
