Abstract

The invention discloses a light breeding method for controlling the sexual maturity of high-quality broiler breeders. The light time of the first 3 days is 23L-1D, and the light intensity is 100Lx. From the 4th day, the light time is reduced by 2h every day, and the light intensity is reduced by 10Lx every day, until 4 weeks At the end of age, the light time and intensity were 8 L-16D and 8 Lx respectively; from the 5th week, the light time was 8 L-16D every day, and the light intensity was 8lx, and continued until the end of the 14th week; Add 2 hours per week, and the light intensity remains unchanged. When the production starts, the light time is 16L-8D, and the light intensity is 10Lx, and the light time is increased by 2h every week; from the 20th week, the daily light time is 18L-8D, and the light intensity is 30Lx. The light intensity continued to increase by 10Lx every week until the end of 66 weeks. After adopting this light culture method, the age of 5% of the chicken flocks was advanced by 10-12 days, and the weight of 5% of the flocks was increased by 50-60g, and the age of the whole flock was advanced by 10-14 days. Weight increased by 40g to 50g.

Description

technical field [0001] The invention relates to a light breeding method for regulating the sexual maturity of high-quality broiler breeders. Background technique [0002] High-quality broiler is an important source of supply and transportation of high-quality poultry products in my country, and its huge market demand directly promotes the rapid development of high-quality broiler breeding industry. However, in recent years, the delayed sexual maturity and premature delivery of broiler breeders have caused the phenomenon that chickens cannot start production in time and reach the peak smoothly, which seriously affects the production and reproductive performance of broiler breeders. At present, the lighting technology for regulating the sexual maturity of high-quality broiler breeders is messy, and it is not uncommon to copy the old-fashioned lighting mode. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defe...
