Illuminating farming method to adjust and control sexual maturity of high-quality broiler breeders

Abstract

The invention discloses an illuminating farming method to adjust and control sexual maturity of high-quality broiler breeders. Illuminating is carried in first 3 days for 23L-1D under illumination intensity of 100 Lx; from the 4th day, illumination time is 2 h less each day, the illumination intensity is 10 Lx less each day; at the end of 4 weeks, the illumination time and the illumination intensity are 8 L-16 D and 8 Lx respectively; from the 5th week, the illumination time and the illumination intensity for each day are respectively 8 L-16 D and 8 Lx until the end of 14 weeks; from the 15thweek, the illumination time is 2 h more each week while the illumination intensity remains unchanged; the illumination time at the start of laying is 16 L-8 D, the illumination intensity is 30 Lx, theillumination time remains unchanged by this time, and the illumination intensity is 10 Lx more each week until the end of 66 weeks. After the illuminating farming method is used, the laying start ageof 5% of chickens is 10-12 earlier, their weight at the laying start is 50-60 g higher, and the laying start age of all the chickens is 10-14 days earlier, with their weigh at the laying start increased by 40-50 g.

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.
