| The AA+ parental generation white feather broiler breeder broilers were used as experimental animals. The experimental animals were divided into 1 control group and 8 experimental groups. This study analyzed the effect of Broiler Breeders changed light intensity and variable light weigh on day and peak age(22-36 weeks old). This study aims to provide fast growth and healthy environment for AA+ broiler breeder to obtain more economic benefits. 1?The effect of AA+ broiler breeder same variable light weight and different light intensity on different opening day age and the peak of egg laying day.Under the standard weight, the opening day of age and the peak of egg laying day of control group 1 was later than experimental group 2. And the opening day of age and the peak of egg laying day of experimental group 2 was later than experimental group 3.Each group had the same changing light weight. The light intensity in the range of 30-50 lux, the opening day of broiler breeder and the peak age of the laying eggs were shorten with the enhancing intensity. 2?The effect of same light intensity and different variable light weight on opening day of age and the peak of egg laying day for AA+ broiler breeder.Under the same light intensity, the opening day in age and the peak of egg laying day of control group 1 was later than experiment group 4. The opening day in age and the peak of egg laying day of control group 1 was later than experiment group 4. The opening day in age and the peak of egg laying day of control group 4 was later than experiment group 7.Under the same light intensity, the greater the weight are, the earlier opening day age and the peak of egg laying day formed(variable light weight exceeds standard weight in the range of 200g). 3?The effect of AA+ broiler breeder different variations of light weight and different light intensities on different opening day of age and the peak of egg laying day.Under the light intensity of 50 lux, and the weight greater than standard variable light weight(200g) were the best environmental conditions for opening day age and the peak of egg laying day. |
