متن کاملEffect of Timing of Artificial Insemination on Fertility and Hatcha
The influence of timing of artificial insemination on fertility and hatchability of breeder hens was carried out by inseminating breeder hens at 10:00 hr and 15:00 hr with pooled semen from Shikabrown White breeder cocks for four weeks. Fertile eggs were collected two days after the first insemination and stored at a temperature of 16 C for seven days before incubation. Fertility was higher (P ...
