| Abstract | ||
| The study was conducted to determine the effect of force molting program on fertility (%) and the semen characteristics including mass motility ,individual motility (%), ejaculate volume (ml.), sperms concentration and number of sperms per ejaculate. The study used Hubbard flex broiler breeder flock at 65 week of age consist of 24 cocks and 40 hens . The cocks divided into two groups ,the first group and all hens were subjected to force molting program while the second group of cocks were used as control. Semen collected artificially and examined to evaluate the semen traits and the hens artificially inseminated with 0.05 ml. semen with four replications. Eggs were collected through 2-8 days after insemination and incubated for seven days before they broken and examined for embryo development to determine fertility. The results indicated that there were significant (P< 0.05) reduction in fertility, mass motility and individual motility and highly significant (P< 0.01) reduction in sperms concentration for the force molted cock semen as compared with the control group. | ||
