Abstract
This study was conducted to investigate the effect of infusion of sterile boar and their semen as pregnancy antigen factor for improvement of production in gilts. We observed 160 gilts between 7 to 8 months of age that were divided into 4 treatment groups vie. A group-epidimetomized boar, B group-no sperm semen infusion, C group-vasectomized boar, and D group-control in a completely randomized design. The number of total pigs born(NT) of A, B, C, and D groups were 10.05, 10.44, 11.63, and 9.97 pigs, respectively(P<0.05). And the NT of C g.cup was the highest among treatment. The number of live pigs born(NB) was similar to NT The NB of C group (10.70) was higher than that of A(9.12) and control(9.11)(P<0.05). However, there was not significant between B and C groups. The progesterone concentration of C group was the highest compare to other group at the 6th day after breeding. However, the progesterone concentration of C was lower than other groups after 8th day. There were not significant among cortisol of A, B, C and D groups. According of the results of this study, the infusion with vasectomized boar and semen at estrus before gestation can be improved reproductive efficiency because of more litter size in gilts.
