The two main objectives of the present study were a) To compare fertility results of artificial insemination performed with liquid boar semen diluted in PRIMXcell and NBSE extenders. b) To study the efficacy of PGF2α (175 µg D-Cloprostenol) for synchronization of estrus in seasonal infertile pigs. An experiment was designed with 32 crossbred LWY pigs which were randomly divided into two groups: group 1 (12 cycling animals) and group 2 (20 seasonal anestrus pigs) which were further divided into two subgroups (6 animals in each sub group) to study the efficiency of PRIMXcell and NBSE extenders. The animals which responded for D-cloprostenol i.m. injection were 60% (12 of 20). The mean interval for onset of estrus was 3.75 ± 0.44 days, mean duration of estrus was 42.00 ± 1.80 h. The overall conception rate (%) was higher with NBSE than PRIMXcell (75 Vs 66) which did not differ significantly. The results of the present study indicate that AI can be practiced with NBSE which is as good as PRIMXcell.
