dc.description.abstractThe present investigation was conducted to compare the reproductive performance of three breeds of pigs viz; Large White Yorkshire, Landrace and Hampshire during three seasons. The relationship between reproductive efficiency and blood biochemical profile during different stages of reproduction was also studied. Furthermore, the changes in vaginal epithelium during different stages of oestrous cycle and pregnancy were observed using biopsy technique. (1) The average age at puberty in Large White Yorkshire, Landrace and Hampshire was noted as 320.541.95, 314.68 ± 1.62 and 316.52 1.56 days. The influence of breed on attainment of puberty was significant (PL 0.05). The influence of season on puberty attainment was also significant (FL 0.01) and gilts born during rainy season attained puberty earlier as compared to gilts born during winter and summer season. (2) The mean duration of oestrous cycle and average duration of oestrus did not differ significantly between breeds during different seasons. A significantly (PL 0.01) higher occurrence of oestrus was recorded during winter (42.16± 0.47%) than summer (24.16± 0.51%) and rainy season (33.10 ± 0.49%).en_US
