Abstract

Background: The quality of the frozen thawed semen is one of the most powerful factor affecting the conception rate in a buffaloes. The season may have its effect on post thaw seminal attributes and fertility. Therefore, current study was aimed to investigate the effect of winter and summer seasons on post thaw seminal attributes and conception rate from semen of Jaffarabadi buffalo bulls.
Methods: The study was conducted on four Jaffarabadi breeding bulls, 5-6 years old, to know the post-thaw semen characteristics based on total of 192 semen ejaculates evaluated and cryopreserved over one year period. 
Result: The mean percentages of post-thaw motility, live sperm, abnormal sperm, HOST reactive sperm, acrosomal integrity and first AI conception rate for semen cryopreserved during winter were 58.85±0.56, 67.06±0.77, 8.62±0.43, 58.52±0.67, 75.22±0.27 and 45.75±0.21, respectively, whereas, corresponding values for semen cryopreserved during summer were 56.35±0.43, 65.62±0.76, 9.08±0.51, 55.43±0.60, 74.29±0.22 and 43.50±0.11. The semen quality of post thawed samples were observed better during winter compared to summer season for artificial insemination with satisfactory first AI conception rate.
