Abstract

The present study was carried out to investigate the reproductive activity of mature Iraqi bull buffaloes and effect of month’s changes on the testes activity. Two hundred and fifty testes of mature buffaloes bull were taken from the slaughter house from December 2010 to September 2011. After slaughtering the length and width of the right testes were measured weight of the testes were also taken then carefully the epididymis were dissected. The diameters of testicular seminiferous tubules were also measured. The present study demonstrated a significant increased (p<0.05) in weight (g), length and width (cm) in the testes in March and April. The diameter of the seminiferous tubules demonstrated higher (p<0.05) significant in April, March and May, thickness of seminiferous tubules demonstrated higher significance in April, May and March. The increase in spermatogenesis process lead to increase the diameter and thickness of seminiferous. Conclusions reproductive activity of bull buffalo and semen physical characteristics decreased in hot months and increased in the moderate and cold months. The increase of ambient temperature in hot months lead to disturbance in reproductive activity but didn’t stop it.
