Abstract

This study was conducted to determine effects of season on some reproductive parameters of WAD bucks. Nine apparently healthy WAD bucks, aged between 18 and 24 months and weighing 8-15 Kg, were used to evaluate the effect of seasonal variations on Live-Weight (LW), Rectal Temperature (RT) and Scrotal Circumference (SC) between January and December, 2013. Semen was collected monthly by electro-ejaculation method and evaluated for spermiogram using standard techniques. Results were compared between and within groups using analysis of variance for repeated measures. Values are significant at p ˂ 0.05. Seasonal variation significantly (p ˂ 0.05) affected RT and SC except total sperm morphological abnormalities. Means for the total sperm morphological abnormalities were 7.42 ± 3.21% (late dry), 3.42 ± 0.36% (early rainy), 6.33 ± 0.33% (late rainy) and 7.25 ± 1.18% (early dry). The total morphologically abnormal spermatozoa reported for the seasonal study was 6.10%. It was thus concluded that seasons does not have significant effect on the spermiogram of WAD buck, , however, they appeared to be most fertile during the early and late rainy seasons and least potentially fertile during early and late dry seasons.

Key words: spermiogram, season, buck, rectal temperature, reproduction
