The Uda ram (Ovis aries) is the predominant species in the Northwest of Nigeria, and the morphology of the testes is an important marker for the reproductive capability of rams. Rams play a pivotal role as a source of livelihood and food, providing milk and meat. This study was conducted to determine the morphometry of the testis for this species during the dry season. This study was conducted by acquiring and assessing the testicular samples of eighty (80) rams during the dry season months to contribute data on the reproductive function during this period. Testicular weight was observed to vary significantly, with the right testis showing greater mean values than the left. The weight of the right testicles varied from 82.00 to 218.00 g (191.80 ± 40.90 g), whereas the weight of the left testicles varied from 74.00 to 210.00 g (184.50 ± 41.70 g). The range of whole testicular weights was 156.00 to 428.00 g (376.30 ± 81.70 g). There were statistically significant (p < 0.05) variations in length, breadth, and circumference, indicating a right-sided predominance. Age and body weight were observed to have a significant association with testicular dimensions. This study also provides baseline morphometric data for Uda rams; the results support reports on lateral asymmetry in testicular morphometry that favours the right side, and they highlight key predictors of reproductive potential.
