ABSTRACT

Saleh WM., Effect of breeding and non-breeding seasons on testes, epididymis weights and size and sperm in rams, Onl J Vet Res., 27 (11): 604-611, 2023. Author reports effect of breeding and non-breeding season on 40 testes and epididymis weight and size from 6-24 month old donor rams. From 6-24 months age testes weights varied 87-210gm and measured 35.50-76.6mm respectively, epidimys were 12.7-18.4gm and 12.2-13.8mm, respectively. During breeding season same values were 201.8-210.3gm and 60.5-61.3mm whereas non-breeding 211.2-211.8gm and 60.1-62.8mm, respectively. For epididymis same values were 14.2-15.1gm and 14.6-15cm and caudal part 4.8-5.2cm and non-breeding 209.4-211.8 and 60.8-62.1mm whereas breeding 14.8-15.2gm and 14.7-14.8cm) and caudal section 4.8, 5.3, 5.1cm. During breeding season sperm were 80-85 viable, 85 motile, dead 18-20 and 78-80% alive, whereas during off season 40, 35-40, 60-65 and 35-40%, respectively. As expected, our results show that increased age was associated with enhanced testes and epididymis weight and size. We found no effect of breeding season on same parameters. However, author found highly significant (P < 0.0001) enhanced motility and viability in sperm of breeding rams compared with non-breeding ones. Similarly abnormal sperm were much less in Breeding rams.
