The present study was conducted toevaluate the testis biometry and number of spermatids at stage one of seminiferous epithelial cycle per sertoli cell in bucks in breeding and non breeding season. Twelve bucks were taken for experiment and divided into two groups (breeding season and non-breeding season) of six animals each. Testes were collected from slaughter houses nearby Navsari. The scrotal circumference measured was 21.72 ± 1.42 cm in breeding season and 18.83 ± 1.38 cm in non-breeding season. Age and weight of bucks, scrotal circumference, volume, length and width of testes were collected in situ. The weight of the testes measured for breeding season was 68.12 ± 1.02 gm while in non-breeding season was 57.87 ± 1.99 gm. The volume of the testes measured for breeding season was 65.80 ± 1.69 ml while in non-breeding season 65.43 ± 1.35 ml. The mean value of number of spermatids at stage one of seminiferous epithelial cycles per Sertoli cell in breeding season and non-breeding season were 12.07 ± 0.14, 11.65 ± 0.10, respectively. Highly significant (P < 0.01) difference was observed between seasons for number of spermatids at stage one of seminiferous epithelial cycle per Sertoli cell.
