Abstract
Swamp buffalo exhibited seasonal variations in daily sperm production and in daily sperm production per gram of testis parenchyma. Maximum rates occurred in the late wet season and early dry season. There was no spermatogenesis detected in 1-yr-old bulls. Daily sperm production per gram of testis parenchyma increased thereafter up to 3.5 yr of age, and was similar in all older age groups. Scrotal circumference in bulls of this age ranged from 20 to 21 cm. Scrotal circumference and daily sperm production increased rapidly up to maturity, and increased less rapidly thereafter. Mean±SEM daily sperm production per gram in 146 mature buffalo bulls was 14.04 × 10 6±0.39 × 10 6 and mean±SEM daily sperm production was 1.86 × 10 9± 0.07 × 10 9. Mean±SEM epididymal sperm reserves in adult bulls numbered 9.7 × 10 9 ± 0.07 × 10 9. These were distributed between the caput, corpus and cauda epididymis in the proportions of 28.82, 14.63 and 60.55, respectively. Mean±SEM epididymal transit time was 5.65±0.24 d.
