| Sumario: | Fifteen Red Sokoto goats (bucks) aged 2 to 2½ years with a mean body weight of 17.80±1.24 kg were used fer studying daily spermatozoa output, testicular and epididymal sperm reserves. Semen ejaculates were obtained from each buck and evaluated daily for six weeks. Semen characteristics were as follows: volume, 0.72±0.91ml; colour, milky/creamy; sperm concentratien/ml, 0.61±0.05 x 109; mass motiiity, 3.80±0.33; individual motility, 77.50±5.60; and normal sperm + morphology, 80.00±10.50. Mean scrotal circumference was 21.80±0.29. Mean testicular and epididymal (capita, corpora and caudae) weights (gm) were 83.74±5.33, 7.27±0.63, 2.22±0.23 and 6.13±0.73 respectively. Corresponding sperm reserves were 44.32±5.79, 8.82±1.95, 4.99±0.86 and 5.64±7.87 billion. Scrotal circumference was positively correlated to testicular weight (r= 0.86), testicular spermatids (r = 0.77), and caudae spermatgzoa (r = 0.83).
