Frequent semen collection and sperm reserves of the male Angora goat (Capra hircus).

摘要: Semen was collected from six mature and sexually rested Angora bucks at one-hour intervals five times a day on each of 5 consecutive days in the breeding season. There marked decline semen volume (P less than 0.001), sperm concentration 0.05) number spermatozoa 0.001) days. Successive ejaculates within differed only 0.001). The following year beginning season, weights testes epididymides reserves these parts were examined after slaughter bucks. mean paired testes, capita, corpora caudae (22.8 +/- 1.24) x 10(9), (9.4 1.19) (3.4 0.22) 10(9) (35.0 2.21) respectively. Epididymal correlated with testicular weight (r = 0.50, P 0.01) 0.42, 0.07), but not epididymal weight. daily production per animal season estimated to be 4.0-6.4 10(9).
