Abstract

The testicular and epididymal sperm reserves of 32 adult crossbred European boars (mean age 17.4 months, range 15--21 months) raised and maintained in Ibadan, Nigeria were 43.77 x 10(9) and 207.20 x 10(9) cells respectively, and were correlated (P less than 0.01) with age and organ weight. The distribution of spermatozoa in the epididymis was 16, 6 and 78% in the caput, corpus and cauda epididymidis respectively. The testicular and epididymal sperm reserves were correlated (P less than 0.05), suggesting that sperm production and storage are associated. All the values studied were comparable with those reported for boars kept in temperate climates.

摘要

在尼日利亚伊巴丹饲养的32头成年欧洲杂交公猪（平均年龄17.4个月，范围15 - 21个月），其睾丸和附睾的精子储备分别为43.77×10⁹个细胞和207.20×10⁹个细胞，且与年龄和器官重量相关（P < 0.01）。附睾中精子的分布在附睾头、体和尾部分别为16%、6%和78%。睾丸和附睾的精子储备相关（P < 0.05），表明精子产生和储存是相关联的。所有研究值与温带气候下饲养的公猪所报道的值相当。
