A cannula and collection system are described which permitted collection of semen directly from the epididymis via the ductus deferens from conscious boars while also simultaneously collecting semen via the ejaculation process. The cannula consisted of silicone rubber tubing that was surgically inserted into the ductus deferens 10 to 12 cm from the end of the cauda epididymidis. Cannulas were successfully used in 4 boars. Average daily output of spermatozoa was 11.2 times 109 and 12.4 times 109 from cannulated side and intact side, respectively.
描述了一种插管和采集系统，该系统允许在公猪清醒状态下通过输精管直接从附睾采集精液，同时也能通过射精过程采集精液。插管由硅橡胶管组成，通过手术将其插入距附睾尾末端10至12厘米处的输精管。插管在4头公猪中成功使用。插管侧和未插管侧的精子日均产量分别为11.2×10⁹和12.4×10⁹。
