兔场人工受精方案

兔场人工受精方案 王台19场光照刺激同期发情试验方案 一、试验目的 利用光照刺激提高母兔同期发情。 二、试验地点和试验种兔 王台19场4号舍D系祖代种兔，包括经产种兔和后备种兔; 三、试验条件和方法 本试验是在以下条件基础上开展的: 王台19场4号舍:该舍经产种兔在4月30日(产后第5天)已经全部遮黑(前期是自然光照)，晴天中午光照强度在10lux以下。在产后14天用灯光控制光照强度。 试验方案: 1、 光照强度:自5月7日(产后14天)开始，全部用灯光控 制光照强度，每个笼位的强度达到60lux。 2、 光照时间:自5月7日早上(产后14天)开始增加光照， 光照时间为16小时，从早上7点到晚上23点为光照刺激 时间。 3、 在5月11日观察母兔发情状态，并记录发情率，同时注射 25IU孕马血清，后备种兔除外。 4、 带仔母兔在5月12日上午9点哺乳结束后用产子箱把仔兔 和母兔隔离，在5月13日下午2点打开产箱门，进行哺乳， 哺乳结束后开始人工授精。 ships of 72 and a half the Harbour, like room Tao Yuan.
