Abstract

本发明公开了一种增加驴受胎率的鲜精人工授精方法,它包括鲜精采集、消毒稀释处理过程和诱导排卵定时输精过程,首先将采集的精液灭菌稀释,然后采用注射激素法使驴集中时间进行排卵,降低卵泡发育中闭锁的几率,并在排卵前10小时至排卵后6小时内、将消毒稀释处理的鲜精实施人工输精,输精剂量15mL,确保驴精子与驴卵子在具有受精能力的时间内相遇完成受精过程,使驴受胎。采用本发明采用诱导排卵定时输精的技术措施情期受胎率可达73.3%。

Description

增加驴受胎率的鲜精人工授精方法
技术领域
本发明涉及牲畜人工授精方法。
技术背景
驴属于马属动物,为了增加繁育量,一般采取人工授精方法。由于马属动物的卵巢结构的特殊性,在出现发情表现后发情持续期变化较大,一般会持续3~14天,驴的排卵时间也会因卵巢上卵泡生长位置的差异,排卵时间也会出现较大差异,排卵时间多在发情的第7~10天,在发情停止前的12~24小时内排卵不等,这就造成了驴输精时间难以确定。传统技术是通过对卵巢的直肠触诊,在感觉到卵泡发育到卵泡柔软有弹性,具波动以后时实施输精,即直肠检查的第3期和第4期,但直肠触诊技术需要技术人员很长时间的经验积累,不同人对卵泡发育阶段的判断也存在差异,即使准确判定卵泡发育的阶段,也难以准确的确定排卵时间,3期的卵泡会维持1~3天,4期的卵泡也会持续1-3天,也难以确定排卵时间,这就造成了情期排卵难以控制,一次人工输精后受胎率不足30%,需要对驴多次人工输精才能提高受胎率。经试验,每二小时进行一次人工输精,连续操作1-3天,才能达到70%以上的受胎率;这样连续操作费时费力,是常规情况下难以做到的。
发明内容:
为了实现省时省力地提高驴人工授精的受胎率,本发明提出一种增加驴受胎率的鲜精人工授精方法。
本发明的目的是这样达到的:
一种增加驴受胎率的鲜精人工授精方法,其特征在于,它包括鲜精采集、消毒稀释处理过程和诱导排卵定时输精过程,具体是:
(一)鲜精采集、消毒稀释处理过程是,采用假阴道采集公驴的精液,精液经灭菌的4层消毒纱布过滤,除去胶冻,用肉眼观察原精液的颜色,正常精液色泽呈乳白、灰白色或淡黄色,取正常精液并记录原精液量,在配有38℃恒温装置的相差显微镜上评定活率,取活率≥70%的原精进行稀释;稀释按原精与稀释液1:1的体积比例等温稀释;稀释后的鲜精应在1小时之内对待孕母驴完成输精过程;
稀释液按以下成分配制:三羟基三甲基甲烷33—34g、柠檬酸8—9g、葡萄糖15—16g、甘油70—71mL、青霉素5万单位、链霉素5万单位:
(二)诱导排卵定时输精过程是,在驴出现发情表现后的第7~10天内,人工将直肠B超探头经驴直肠送至卵巢部位,通过调整直肠探头在卵巢部位的扫描面,检测卵巢上卵泡发育的大小尺寸,当发现卵泡直径达到3.4-3.5cm时,给驴注射300单位的促黄体素或绒毛膜促性腺素,使驴集中时间进行排卵,降低卵泡发育中闭锁的几率,并在排卵前10小时至排卵后6小时内、将消毒稀释处理的鲜精实施人工输精,输精剂量15mL,确保驴精子与驴卵子在具有受精能力的时间内相遇完成受精过程,使驴受胎。
本发明采用诱导排卵定时输精的技术措施,积极效果如下:
1、利用B超技术检测卵巢,可清晰见到卵泡的大小,与传统直肠触诊技术相比,便于技术人员掌握和技术推广,不需要长时间的经验积累和长时间培训,同时避免检测人员对卵泡发育阶段的误判,减少对传统直肠触诊技术的依赖。
2、在卵泡达到特定大小后利用激素处理,可以降低卵泡发育中闭锁的几率,同时卵泡发生排卵的时间相对比较集中,可以实现排卵后6小时内或排卵前10小时定时进行输精,减少了传统直肠触诊技术难以确定排卵时间的问题。
3、通过在规定时间内一次输精,可保障精子与卵子均在具有受精能力的时间内相遇完成受精,同时由于输精次数少,减少了母驴子宫的排异反应,可以在一定程度上提高受胎率,特别是冷冻精液受胎率。
下面是本发明与传统直肠触诊的方法实验效果效果对比:
从图中看出,采用本发明采用诱导排卵定时输精的技术措施,只需1次输精情期受胎率可达73.3%。
具体实施方式
本领域技术人员根据发明内容描述的鲜精采集、消毒稀释处理过程和诱导排卵定时输精过程即可实施,在此不再详细描述。
