Abstract

本发明涉及一种母兔受精方法,其具体方法为,输精时将经过消毒的输精器吸上优质精液,由助手保持母兔呈自然站立或伏卧姿势,术者用左手提起尾部,右手将输精器靠背部方向慢慢插入阴道6~7厘米深处,慢慢注人精液,每兔输入0.2~0.8毫升。上述母兔受精方法中,需要有熟练的操作技术和必要的设备,其中,主要器材和药品为采精器、集精瓶、输精器。本发明采用人工授精,通过人工采取公兔的精液,经品质检查、稀释后,再输入到母兔生殖道内,使其受胎,其优点在于能充分利用优良种公兔,提高兔群质量,迅速推广良种,还可减少种公兔的饲养量,降低饲养成本;减少疾病传播;克服某些繁殖障碍,便于集约化生产管理。

Description

一种母兔的受精方法
技术领域
本发明涉及一种母兔的受精方法,属于动物饲养技术领域。
背景技术
家兔是由一种野生的穴兔经过驯化饲养而成的。兔科(Leporidae)。家兔是草食性动物,以野草、野菜、树叶、嫩枝等为食,多为白色、灰色与黑色。喜欢独居,白天活动少,都处于假眠或休息状态,多在夜间活动,食量大。有啃木、扒土的习惯。胆小怕惊、怕热、怕潮,喜欢安静、清洁、干燥、凉爽的环境,不能忍受肮脏的环境。繁殖力强、多胎多产、孕期短、成熟早(4-5个月)。
发明内容
本发明的目的在于提供一种母兔受精方法,以便更好地改善母兔受精处理效果。
为了实现上述目的,本发明的技术方案如下。
一种母兔受精方法,其具体方法为,输精时将经过消毒的输精器吸上优质精液,由助手保持母兔呈自然站立或伏卧姿势,术者用左手提起尾部,右手将输精器靠背部方向慢慢插入阴道6~7厘米深处,慢慢注人精液,每兔输入0.2~0.8毫升。
进一步地,上述母兔受精方法中,需要有熟练的操作技术和必要的设备,其中,主要器材和药品为采精器、集精瓶、输精器,其中,采精器为外壳长12~14厘米的硬塑或胶管,长为外壳的两倍;输精器为2毫升注射器。
进一步地,该方法中,需要注意以下事项:
(1)要求精液品质良好:要想获得理想的配种效果,必须有品质良好的精液,只有经过镜检确认品质良好的精液才能用于输精。
(2)严格消毒:在人工授精过程中使用的所有器具、药品都必须清洗干净,严格消毒;
(3)正确选用促排卵激素:兔为刺激性排卵动物,发情后不经交配或药物刺激是不会排卵的,因此,在输精前必须刺激母兔排卵;一般选用绒毛膜促性腺素、黄体素等促排激素刺激排卵;对未发情的母兔可用孕马血清促性腺素、雌二醇等诱导发情,然后再刺激排卵;一般促排激素在输精前0.5-1.0小时给母兔注射,亦可在输精后即刻注射。
(4)输精部位准确:母兔膀胱在阴道内约5~7厘米处的腹面开口,大小与阴道腔孔径相当,而且在阴道下面与阴道平行,在输精时,易将输精管误插入排尿口,而将精液输入膀胱;如输精管插入过深又易将精液输入一侧子宫,造成另一侧空怀。因此,在输精时,先应将输精器朝向阴道背壁插入约6~7厘米深处,越过尿道口后再转向腹面,直至插入8-10厘米深处的子宫颈口附近,边输边退,使精子自子宫颈能同时进入两个子宫内,有利于提高受胎产仔数。
该发明的有益效果在于:本发明采用人工授精,通过人工采取公兔的精液,经品质检查、稀释后,再输入到母兔生殖道内,使其受胎,其优点在于能充分利用优良种公兔,提高兔群质量,迅速推广良种,还可减少种公兔的饲养量,降低饲养成本;减少疾病传播;克服某些繁殖障碍,如公母兔体型差异过大等,便于集约化生产管理。
具体实施方式
下面结合实施例对本发明的具体实施方式进行描述,以便更好的理解本发明。
实施例
本实施例中的母兔受精方法,其具体方法为,输精时将经过消毒的输精器吸上优质精液,由助手保持母兔呈自然站立或伏卧姿势,术者用左手提起尾部,右手将输精器靠背部方向慢慢插入阴道6~7厘米深处,慢慢注人精液,每兔输入0.2~0.8毫升。
上述母兔受精方法中,需要有熟练的操作技术和必要的设备,其中,主要器材和药品为采精器、集精瓶、输精器,其中,采精器为外壳长12~14厘米的硬塑或胶管,长为外壳的两倍;输精器为2毫升注射器。
该方法中,需要注意以下事项:
(1)要求精液品质良好:要想获得理想的配种效果,必须有品质良好的精液,只有经过镜检确认品质良好的精液才能用于输精。
(2)严格消毒:在人工授精过程中使用的所有器具、药品都必须清洗干净,严格消毒;
(3)正确选用促排卵激素:兔为刺激性排卵动物,发情后不经交配或药物刺激是不会排卵的,因此,在输精前必须刺激母兔排卵;一般选用绒毛膜促性腺素、黄体素等促排激素刺激排卵;对未发情的母兔可用孕马血清促性腺素、雌二醇等诱导发情,然后再刺激排卵;一般促排激素在输精前0.5-1.0小时给母兔注射,亦可在输精后即刻注射。
(4)输精部位准确:母兔膀胱在阴道内约5~7厘米处的腹面开口,大小与阴道腔孔径相当,而且在阴道下面与阴道平行,在输精时,易将输精管误插入排尿口,而将精液输入膀胱;如输精管插入过深又易将精液输入一侧子宫,造成另一侧空怀。因此,在输精时,先应将输精器朝向阴道背壁插入约6~7厘米深处,越过尿道口后再转向腹面,直至插入8-10厘米深处的子宫颈口附近,边输边退,使精子自子宫颈能同时进入两个子宫内,有利于提高受胎产仔数。
以上所述是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也视为本发明的保护范围。
