绵羊同期发情技术研究
摘要
为了促进兵团养羊业的快速发展,提高养羊业的经济效益,在《兵团工厂化高效养羊科技示范建设项目》的支持下,本人主要研究在兵团南北疆绵羊繁殖季节进行同期发情处理的全过程,重点对公羊的生殖保健、绵羊的同期发情及人工授精技术方面进行了探索,建立了一整套的操作规程。
本试验提出公羊生殖保健的方案:对性欲正常、精液品质低下的公羊肌注丙酸睾丸素、V_E、PMSG、LRH—A_3,对性欲低下、精液品质正常的公羊肌注丙酸睾丸素、V_E、HCG、LRH—A_3;同时进行睾丸热敷、按摩。实验结果证实:经过以上激素处理,对性欲正常、精液品质低下的公羊有效率为98.5%(66/67),对性欲低下、精液品质正常的公羊有效率为95%(57/60),取得了显著的试验结果(P＜0.01)。
本试验在山区牧场进行绵羊同期发情处理的方法:母羊标记→埋植CIDR,同时肌肉注射复合孕酮制剂1ml→埋植12d→撤栓,同时肌肉注射孕马血清促性腺激素500IU→撤栓后48—56h配种,同时静脉注射绒毛膜促性腺激素300IU→精液用催产素和LRHA_3处理→公羊补配2个情期。实验结果证实:同期发情母羊的情期受胎率平均为80.48%,繁殖率达到127.6%,同期发情技术可以提高山区牧场绵羊的繁殖率(P＜0.05)。
本试验在农区团场全舍饲条件下进行绵羊同期发情处理,方法同上。实验结果证实:母羊繁殖率达到160%,羔羊成活率为98%,生长期内平均日增量293.6g,4月龄平均体重达到30.12kg。
本试验选择1016只产后20天的1—5岁母羊进行同期发情处理。试验分为四组,每组之间采取不同的激素处理方法进行试验处理。试验结果证实:各试验组的繁殖率平均在120%以上。
通过上述试验证明,在兵团南北疆,采用以上方法对绵羊进行同期发情处理,能够提高绵羊的繁殖率,有利于绵羊一年两产或两年三产高频繁殖目标的实现,使养羊业向“订单农业”发展,进而提高养羊的经济效益,促进兵团养羊业的快速发展。
The issue of research is whole process of estrus contral technique on breeding season sheep in corpe of Xinjiang.My emphasis are on reproduction health protectio n of ram,estrus contral of sheep and artificial insemenation,finally,we established a set of operating regulations in this field.The purpos is to raising economic effeci ency of sheep induatry,it can give birth to rapid development of sheep industry in c orpe of Xinjiang.
This study launched a program:inject propionic acid testosterone,V_E,HCG and LRH-A_3 to ram whose semen quality is nomal but whose sexual ablity performance d badly;inject propionic acid testosterone,V_E,PMSG and LRH-A_3 to ram whose se men quality is below the nomal but whose sexual ablity performanced well,at same time warm and massage the testicle.The result of the study can be proved that the effenciency is 98.5%among those ram whose semen quality is below the nomal but whose sexual ablity performanced well;conversely,to other sublects,its rate i s 95%.
The experiment method in mountain area:mark ewe-bury CIDR,inject combined pregnant hermone 1ml→wait 12 days→take off,inject PMSG 500IU→breed after tak e off 48-56 hours,inject HCG 300IU→samen oxytocin and LRHA_3→extra breedi ng in two estrus.We can make a conclusion:simultanous oestrus can raise the repro ductivity of sheep in mountain area.The contraled group,its average pregnancy rate is 80.48%,total reproductivity rate is 109.4%.There is no evdent difference between contraled group and non-contraled in some performanes of birth weight and wean weight of lamb.Another experiment was done under indoor condition by the same t reatment.Its result:reproductivity rate is 160%,lamb livability 98%,average increased weight per day is 293.6g,average weight at four months is 30.12kg.
This sthdy is that selected 1016 sheep at one to five borns of simnltaneous est rus reation at post-parturient in 20 days.It was four groups,per groups among deal with methods is different hormones.Its result:every groups's fertility above 120%.
It can be proved from this study that we can enhance sheep reproductivity by using simultaneous estrus technique,so we can deduce the pssibality of two lambs p er year and three lambs during two years.If we can realize this,it can give us a opportunity to develop "order agriculture",as a result,not only can it raise effencie ncy of sheep industry,but can promote rapid development of sheep industry of corpe
