猪人工授精过程对母猪生产力影响的研究_动物论文

摘要：通过对A B两场人工授精均设对比试验组各项指标的影响因素研究实验证明1 有效精子数对母猪受胎率及产仔数有显著影响可以使受胎率提高3.7%左右，经t检验分析达到显著水平。人工授精的时间及次数对母猪繁殖性能影响也是显著的，对于每天2次发情鉴定持续发情一天的母猪来说2次输精比1次输精分娩率要高0.8%-2.6%。窝产仔数要提高0.2%-0.4%；对于持续发情2天以上的母猪来说输精2次以上比输精1次在分娩率上提高约3.1%窝产仔数提高0.78%，平均值差异显著。不同输精速度也影响这受胎率，实验证明在5-10min内输完精比1-3min内输完在受胎率产仔率要高。

Process of artificial insemination of pigs sow productivity study on the impact

Abstract: Through two artificial inseminations supposes contrast experiment group each target to A the B the influence factor research experiment to prove 1 effective sperm several pair of sow conception rates and bear young the number to have the remarkable influence to be possible to make the conception rate to enhance about 3.7%, achieves the remarkable level after the T-test analysis. The artificial insemination time and the number of times to the sow reproduction performance influence also are remarkable, regarding daily 2 times is in heat the appraisal to continue to be in heat a day-long sow 2 times to lose fine compared to 1 time loses the fine childbirth rate to want high 0.8%-2.6%.The nest bears young the number to have to enhance 0.2%-0.4%; Regarding continues to be in heat 2 days above sows to lose above the fine 2 times compared to lose fine 1 time enhances 3.1% nests in the childbirth rate to bear young the number to enhance 0.78% approximately, the mean value difference is remarkable. Loses the fine speed also to affect this conception rate differently, the experiment proved loses fine in 5-10min loses 1-3min in bears young in the conception rate must be higher than.

Key word: Artificial insemination: Is in heat the appraisal: Loses the fine quantity: Loses the sperm number: Loses the fine time: Loses the fine number of times: Childbirth rate: The nest bears young the number: Loses the fine speed

前言
在养猪集约化后最重要的技术就是人工受精。人工受精技术可以充分挖掘母猪生产潜力，充分利用优良公猪的潜在繁殖能力，加速家畜品种改良，控制某些疾病的发生利于提高母猪受胎效率，可以使公畜的精液不受时间及地域的限制，促进其它繁殖技术的发展［1］这里说的人工授精技术主要是鲜人工授精技术主要包括公猪的饲养管理公猪的调教采精精液品质检查精液的稀释及保存精液等关键技术环节。在实践生产当中人工授精受胎率的高低主要取决与精液品质、输精时间、输精技术和有效精子数量。近年来研究表明猪人工授精受孕率在90％以上，产仔率平均在8～12个,最多可达17～20个。与本交无明显差异［2］。目前我省上规模的养猪场使用人工授精技术还为数不多。随着国家政策对农业方面的倾斜在未来10到20年内回有很多规模化养猪场兴起，因此推广人工受精技术就成为一项紧迫的任务。因此在大同基业畜牧有限公司及榆次得天缘种猪场实习期间对人工受精技术的各个环节及操作技术要点做了系统的统计和分析并查阅了大量有关人工受精技术的书籍论文杂志.并做一些相关的实验验证其准确度及精确性.主要对输精时间次数输精量对母猪生产效率的影响做了细致的分析和总结。对提高规模化养猪场提高其经济效益推广人工授精技术有一定的意义！
