摘要
在拥有300头基础母猪的种猪场,利用直观、快速、准确和无损伤的便携式兽用B超仪抽样检测91头配种16 d以上的母猪在20与50 d的妊娠率。结果表明,18~20 d确诊的非妊娠准确率为100%,40~50 d确诊的妊娠准确率为100%;根据诊断结果对妊娠、疾病、返情、未妊娠不返情的母猪采取护理、治疗、补配和催情等措施,减少了母猪个体与群体的非生产天数。本试验建立了一种简单、快速、准确的母猪B超早期妊娠诊断技术,该技术可提高母猪个体及群体的繁殖力及猪场的经济效益。
The pregnancy rates at 20 and 50 days were tested by sampling 91 hybridization sows more than 16 days using the intuitive, fast, accurate and non-invasive portable veterinary B ultrasound instrument in the pig breeding farm had 300 sows. The results showed that the nonpregnant diagnostic accuracy rate was 100% at 18 to 20 days, and the pregnant diagnostic accuracy rate was 100% at 40 to 50 days. According the diagnostic results, the pregnancy, disease, estrus, nonpregnancy and non-estrused sows were took the appropriate measures such as nursing, treatment, supplementary breeding and sensuality, the non-productive days of the individuals and groups of sows were improved by above measures. The study built a intuitive, fast, accurate sows early pregnancy diagnosis technology, which improved the fertility of the individuals and groups of sows increased the economic benefit of pig farm.
