便携式B超在母猪早期妊娠诊断中的应用研究

Abstract

Abstract: 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.

Key words: B ultrasonic diagnostic techniques; early pregnancy diagnosis; sow; fecundity
