B超诊断技术在德宏奶水牛繁殖上的应用与探索OA

To explore the reproductive application effect of B-ultrasound diagnostic technology on Dehong Dairy buffalo,a portable veterinary B-ultrasound device was used to conduct early pregnancy diagnosis for 302 cows and to screen for reproductive disorders for 59 Dehong Dairy buffalo,respectively.The results showed that the pregnancy in cows could be diagnosed by B-ultrasound images after 23 days of insemination,which was 37 days earlier than the rectal palpation method.The diagnosis rates of early pregnancy at 22-30 days,31-45 days,and 46-60 days after insemination were 84.9％,95.6％,and 100.0％,respectively,significantly higher than the values of 8.2％,62.9％,and 88.7％for the rectal palpation method.With the use of B-ultrasound diagnosis,a total of 19 cows with reproductive disorder diseases from a total of 59 cows were initially found,and 9 cows were cured and became pregnant after insemination,with a cure rate of 47.4％.The results indicate that the use of B-ultrasound diagnostic technology can improve the accuracy of early pregnancy diagnosis in cows and contribute to the screening and treatment of reproductive disorders in Dehong Dairy cows.
