B超声像技术在奶牛场繁殖工作中的应用

Application of B-ultrasound Imaging Technology in Breeding Work of Dairy Farm

目前B超声像技术(简称“B超”)在奶牛场的繁殖工作中有着不可替代的作用。本文介绍了B超的基本原理以及奶牛场直肠检查和B超在奶牛早期妊娠诊断上的基本应用方法。B超可以较为准确地判断出胚胎的不同妊娠天数,并且可以进行奶牛产后子宫疾病的检查,从而做出准确的诊断,B超还可以针对卵巢的不同回声状态来对卵巢静止、卵泡囊肿、黄体囊肿以及持久黄体等卵巢情况进行判断;可以配合直肠检查法,有效地提高奶牛早期妊娠诊断率和生殖系统疾病的诊断率。

At present,B-ultrasound imaging technology(short for B-scan)plays an irreplaceable role in the breeding work of dairy farms.This paper introduced the basic principle of B-scan and the basic application methods of rectal examination and B-scan in the early pregnancy diagnosis of dairy cows.B-scan can more accurately judge the different gestation days of embryos,and can check postpartum uterine diseases of dairy cows,so as to make accurate diagnosis.B-scan can also judge ovarian conditions such as ovarian stasis,follicular cyst,luteal cyst and persistent luteal body according to different echo states of the ovary.It can be combined with rectal examination to effectively improve the early pregnancy diagnosis rate and reproductive system disease diagnosis rate of dairy cows.
