摘要
卵巢囊肿是引起奶牛不孕的主要疾病之一,淘汰率很高。应用激素治疗难孕牛或超排牛也经常继发该病。发生卵巢囊肿原因很多,很难界定,但多与营养和激素因素有关。有些奶牛第一产后就不发情或久配不孕。如不及时治疗很可能转为慢性卵巢囊肿,最终只能淘汰。卵巢囊肿可分为卵泡囊肿和黄体囊肿。病因确切原因尚不完全清楚。目前认为,卵巢囊肿可能与内分泌机能失调、促黄体素分泌不足、排卵机能受到破坏有关。根据对一些县镇养牛小区中患不孕症奶牛的调查、直检及解剖诊断的统计,卵巢囊肿病例占总检数的16.70%,持久黄体占总检数的13.90%,卵巢静止、萎缩占总检数的6.94%.上述各类病症有单发的,也有多种病症同时存在的。这些疾病如不及时治疗,即使发情,也不能受精。本文主要介绍由卵泡囊肿移行黄体囊肿的一头荷斯坦奶治疗以前的状况和治疗以后的主要变化。
