摘　　要：【目的】调查乌鲁木齐市某牛场奶牛不孕症的发病情况,为不孕症综合防控措施的制定提供参考。【方法】通过直肠检查、B超探查对不孕症患病牛的发病原因进行记录分析。【结果】不孕症的发病率为11.83%(121/1022),其中子宫炎症占比23.14%(28/121),卵巢静止占比11.57%(14/121),卵巢囊肿占比9.09%(11/121),卵巢萎缩占比9.92%(12/121),子宫粘连占比8.82%(10/121),子宫肌瘤占比9.09%(11/121)及其他原因占比28.93%(35/121),其中子宫炎症不孕在7岁以后发病率最高,卵巢静止不孕在4~6岁发病率最高,卵巢囊肿不孕在1~9岁期间呈缓慢的上升趋势,卵巢萎缩不孕在9岁以后的发病率最高,子宫粘连不孕随奶牛年龄的增加,其发病率不断增高,子宫肌瘤不孕在7岁以后发病率最高。【结论】该牛场奶牛不孕症的发病率较高,主要以子宫疾病与卵巢疾病不孕为主,随着奶牛年龄及胎次的增加有所增加,防控中应密切关注引起子宫感染和卵巢疾病的因素。【Objective】To investigate the incidence of infertility in dairy cows in a farm in Urumqi and to provide reference for the development of comprehensive prevention and control measures.【Methods】The causes of infertility were recorded and analyzed by rectal examination and B-ultrasound probing.【Results】The incidence of infertility was 11.83%(121/1022),including 23.14%(28/121)for uterine inflammatory,11.57%(14/121)for ovarian quiescent,9.09%(11/121)for ovarian cystic,9.92%(12/121)for ovarian atrophic,8.82%(10/121)for uterine adhesions,9.09%(11/121)for uterine myomatous,and 28.93%(35/121)for other reasons.The incidence rates of uterine inflammatory and myomatous infertility were both highest after 7 years of age,that of ovarian quiescent infertility was highest from 4 to 6 years of age,and of ovarian atrophic infertility was 9 years of age,resovarian cystic infertility showed a slow increasing trend from 1 to 9 years of age,and uterine adhesion infertility increased with increasing age of the cow.【Conclusion】The incidence of infertility in the dairy farm was high,mainly caused by uterine and ovarian disease,which increased with the age of cows and the number of litters,hence close attention to the factors causing uterine infection and ovarian disease should be paid during its prevention and control.
