种公牛感染温氏枝原体后的生殖健康检测研究（英文）

目的]研究种公牛感染温氏枝原体后的生殖健康。方法]通过血常规和生殖健康检测等方法对药物治疗前后种公牛的血液和精液品质进行试验研究。结果]在未给予磷酸伯氨喹治疗前,病牛有轻度的贫血,血液涂片中可见大量的温氏枝原体;病牛阴囊壁肿大,睾丸变软,精液品质下降,精子活力降低,初级和次级畸形的精子比例增大;药物治疗后,温氏枝原体很快从血液中消失,临床症状逐渐缓解,顺利通过了1个月后生殖健康检测。结论]该研究为进一步研究温氏枝原体与公牛生殖机能下降之间的关系奠定了基础。

Breeding Soundness Examination of Breeding Bull after Infecting Mycoplasma wenyonii

Objective] The research aimed to study the reproductive health of breed- ing bull after infecting Mycoplasma wenyoniL Method] The blood and semen quality of breeding bull before and after drug treatment was studied by the methods of blood routine examination and breeding soundness examination （BSE）. Result] Be- fore the treatment with primaquine phosphate, slight anaemia was seen in diseased bull and a lot of M.wenyonfi were seen on blood smears. The scrotal wall of dis- eased bull swelled, testis was softened, the semen quality was reduced, semen quality was decreased and the proportion of primary and secondary deformed sperms was increased. After drug treatment, M.wenyonfi quickly disappeared from blood and the clinical systems were gradually alleviated, so BSE of breeding bulls after one month was passed. Conclusion] The research laid the foundation for fur- ther study on the relationship between M.wenyonfi and the reduction of bull＇s repro- ductive functions.
