Abstract

The Bachaur is a mediumized draft purpose breed which has been recognized by ICAR-National Bureau of Animal Genetic Resources (NBAGR) Karnal, India, and presently is on the verge of extinction. Since there are no data regarding the seminal parameters of this breed, this work was performed to evaluate seminal parameters of freshly ejaculated semen. A total of three healthy breeding Bachaur bulls aged 2.5-5 years were selected for the study which were maintained under identical managemental conditions. Semen parameters of these bulls were studied across 10 ejaculates. The average scrotal circumference and testicular weight of the three bulls were 27.78 ± 1.2 cm and 400.67 ± 26.6 g, respectively. The average overall volume (mL), pH, concentration (million/mL), liveability (%), abnormality (%), HOST (%) and acrosome integrity (%) were 2.20 ± 0.19, 6.86 ± 0.06, 1245.60 ± 23.49, 85.09 ± 0.91, 4.13 ± 0.06, 81.16 ± 1.18 and 83.54 ± 1.32, respectively. The average overall mass motility of three Bachaur bulls was 3.57 ± 0.06 in 0-5 scale and individual motility averaged 84.78 ± 1.70 per cent. The volume of ejaculates in Bachaur bull seemed to be lower as compared to other exotic and Indian breeds. However, the semen parameters with regard to mass motility, liveability, abnormalities, hypo-osmotic swelling test (HOST) and acrosomal integrity seemed similar to other exotic and Indian breeds.

巴夏尔公牛精液的特点。

Bachaur 是一种中型草食性品种，已获得印度卡纳尔 ICAR 国家动物遗传资源局 (NBAGR) 的认可，目前濒临灭绝。由于没有关于该品种精液参数的数据，因此本研究对新鲜射出精液的精液参数进行了评估。研究共选取了三头健康的巴夏尔种公牛，年龄在 2.5-5 岁之间，并在相同的管理条件下饲养。研究了这些公牛 10 次射精的精液参数。三头公牛的平均阴囊周长和睾丸重量分别为 27.78 ± 1.2 厘米和 400.67 ± 26.6 克。平均总体积（毫升）、pH值、浓度（百万/毫升）、活率（%）、畸形率（%）、HOST（%）和顶体完整性（%）分别为 2.20 ± 0.19、6.86 ± 0.06、1245.60 ± 23.49、85.09 ± 0.91、4.13 ± 0.06、81.16 ± 1.18 和 83.54 ± 1.32。在 0-5 级中，三头巴夏尔公牛的平均总运动量为 3.57 ± 0.06，单个运动量平均为 84.78 ± 1.70%。与其他外来品种和印度品种相比，巴夏尔公牛的射精量似乎较低。然而，精液的质量运动性、活率、异常、低渗膨胀试验（HOST）和顶体完整性等参数似乎与其他外来品种和印度品种相似。

期刊介绍： The journal offers comprehensive information concerning physiology, pathology, and biotechnology of reproduction. Topical results are currently published in original papers, reviews, and short communications with particular attention to investigations on practicable techniques. Carefully selected reports, e. g. on embryo transfer and associated biotechnologies, gene transfer, and spermatology provide a link between basic research and clinical application. The journal applies to breeders, veterinarians, and biologists, and is also of interest in human medicine. Interdisciplinary cooperation is documented in the proceedings of the joint annual meetings. Fields of interest: Animal reproduction and biotechnology with special regard to investigations on applied and clinical research.
