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.
摘要:
Bachaur是一种媒介化的目的品种,已被ICAR-国家动物遗传资源局(NBAGR)Karnal认可,印度,目前正处于灭绝的边缘。由于没有关于该品种的开创性参数的数据,进行这项工作是为了评估新鲜射精精液的精液参数。总共选择了三只2.5-5岁的健康繁殖Bachaur公牛进行研究,这些公牛在相同的管理条件下保持。在10只射精中研究了这些公牛的精液参数。三头公牛的平均阴囊围和睾丸重量分别为27.78±1.2cm和400.67±26.6g,分别。平均总体积(mL),pH值,浓度(百万/mL),宜居性(%),异常(%),宿主(%)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量表中,三头Bachaur公牛的平均总体运动能力为3.57±0.06,个体运动能力平均为84.78±1.70%。与其他异国情调和印度品种相比,Bachaur公牛的射精量似乎较低。然而,关于质量运动性的精液参数,宜居性,异常,低渗肿胀试验(HOST)和顶体完整性似乎与其他外来和印度品种相似。
