The study was conducted at Artificial Breeding Research Centre, NDRI, Karnal, to determine the sexual behavior and its relationship with semen quality parameters in Sahiwal breeding bulls.
A total of 63 ejaculates were collected from six adult Sahiwal bulls (age ~47 mo and bwt ~466 kg), to study the relationship of sexual behavior and semen quality. The degree of association between different variables was estimated by Pearson's correlation coefficient method.
The results depicted that, sexual aggressiveness showed significantly high positive correlation with libido score (LS) and sexual behavior score (SBS). Reaction time (RT) and total time taken in mounts (TTTM) had a significant negative correlation with LS and SBS. Penile erection score and penile protrusion score (PPS) both had a significant positive correlation with ejaculatory thrust score, mating ability score, and SBS. Results of correlation among seminal attributes and with sexual behavior depicted that ejaculate volume had positive significant correlation with initial progressive motility (IPM), sperm concentration (SCON), head abnormality, total abnormality, hypo-osmotic swelling test (HOST), acrosomal integrity (AI) whereas, mass activity had positive significant correlation with IPM, SCON, non-eosinophilic spermatozoa count (NESC), HOST, AI, RT and TTTM and IPM had positive significant correlation with SCON, NESC, HOST, AI, and TTTM, whereas and HOST had positive significant correlation with AI. Among seminal attributes, SCON had a positive significant correlation with PPS where as head abnormalities had a positive significant correlation with RT and TTTM.
It can be concluded that the relationship of sexual behavior and semen quality parameters are reflecting that the sexual behavior of individual bulls is important to harvest good quality and quantity of semen as desired type of sexual preparation can be provided.
本研究在卡纳尔国家动物研究所人工繁育研究中心开展，旨在确定萨希瓦尔种公牛的性行为及其与精液质量参数的关系。
从6头成年萨希瓦尔公牛（年龄约47个月，体重约466千克）采集了共计63份精液样本，以研究性行为与精液质量的关系。采用皮尔逊相关系数法估计不同变量之间的关联程度。
结果表明，性攻击性与性欲评分（LS）和性行为评分（SBS）呈显著高度正相关。反应时间（RT）和总爬跨时间（TTTM）与LS和SBS呈显著负相关。阴茎勃起评分和阴茎伸出评分（PPS）与射精推力评分、交配能力评分和SBS均呈显著正相关。精液特性与性行为之间的相关性结果表明，射精量与初始前进运动率（IPM）、精子浓度（SCON）、头部异常、总异常、低渗肿胀试验（HOST）、顶体完整性（AI）呈显著正相关；而活力与IPM、SCON、非嗜酸性精子计数（NESC）、HOST、AI、RT和TTTM呈显著正相关；IPM与SCON、NESC、HOST、AI和TTTM呈显著正相关；HOST与AI呈显著正相关。在精液特性中，SCON与PPS呈显著正相关，而头部异常与RT和TTTM呈显著正相关。
可以得出结论，性行为与精液质量参数之间的关系反映出，个体公牛的性行为对于获取高质量和高数量的精液很重要，因为可以提供所需类型的性准备。
