摘要
The objective of this study was to assess the effect of non-genetic factors on semen characteristics of 22479 ejaculates from 139 Murrah bulls during the period of 2017-2020 analyzed under tropical conditions, maintained and recorded at Frozen Semen Bank (FSB), Bassi, Rajasthan Cooperative Dairy Federation, Jaipur, Rajasthan, India as well as in Information Network for Animal Productivity & Health ( INAPH) application maintained at National Dairy Development Board (NDDB). Results were recorded as 2.94 +/- 0.03 mL for volume, 1234.72 +/- 13.51 million/ mL for sperm concentration and 68.44 +/- 0.25 percentage for motility. Statistical analysis presented a significant difference for all semen parameters with studied non-genetic factors except semen collector for motility traits. Also, seasonal dynamics presented winter as the most suitable season for semen collection under tropical conditions. Season of ejaculates was observed as most influencing factors for all semen characteristics in Murrah bulls. Age of bull showed significantly increased values for all semen traits with the increasing age of bull except motility traits. Data analysis in this regard may be utilized to enhance the fertility rate by increasing the semen quality.
