AIM
The present study was carried out to compare the associated role of micro minerals and hormones in repeat breeding animals with the normal crossbred cows.
MATERIALS AND METHODS
Blood samples were collected from 10 normal cycling and 10 repeat breeding crossbred cows of Ramakrishna Mission Ashram, Narendrapur to study the plasma mineral profile and hormonal activities.
RESULTS
Zn was found to be highly significant (p<0.01) between the two groups. Follicle stimulating hormone (FSH) and progesterone showed significant (p<0.05) difference in repeat breeding animal from the normal cyclic animal, whereas no significant differences were observed in Ca, P, Cu, Se, Co, luteinizing hormone and estradiol level.
CONCLUSION
It may conclude that repeat breeding condition of crossbred cows in farm condition is mainly due to the low level of progesterone, FSH and zinc.
目的
开展本研究以比较微量矿物质和激素在重复配种动物与正常杂交奶牛中的相关作用。
材料与方法
从纳伦德拉布尔罗摩克里希那传道会静修所的10头正常发情和10头重复配种杂交奶牛采集血样，以研究血浆矿物质概况和激素活性。
结果
发现两组之间锌含量差异极显著（p<0.01）。重复配种动物的促卵泡激素（FSH）和孕酮与正常发情动物相比有显著差异（p<0.05），而钙、磷、铜、硒、钴、促黄体生成素和雌二醇水平未观察到显著差异。
结论
可以得出结论，农场条件下杂交奶牛的重复配种情况主要是由于孕酮、FSH和锌水平较低。
