Abstract

The objective of this study was to identify risk factors for repeat breeder dairy cows and their impact on reproductive performance. The characteristics of 1,504 cows, including their peripartum health, nutrition, production, and reproduction, were collected. Cows with metabolic disorder were significantly more likely (odds ratio [OR], 2.47; p < 0.001) and cows with clinical endometritis tended to be more likely (OR, 1.35; p < 0.1) to become repeat breeders than cows without metabolic disorder and clinical endometritis, respectively. Cows initially inseminated > 80 days after calving were less likely (OR, 0.78; p < 0.05) to become repeat breeders than cows initially inseminated ≤ 80 days after calving. As a result, repeat breeding in dairy cows resulted in a 90 day longer (p < 0.0001) mean interval from calving to pregnancy. In conclusion, postpartum metabolic disorder, clinical endometritis, and a short interval from calving to initial insemination were risk factors for repeat breeder dairy cows, resulting in a severely impaired reproductive performance.
重复饲养奶牛的危险因素及其对繁殖性能的影响
本研究旨在确定重复种奶牛的危险因素及其对繁殖性能的影响。收集了1,504头奶牛的围产期健康、营养、生产和繁殖等特征。奶牛出现代谢紊乱的可能性显著增加(优势比[OR], 2.47;p < 0.001),奶牛出现临床子宫内膜炎的可能性更大(OR, 1.35;P < 0.1),分别比无代谢紊乱和临床子宫内膜炎的奶牛成为重复种牛。母牛在产犊后80天开始受精的可能性较低(OR, 0.78;P < 0.05)比产犊后≤80天初次受精的奶牛成为重复种牛。结果表明,重复育种使奶牛从产犊到妊娠的平均间隔延长了90天(p < 0.0001)。综上所述,产后代谢紊乱、临床子宫内膜炎、产犊至初始授精间隔过短是重复种奶牛繁殖性能严重受损的危险因素。
