摘　　要：为了研究不同产犊季节和胎次对荷斯坦牛部分繁殖指标的影响,为长江中下游地区荷斯坦牛合理安排配种时间提供科学依据。本试验利用海丰奶牛场引进的澳系荷斯坦牛的繁殖指标数据,分析了产犊季节和不同胎次对部分繁殖指标的影响。结果显示,产犊季节对产后第一次发情泌乳天数、配种指数、产后受孕天数以及产犊间隔等繁殖指标的影响达到极显著水平(P<0.01)。胎次对发情泌乳天数、产后受孕天数以及产犊间隔等繁殖指标的影响也达到极显著水平(P<0.01)。在本研究中,秋季产犊的奶牛繁殖指标最佳。此外,头胎产犊奶牛的繁殖性能在各胎次中最好,该结果对同类地区荷斯坦牛繁殖管理有很好的指导作用。In order to study the impact of the of different calving season and parity on the part ot me reprooucnve indicators of Holstein cows, to provide a scientific basis for reasonable arrangements for the middle and lower reaches of the Yangtze River Holstein cows breeding time. Use the dairy cattle breeding index data of Haifeng dairy farm, which imports 8 129 Holstein cows from Australia to analyze the impact of the calving season and parity on the part of the breeding indicators. Calving season highly significant affect on the days of lactation after parturition, breeding index, number of days postpartum conception breeding and calving interval （P〈0.01）. Parity also highly significant affect on the days of lactation after parturition, breeding index, number of days postpartum conception breeding and calving interval （P〈0.01）. In the present study, cows calving in autumn have best breeding indicators. In addition, the first-born reproductive performance of cows calving parities best, the results can be a good guide of the Holstein cattle breeding management in similar areas.
