摘要
通过对肃南鹿场的实地观察与统计分析,甘肃马鹿的发情季节主要在 10～11 月份,有明显发情特征,发情持续期多为 18h 左右,发情周期平均为(18.22±2.26)d,情期受胎率 65.52 %,总受胎率 63.83 %;分娩盛期在 6月下旬至 7 月上旬,妊娠天数 237～267 d,产仔率 59.57 %,繁殖成活率 51.77 %。
The basic situation of Gansu wapiti was observed at the Sunan deer farm. The results of reproductive characteristics were reported and analyzed in this paper. The wapiti had obvious estrous behavior, and began to conceive between October and November every year, its estrous cycle was 18.22±2.26 with about 18 hour of estrus period, 65.52 % of non-return estrous rate and 63.83 % of total conception rate.
