| 摘 要： | 运用B-型超声波仪观察了自然发情的6头河流型母水牛和6头沼泽型母水牛的卵泡发育动态,发现河流型母水牛的发情周期由2个卵泡发育波组成;沼泽型母水牛以2个卵泡发育波为主(66.7%,4/6)。河流型水牛2个卵泡波分别在发情周期的第1.3、12.2天出现,其第1波征集、选择卵泡数分别为14.8和2.5个,第2波分别为14.2和3.2个;沼泽型水牛2个卵泡波分别在发情周期的第1.1、11.0天出现,其第1波征集、选择卵泡数分别为8.0和1.0个,第2波分别为7.8和1.5个。以上数据的各波征集卵泡数和选择卵泡数中,河流型水牛和沼泽型水牛之间差异显著(P0.05)。

| Abstract: | The objective of this study was to investigate the follicular dynamics by B-mode ultrasonography during spontaneous estrous cycles in 6 river buffaloes and 6 swamp buffaloes. 2 patterns of follicular waves were discovered in one estrous cycle in river buffaloes, and 2 follicular waves were the most frequent (66.7%, 4/6) in swamp buffaloes. During the two patterns of follicular waves, the 1st and 2nd wave of river buffaloes emerged on 1.3 and 12.2 d，respectively, and swamp buffaloes emerged on 1.1 and 11.0 d. The number of recruited and selected follicles in 1st wave was 14.8, 2.5 d, and 2nd wave was 14.2, 3.2 d in river buffaloes, while 1st wave was 8.0, 1.0 d, and 2nd wave was 7.8, 1.5 d in swamp buffaloes. There were significant differences between river buffaloes and swamp buffaloes(P<0.05) in the number of follicles recruited and the number of follicles selected. |
