| 摘 要： | 本次试验对15头中国荷斯坦泌乳牛的行为表现逐头进行12 h观察,并按不同泌乳阶段分三组:A组(泌乳前期)、B组(泌乳中期)、C组(泌乳后期)进行分析,每组均为5头。结果表明:泌乳前期牛的咀嚼次数和每次低头连续采食饲料次(口)数最多,早晨饲喂以后反刍来临时间和咀嚼时间最长,反刍咀嚼速度及每次低头采食频率快。泌乳中期试验牛的昼间反刍时间、昼间反刍时间占昼的时间、每次低头采食时间及每口饲料咀嚼时间都较长。泌乳后期试验牛的昼间反刍周期数较多,食团的吞咽至下一食团的逆呕间隔时间和站立时间均较长。

| Abstract: | Fifteen China Holstein cows were divided into 3 groups according to lactation period including group A(earlier lactation),group B(middle lactation),and group C(late lactation) to observe the behavior for 12 hours.The results showed that chewing frequency and number of continuous eating were higher for group A with the long rumination time and fast speed of ruminating and eating after morning feeding;cows at the middle lactation period showed a longer time of ruminating in the day time,higher proportion of ruminating in the day time,longer eating time per feeding and chewing time;cows at the late lactation demonstrated more ruminating cycle,longer standing time and interval between swallow and vomit a conglomeration. |
