乳用伊犁马牧食行为初步研究

2013年8月至10月,采用跟踪观察法,在昭苏马场草甸草原上研究了放牧条件下乳用伊犁马的牧食行为.结果表明,在15h放牧时间观测中,乳用伊犁马各主要行为的总体时间分配顺序是：休息＞采食＞游走＞挤奶＞其他＞饮水;在8月、9月、10月其休息时间依次占总观测时间的55.92％,58.10％,56.49％,采食时间依次占总观测时间的33.01％,34.39％,38.37％;不同观察月份间乳用伊犁马的牧食行为存在显著差异（P＜0.05）,从8月到10月乳用伊犁马采食时间显著增加、游走时间显著减少（P＜0.05）,休息、饮水时间变化不显著（P＞0.05）;不同观察月份间,乳用伊犁马在近14 h的观测时间中行走距离也存在一定差异,8月、9月、10月依次为（5.61±0.19）,（6.96±1.08）,（10.90±0.99） km.

Preliminary Studies on Grazing Behavior of Yili Horses Raised for Milk

Using following-observing method, grazing behavior of Yili horses raized for milk in Zhaosu horse ranch was studied under grazing condition from August to October 2013.The results showed that in 15 hours of grazing time observation,the overall time distribution order of Yili horses raised for milk were as follows ： rest〉intake〉 migration〉 milk〉 walk〉 drinking. In August, September, October, the break in turn accounted for 55.92%,58.10%,56.49% of the total observation time,feeding time,in turn,33.01%, 34.39 % and 38.37 % of total observation time; In different month, there were signifieant differences in repect of grazing behavior of Yili horses raised for milk from August to October feeding time of Yili horses raised for milk increased significantly, migration time significantly reduced （P 〈0.05）, change of rest, drink time was not significant （P 〉0.05） ;In observation of nearly 14 d,there existed a certain differences in walking distance.In August,September,October the order are as follows： （5.61±0.19） km, （6.96±1.08） kin, （10.90±0.99） km.
