两种测定水牛瘤胃体积和周转率方法的比较

COMPARASION BETWEEN TWO METHODS TO DETERMINE VOLUME AND TURNOVER RATE OF BUFFALO′S RUMEN

试验采用４头装有永久性瘤胃瘘管的本地雄性水牛，在秋末冬初自由采食稻草日粮条件下比较ＰＥＧ一次灌注法与Ｃｒ－ＥＤＴＡ连续灌流法在测定水牛瘤胃液体积、周转率、停留时间方面的差别。结果表明，两种方法无明显差异。

The purpose of this study is to compare the differences between PEG infused once and Cr EDTA infused continuously with regard to determining fluid volume, turnover rate and retention time of buffalo′s rumen. Four native male buffaloes with permanent rumen fistulae were used in this experiment under a condition of being fed with rice straw in the end of autumn and the beginning of winter. The result shows no significant difference between two methods.
