| 摘 要： | 对4只4×4拉丁方设计中的绵羊，分别用PEG（聚乙二醇）和CrEDTA（乙二胺四乙酸铬）两种液相标记物同时测定了瘤胃液稀释率和瘤胃液体积。结果表明，两种方法测得的瘤胃液稀释率之间或瘤胃液体积之间存在极显著（P＜0．01）或显著（P＜0.05）相关关系。但用两种方法测得的瘤胃液稀释率或瘤胃液体积之间差异极显著（P＜0．01）或显著（P＜0．05）。用PEG法测得的两指标均高于用CrEDTA法测得的结果。

| Abstract: | PEG and CrEDTA were used as rumen liquid markers to measure rumen liquid dilutionrate and rumen liquid volume of the rumen fluid of sheep in a 4 x 4 Latin square design.Results showed that there was significant correlation between dilution rate (P < o- o1) orvolume (P <0.05) measured by PEG and CrEDTA. However, the dilution rate or volumemeasured by PEG were significantly higher than those measured by CrEDTA, respectively(P<0.01, P<0.05). |
