摘要/Abstract

摘要： 选用两个肉牛消化代谢试验所测定的8个不同日粮有机物消化率，对比分析全收粪法、Cr₂O₃法、AIA法对所测定有机物消化率的影响。结果表明：用全收粪法、Cr₂O₃法、AIA法测定日粮有机物的表观消化率分别为67.43%、62.93%、72.15%，其中AIA法测定值显著高于Cr₂O₃法（P<0.05），外源指示剂Cr₂O₃在粪中回收率为90.74%，内源指示剂AIA回收率为118.17%。

Abstract: The objective of the experiment was to evaluate the efficacy of direct collection feces, Cr₂O₃ and AIA to predict OM digestibility (OMD) of diets. Four Simmental crossing steers and four Holstein steers in two experiments were respectively assigned randomly to feed alfalfa, hay, concentrate diets in a replicated 4×4 Latin square design to estimate OMD of eight different diets All feces were collected during wk 1. The OMD evaluated with the Cr₂O₃ method were significantly lower to compare with the AIA method, and the OMD determined with the direct collection feces were not statistically significant difference with Cr₂O₃or AIA method, but the difference of OMD determined by Cr₂O₃and AIA method was significant (P＜0.05). The fecal recovery of Cr₂O₃was 90.74% and was lower than that of AIA (118.17%). In conclusion, Cr₂O₃ may be used as a marker to measure digestibility in steers.
