摘要
5头带瘤胃和真胃瘘管的绵羊饲喂7种不同的日粮,日粮中加入食糜标记物——三氧化二铬(Cr_2O_3)和聚乙二醇(PEG)以测定真胃食糜干物质日流量。使用单标记物Cr_2O_3、PEG和双标记物(Cr_2O_3和PEG)的技术测定日干物质流量时,结果没有显著的差异,但单标记物PEG的测定结果变异较大。
Five sheep, fitted with a rumen cannula and abomasum cannula were given seven diets consisting of basal dietary and different protein supplement. The diets were designed by a 5×7 uncompleted Latin-square. Chromic oxide (Cr2O8) and polyethylene glycol (PEG) were given as digesta markers. The results showed that the outflow of dry matter of abomasum digesta measured with the simple marker Gr2O3 or PEG and double marker methods had no significant difference
