An experiment to calculate the fecal recoveries of alkanes was carried out at the Inner Mongolia Grassland Ecosystem Research Station of the Chinese Academy of Sciences in autumn 2004. Twelve wethers (Inner Mongolia fine wool sheep×Inner Mongolia sheep) selected from a group of two year olds were fed fresh mixtures of Leymus chinensis (30%), Cleistogenes squarrosa (20%) and Artemisia frigida (50%) in known proportions and amounts for 14 days.

2004年秋季在中国科学院内蒙古草原生态系统定位站，用不同放牧演替阶段的优势植物羊草、糙隐子草和冷蒿分别按30%、20%和50%的比例混合组成日粮，饲喂12只(39±2.1kg)2岁羯羊。

Nine wethers selected from a group at 2-years-old of age were fed with fresh mixtures of Leymus chinensis (30%), Cleistogenes squarrosa (20%) and Artemisia frigida (50%) in known proportions and amounts for 14 days. Artificial QSM capsules were dosed during the experiment. The samples of herbage and feces were collected daily for 7 days and dried for analysing the n-alkane concentration by a gas chromatography. The results showed that there was a difference in concentration of n-alkanes among 3 species forages, and fecal recoveries of n-alkanes linear increased with increasing carbon chain lengths.

于2004年秋季在中国科学院内蒙古草原生态系统定位研究站用不同放牧演替阶段的优势植物羊草、糙隐子草和冷蒿按一定比例混合组成日粮，饲喂9只2岁羯羊，每只羊投喂一粒QSM胶囊，试验期内每天记录绵羊实际牧草采食量、采食成分和排粪量，利用气相色谱分析牧草和粪样的链烷含量，应用链烷技术测定绵羊的排粪量、不同牧草采食比例和总干物质采食量，并与实际值进行比较。
