| 中文摘要 | our goal was to determine the effect of diets with different crude protein (cp) contents and metabolizable energy (w) levels on daily live-weight gain, apparent digestibility, and economic benefit of feedlot yaks on the tibetan plateau during winter. yaks were either 2- or 3-years old and randomly selected from the same herd. the 3-year-olds were placed into one of two experimental groups (a and b) and a control (ck1), and the two-year-olds were placed into one of three experimental groups (c, d and e) and a control (ck2) (n per group = 5). yak in the control groups were allow graze freely, while those in the experimental groups yaks were fed diets higher in contains crude protein and metabolizable energy through a winter period inside a warming shed. results indicated that live-weight gain of treatment groups was higher than their respective controls during experiment, and that daily live-weight gain of every 10 days among different treatments was significant difference (p < 0.05). in addition, apparent digestibility of different diets was linearly and positively related to feedlotting time, and feed conversion efficiency for a, c, d and e groups was quadratically related to feedlotting time (p < 0.01), however, feed conversion efficiency for b group was linearly and positively related to feedlotting time (p < 0.05). the economic benefit was 1.15 for a, 1.89 for b, 1.16 for c, 1.54 for d, and 4,52 for e.
