| Abstract: | yak herds respectively containing 103(experiment group)and 62(controlgroup)yaks grazed in green grass land were used in a 88-day test,0.25kg concentrate wassupplemented to each animal each day for the experiment group and nothing for the controlgroup.As compared with control group,weight gain rates of yaks aged2,3,4 years in experi-ment group increased by 20.1,14.5 and 4.9 percent unit resp.body weight of 2 and 3 year-oldyak increased by 50.8%and 9.7%(P<0.01),while no body weight increase for 4-year old yakwas found.The result suggest that the summer grassland can not supply sufficient hutrients re-quired by growing yaks,and the adaptability of yak to the summer grassland increases with the age. |
