| Abstract: | 【Objective】In order to improve the production performance of yaks.【 Method】63 domestic yak were randomly selected as the control,57 yaks containing half blood of wild yak were as the test group.The body size,body weight and daily weight gain were measured at six-month and 18-month old,respectively,then the data was tested by variance analysis.【 Result】The result showed that the body height,body length,chest circumference,circumference of cannon bone,body weight of the yaks conta-i ning half blood of wild yak at six-month old increased 7.48%,7.93%,8.03%,9.64% and 24.26% than that of domestic yak with the same age,the difference was significant（P 0.01）.The daily weight gain of hybrid yaks increased 60.80 g and 54.72 g at six-month and 18-month old compared with the same age domestic yak,and the difference was significant（P 0.01）.【 Conclusion】The production performance and rejuvenation effect of domestic yak improved by wild yak could be obviously increased. |
