Abstract

Abstract: In order to research the slaughter performance and meat quality of yak cows in Cha Wula district, ten 8-year-old yaks (5 males and 5 females) were randomly selected to determine slaughter performance and muscle quality. It was found that the female yaks had a higher dressing out percentage, net meat yield, and bone-meat yield than males. However, the eye muscle in male yak was of greater diameter than in the females. The analysis of nutrient composition of yaks showed that the contents of vitamin A, E, B₁₂, cysteine, histidine, arginine, calcium, selenium and fatty acids in male yaks were higher than those in female yaks (P<0.05). The results showed that Cha Wula yak meat is rich in highly nutritional components, and therefore is able to provide high quality animal protein for human consumption. In conclusion, compared with male yak meat, female yak meat is superior.

Key words: yak, meat production, nutritional composition
