| Abstract: | The beef performance of some Chinese yellow cattle breeds: Qinchuan 25 hd,Jinnan 25 hd,Yanbian 10 hd,Fuzhou 10 hd, Bohai Black 11 hd and Koresin 30 hd,was studied. With barn feeding and 8 - 10hd each pen, average initial weight about 200kg, slaughter weight averaged about 540kg. In the all period of finishing, formulation of feeds and water were supplied ad libitum. The results of this study showed that dressing percentage 61. 3- 64. 2 %, lean meat percentage 51.1 - 54. 5 %,carcass weight 318. 7 - 363. 2kg bone percentage of carcass 7. 55 - 8. 72%, meat tobone rato 5. 8- 6. 74 of these breeds were tested. These results suggested the lower dressing percentage of Chinese yellow cattle, formerly . they conidered, might be from the lower slaughter bodyweight and without a proper long finish period for the breeds. |
