| Abstract: | Objective] The purpose of the experiment is to investigate the fattening effect, slaughtering character and meat quality of the introduced Charolais in Qinghai province, and to evaluate the feasibility of the popularization and crossbreeding of Charolais in Qinghai province. Method] The fattening contrast experiment of Charolais at the age of 6 months and Simmental at the same age was carried out in Qinghai Jinxiu Agricultural Development Co. Ltd.. At the end of the feeding trial, to analyze the differences of slaughtering performance, carcass and meat quality, the slaughtering performance of 15-month-old Charolais and local Simmental cattle were measured. Result] The results showed that the slaughter rate of Charolais cattle after fattening could reach 57.80%, the net meat rate was 46.40%, the carcass meat production rate was 80.30%, and the meat/bone ratio was 4.23. All indexes were better than the local Simmental cattle. The essential amino acid content and essential fatty acid content of Charolais beef were 7.96% and 3.29%, respectively, which were not significantly different from native Simmental beef. Conclusion] Overall, Charolais have good growth performance and slaughter performance than Simmental, while their beef meat quality and nutrition levels are close. Therefore, Charolais are suitable for local fattening and promotion. |
