Data

Our dataset includes 1346 Simmental cattle born between 2008 and 2015 from Ulgai, Xilingol League, and Inner Mongolia, China. After weaning, cattle were moved to Jinweifuren Co., Ltd. (Beijing, China) for fattening under the same feeding and management conditions. A more detailed description of the management processes was reported in previous studies (Zhu et al., 2016, 2017). All individuals were slaughtered at an average age of 20 months, and carcass and meat quality traits were measured in accordance with the guidelines proposed by the Institutional of Meat Purchase Specifications. All animals used in the study were treated following the guidelines established by the Council of China Animal Welfare. Protocols of the experiments were approved by the Science Research Department of the Institute of Animal Sciences, Chinese Academy of Agricultural Sciences (CAAS) (Beijing, China). The approval ID/permit numbers are SYXK (Beijing) 2008-007 and SYXK (Beijing) 2008-008. In our study, carcass weight (CW), live weight (LW), and striploin (SI) were analyzed, and their statistical description was summarized in Table 1.
