Abstract:In this experiment, 20 Simmental bulls aged about 10 months and with similar body weight were selected and randomly divided into two groups, 10 bulls in each group. In the case of the same supplementary level of concentrate, feeding whole plant corn silage and yellow silage corn silage were used for comparative analysis. This provides theoretical data for feeding beef cattle with whole plant corn silage, and it will be widely promoted in beef cattle scale farms in the same area or similar areas in the future.
