S823; In this study, the effects of two types of premixed materials with different combinations of trace elements on the production performance and antioxidant capacity of simmental beef cattle were examined. Fifteen healthy simmental beef cattle of similar weight (approximately 330 kg), the same age (12 months), without castration, and a good physique were divided into three groups, with five beef cattle in each group. Food of GroupⅠbeef cattle was supplemented with a commercially marketed 5％ compound trace element premixture for fine beef cattle. Food of GroupⅡbeef cattle was supplemented with a 5％ compound microelement premixture for beef cattle that was designed to address local nutrient deficiencies and surpluses. In the blank control group, the beef cattle were not fed a premixture. The pretest period was 15 days, and the test period was divided into prefattening (45 days) and postfattening (45 days) stages. Body weight and body size indices were recorded at 1, 2 and 3 months, and blood samples were collected regularly. In GroupⅠ, the daily weight gain increased significantly by 15.7％ compared with that of the control group. The largest daily weight gain was in Group Ⅱ, which increased by 31.6％ compared with that in the control. During the test period of 90 days, the body size indices of the three different groups increased in different months, with significant increases in the indices for both test groups compared with those of the control. In GroupⅠ, the activity of CP, the total activity of SOD and Cu-Zn-SOD increased significantly (p<0.05) compared with those in the control group, with a highly significant increase observed in GSH-PX activity (p<0.01). In GroupⅡ, the increases in the activity of CP and the total activity of SOD and Cu-Zn-SOD were highly significant compared with those in the control group (p<0.01). In addition, a significant increase was observed in GSH-PX activity (p<0.05). Based on pretest results, the concentrations of Cu, Zn, Mo, Mn, Se and Co in the blood of experimental beef cattle were lower than those of the normal range. After feeding for 90 days, the concentrations of Cu, Zn, Mo, Mn, Se and Co in the blood of GroupsⅠandⅡwere significantly higher than those in the control group (p<0.05). The concentrations of elements in the blood of Group II were close to the appropriate levels. Thus, the effects of the specifically designed compound microelement premixture on the prevention of nutrient imbalances and control of beef cattle nutrition metabolism and the production of fattened beef cattle were significant.
