This experiment was conducted to study the effects of adding sulfur-anion complex preparation into the late fattening period diet on growth performance, nutrient apparent digestibility and slaughter performance of Yanbian yellow cattle. A total of 60 healthy Yanbian yellow cattle bullocks with an average body weight of (550±16) kg were randomly allocated into 4 groups with 15 bullocks per group. The bullocks in group Ⅰ (control group) were fed a basal diet, and those in groups Ⅱ, Ⅲ and Ⅳ (test groups) were fed the basal diets supplemented with 16, 18 and 20 mg/(bullock·d), respectively. There was a pretrial period of 10 d followed by an experimental period of 90 d. The results showed as follows: compared with the group Ⅰ, the average daily gain and average daily feed intake in the group Ⅳ were significantly increased by 34.69% and 4.33%, respectively (P<0.05). The feed conversation ratio in the group Ⅳ was significantly reduced by 26.37% compared with the group Ⅰ (P<0.05). No significant differences were observed in the apparent digestibility of dry matter, ether extract, ash, calcium and phosphorus among all groups (P>0.05). The apparent digestibility of crude protein and crude fiber in the group Ⅳ was significantly improved by 5.28% and 5.35% compared with the group Ⅰ, respectively (P<0.05). No significant differences were observed in slaughter performance among all groups (P>0.05). In conclusion, adding sulfur-anion complex preparation into the late fattening period diet can improve the growth performance and nutrient apparent digestibility of Yanbian yellow cattle, and 20 mg/(bullock·d) is considered to be the optimal level under conditions of this experiment.
