This experiment was conducted to study the effects of Bacillus subtilis supplementation in different zinc supplemental level diets on growth performance, slaughter performance, meat quality and nutrient utilization of meat geese, and to determine the optimum supplemental level of zinc in the condition of adding Bacillus subtilis. A total of 360 five-week-old Wulong geese with similar body condition were randomly divided into 6 groups with 6 replicates in each group and 10 geese in each replicate. Geese in the control group were fed a basal diet supplemented with 80 mg/kg zinc, without Bacillus subtilis; and others in experimental groups (groups Ⅰ to Ⅴ) were fed the basal diets supplemented with 0, 20, 40, 60 and 80 zinc, respectively, and all supplemented with 250 mg/kg Bacillus subtilis. The experiment lasted for 11 weeks. The results showed as follows:1) the body weight and average daily gain of meat geese in group Ⅲ were significantly higher than those in groups Ⅰ and Ⅴ (P<0.05), the ratio of feed to gain of meat geese in group Ⅳ was significantly lower than that in groups Ⅰ and Ⅴ (P<0.05). The average daily gain was the highest when dietary zinc supplemental level was 47.5 mg/kg, the ratio of feed to gain was the lowest when dietary zinc supplemental level was 15.0 mg/kg. 2) The dressed percentage of meat geese in groups Ⅲ, Ⅳ and Ⅴ was significantly higher than that in groups Ⅰ and Ⅱ (P<0.05). 3) The meat water loss rate of meat geese in groups Ⅱ and Ⅲ was significantly lower than that in groups Ⅳ and Ⅴ (P<0.05). 4) The crude protein utilization of meat geese in groups Ⅱ, Ⅲ and Ⅳ was significantly higher than that in group Ⅰ (P<0.05); the ether extract utilization of meat geese in group Ⅳ was significantly higher than that in group Ⅱ (P<0.01), and significantly higher than that in group Ⅴ (P<0.05); the crude fiber utilization of meat geese in groups Ⅱ, Ⅲ and Ⅳ was significantly higher than that in groups Ⅰ and Ⅴ (P<0.05); the zinc utilization of meat geese in groups Ⅰ, Ⅱ and Ⅲ was significantly lower than that in groups Ⅳ and Ⅴ (P<0.05). 5) The nitrogen excretion of meat geese in groups Ⅱ and Ⅲ was significantly lower than that in group Ⅰ (P<0.05), the nitrogen utilization of meat geese in groups Ⅳ and Ⅴ was significantly higher than that in groups Ⅰ, Ⅱ and Ⅲ (P<0.05). 6) Analysis by paired t test, compared with the control group, the body weight, dressed percentage, percentage of breast muscle, percentage of abdominal fat, meat redness value and utilizations of crude protein, neutral detergent fiber and nitrogen of meat geese in group Ⅴ were significantly increased (P<0.05). In conclusion, the addition of Bacillus subtilis and zinc in the diet can improve the growth performance, slaughter performance and utilizations of crude protein, ether extract, crude fiber and zinc, and reduce the emissions of zinc and nitrogen. Under the condition of dietary Bacillus subtilis supplemental level was at 250 mg/kg, the suitable supplemental level of zinc is 15.0 to 47.5 mg/kg.
