【摘要】：试验研究不同水平的发酵木薯酒精糟对生长猪生产性能的影响。选择200头初始体重约(26.35±0.43)kg的生长猪,随机分为5个处理组,每组4个重复,每个重复10头猪。5个处理组分别为:A组为对照组,饲喂基础日粮;B组、C组和D组分别为发酵木薯酒精糟用量为2%、6%和15%的配合日粮组,E组则为用发酵木薯酒精糟直接替代6%基础日粮的混合日粮组。结果表明,B组和C组的日增重较A组分别提高了6.45%(P0.05)和4.84%(P0.05),各试验组料肉比均低于对照组,分别降低了7.48%、9.06%、5.12%和0.39%。日粮中添加发酵木薯酒精糟后有效改善了营养物质消化率,B组、C组、D组及E组干物质消化率较对照组分别提高了8.62%(P0.05)、7.50%(P0.05)、4.75%(P0.05)和5.26%(P0.05);粗蛋白消化率较对照组分别提高了11.43%(P0.05)、9.50%(P0.05)、9.61%(P0.05)和10.61%(P0.05);粗脂肪消化率较对照组分别提高了15.66%(P0.05)、15.86%(P0.05)、12.98%(P0.05)和14.10%(P0.05);钙的消化率则较对照组分别提高了10.46%(P0.05)、6.50%(P0.05)、6.93%(P0.05)和10.60%(P0.05)。B组、C组、D组及E组较A组的养殖效益均有所提高,每千克饲料的增重成本分别降低了0.683、0.833、0.523元和0.238元,其中使用处理C组饲料的效益最好。本试验结果说明,生长猪日粮中发酵木薯酒精糟的适宜添加量为2%~6%,能有效提高猪的生产性能和养殖效益。
[Abstract]:The effects of different levels of fermented cassava alcohol grains on the performance of growing pigs were studied. 200 pigs with initial body weight of about 26.35 卤0.43 kg were randomly divided into 5 treatment groups with 4 replicates in each group. 10 pigs per replica. Five treatment groups were divided into two groups: group A, control group, The mixed diet groups C and D were mixed diets with fermented cassava alcohol grains of 2% and 15% respectively, which were mixed diets with fermented cassava alcohol grains instead of 6% basal diets. The results showed that fermentative cassava alcohol grains were used in the mixed diets of 2% and 15% respectively. The results showed that the two groups were mixed diets with fermentative cassava alcohol grains instead of 6% basal diets. Compared with group A, the daily gain of group C was increased by 6.45% (P 0.05) and 4.84% (P 0.05), and the feed / meat ratio of group C was lower than that of control group. The digestibility of dry matter in group C and group E was increased by 8.62P0.05P0.05P0.05P0.05 and 5.265P0.05, respectively, and the digestibility of crude protein was higher than that of the control group, and the digestibility of crude protein in group B was higher than that in group B, and the digestibility of dry matter in group C and group E was higher than that in group B, and the digestibility of crude protein in group B was higher than that in group C and group E, respectively, compared with that in group B, and the digestibility of crude protein in group B was higher than that in group B. The digestibility of crude fat was increased by 15.6666, P 0.05, P 0.05, respectively, and the digestibility of calcium was increased by 15.6666, P 0.05, P 0.05, and 14.10, P 0.05, respectively. The digestibility of calcium was increased by 10.4646, P 0.05, 6.93n, 6.93n, 6.93n, and 10.605, respectively, compared with that of the control group, and the efficiency of cultivation in group C and group E were increased, respectively, compared with those in group A, and the digestibility of calcium in group C and group E was higher than that in group A, and the digestibility of calcium in group C was higher than that in group A, and the digestibility of calcium in group C was higher than that in group A, and the digestibility of calcium in group B was higher than that in group A, and the digestibility of calcium in group C was higher than that in group A, and the digestibility of calcium in group C was higher than that in group A. The cost of weight gain per kilogram of feed was reduced by 0.683n 0.833% 0.523 yuan and 0.238 yuan respectively, among which the benefit of treating group C feed was the best. The optimum addition amount of fermented cassava alcohol grains in the diet of growing pigs was 2% and 6%, which could effectively improve the production performance and breeding efficiency of pigs.
