【摘要】：試驗(yàn)研究不同水平的發(fā)酵木薯酒精糟對(duì)生長(zhǎng)豬生產(chǎn)性能的影響。選擇200頭初始體重約(26.35±0.43)kg的生長(zhǎng)豬,隨機(jī)分為5個(gè)處理組,每組4個(gè)重復(fù),每個(gè)重復(fù)10頭豬。5個(gè)處理組分別為:A組為對(duì)照組,飼喂基礎(chǔ)日糧;B組、C組和D組分別為發(fā)酵木薯酒精糟用量為2%、6%和15%的配合日糧組,E組則為用發(fā)酵木薯酒精糟直接替代6%基礎(chǔ)日糧的混合日糧組。結(jié)果表明,B組和C組的日增重較A組分別提高了6.45%(P0.05)和4.84%(P0.05),各試驗(yàn)組料肉比均低于對(duì)照組,分別降低了7.48%、9.06%、5.12%和0.39%。日糧中添加發(fā)酵木薯酒精糟后有效改善了營(yíng)養(yǎng)物質(zhì)消化率,B組、C組、D組及E組干物質(zhì)消化率較對(duì)照組分別提高了8.62%(P0.05)、7.50%(P0.05)、4.75%(P0.05)和5.26%(P0.05);粗蛋白消化率較對(duì)照組分別提高了11.43%(P0.05)、9.50%(P0.05)、9.61%(P0.05)和10.61%(P0.05);粗脂肪消化率較對(duì)照組分別提高了15.66%(P0.05)、15.86%(P0.05)、12.98%(P0.05)和14.10%(P0.05);鈣的消化率則較對(duì)照組分別提高了10.46%(P0.05)、6.50%(P0.05)、6.93%(P0.05)和10.60%(P0.05)。B組、C組、D組及E組較A組的養(yǎng)殖效益均有所提高,每千克飼料的增重成本分別降低了0.683、0.833、0.523元和0.238元,其中使用處理C組飼料的效益最好。本試驗(yàn)結(jié)果說(shuō)明,生長(zhǎng)豬日糧中發(fā)酵木薯酒精糟的適宜添加量為2%~6%,能有效提高豬的生產(chǎn)性能和養(yǎng)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 鹵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.
