【摘要】：本試驗旨在研究豆粕酶解發(fā)酵物對仔豬生長性能、血清指標及腸道菌群結構的影響。選用144頭49日齡健康的"杜×長×大"三元雜交育肥仔豬,隨機分為3組,每組6個重復,每個重復8頭豬(公母各占1/2)。陰性對照組飼喂無抗生素添加的基礎飼糧,抗生素對照組飼喂基礎飼糧+60 g/t吉他霉素,試驗組飼喂試驗飼糧(基礎飼糧中10%豆粕被豆粕酶解發(fā)酵物替代)。試驗期為42 d。結果表明:1)試驗組仔豬的末重、平均日增重、平均日采食量分別比陰性對照組高5.06%、10.07%、5.03%(P0.05),腹瀉率比陰性對照組低39.59%(P0.05),與抗生素對照組相比各指標差異均不顯著(P0.05)。2)試驗組仔豬血清堿性磷酸酶和谷丙轉氨酶活性、總抗氧化能力(T-AOC)、超氧化物歧化酶(SOD)活性均顯著高于陰性對照組(P0.05),丙二醛(MDA)含量顯著低于陰性對照組(P0.05);試驗組和抗生素對照組仔豬血清指標差異不顯著(P0.05)。3)試驗組仔豬盲腸、大腸中乳酸桿菌數(shù)量顯著高于陰性對照組和抗生素對照組(P0.05),十二指腸中總細菌數(shù)顯著低于陰性對照組和抗生素對照組(P0.05)。綜上,豆粕酶解發(fā)酵物能提高仔豬生長性能,增強機體抗氧化能力,利于乳酸桿菌在腸道內(nèi)形成優(yōu)勢菌群,降低腹瀉率,生長性能達到使用抗生素水平。
[Abstract]:The purpose of this experiment was to study the effect of soybean meal enzymatic fermentation on growth performance, serum index and intestinal microflora structure of piglets. 144 49-day-old "du 脳 Chang 脳 Da" crossbred piglets were randomly divided into 3 groups, 6 replicates in each group, 8 pigs per replica (male / female, 1 / 2). The negative control group was fed with basic diet without antibiotic addition, the antibiotic control group was fed with 60 g / t guitar, and the experimental group was fed with the experimental diet (10% soybean meal was replaced by soybean meal enzymatic fermentation). The experimental period is 42 days. The results showed that: 1) the litter weight, average daily gain and average daily intake of piglets in the test group were 5.06% and 5.03% (P0.05) higher than those in the negative control group, respectively, and the diarrhea rate was 39.59% (P0.05) lower than that in the negative control group. Compared with the antibiotic control group, there was no significant difference between the two groups (P0.05). 2) the serum alkaline phosphatase and alanine aminotransferase activities, total antioxidant capacity (T-AOC) of the piglets in the experimental group were not significantly different from those in the antibiotic control group. The activity of superoxide dismutase (SOD) was significantly higher than that of negative control group (P0.05), and the content of malondialdehyde (MDA) was significantly lower than that of negative control group (P0.05). There was no significant difference in serum indexes between the experimental group and the antibiotic control group (P0.05). 3. The number of Lactobacillus in the large intestine of the experimental group was significantly higher than that of the negative control group and the antibiotic control group (P0.05). The total bacterial count in duodenum was significantly lower than that in negative control group and antibiotic control group (P0.05). In conclusion, the enzymatic hydrolysis of soybean meal fermentation could improve the growth performance of piglets, enhance the antioxidant capacity of the body, and help Lactobacillus to form dominant bacteria in the intestinal tract, reduce the diarrhea rate, and reach the level of antibiotics.
