用微生物降解法从脱脂豆粕、玉米胚粕中制取混合氨基酸液。内有18种氨基酸,其中人体必需的8种氨基酸占混合氨基酸总量的41.5％,氨基酸生成率40％,产率18％,原料蛋白质利用率87.2％,氨基氮生成率52.6％。 将实验动物喂基础饲料,以混合氨基酸液代替饮用水,分为A(100％代替),B(50％代替),C(33％代替)和D(100％自来永对照)四个组,观察对生长试验,游泳试验和抗缺氧死亡时间的影响。经方差分析,结果表明,脱脂豆粕、玉米胚粕制取的混合氨基酸液对促进动物生长(A、B、C∶D与B∶C分别为p<0.001和p<0.01,A∶C p<0.05)、提高抗疲劳(A、B∶D和A∶C分别p<0.001,p<0.01)、抗缺氧能力(A∶B、C、D,B∶D,C∶D均为p<0.001)和增强耐力都有一定作用。
Microbial degradation method from defatted soybean meal, corn germ meal in the preparation of mixed amino acid solution. There are 18 kinds of amino acids, of which 8 kinds of essential amino acids accounted for 41.5% of the total amino acid mixture, the amino acid formation rate of 40%, the yield of 18%, raw material utilization rate of 87.2%, amino nitrogen formation rate of 52.6%. The experimental animals were fed the basal diet and mixed with amino acid solution instead of drinking water. The experimental animals were divided into four groups of A (100% substitution), B (50% substitution), C (33% substitution) and D (100% , Observe the growth test, swimming test and anti-hypoxia death time. The results of variance analysis showed that the mixed amino acid solution prepared from defatted soybean meal and corn embryo meal could promote the growth of animals (p <0.001 and p <0.01, A: Cp < 0.05), anti-fatigue (A, B: D and A: C respectively p <0.001, p <0.01) 0.001) and enhance endurance have a certain effect.
