摘要
To elucidate the efficacy of different levels of microbial-fermented soy proteins (FSP) on piglet performance, a total of 240 weaned piglets (, d of age, kg initial BW) were allotted to 4 treatment diets comprising control, FSP-3%, FSP-6% and FSP-9%. The fermented soybean product named was utilized for the study. There were 15 pigs per pen and 4 pens per treatment. The control diet contained 15% soybean meal (SBM), and SBM for the treatment diets was replaced at 3, 6 and 9% with FSP, respectively. Experimental diets were fed from 0 to 14 d (phase-I) after weaning and then a common commercial diet was fed from 15 to 35 d (phase-II). There was a linear (p<0.05) increase in ADG and ADFI at both phases of measurement. The feed to gain ratio was also improved, showing a linear (p<0.01) trend as the level of supplementation increased. Except for phosphorus, the digestibility of all other nutrients was improved linearly (p<0.05) in the FSP added diets. However, villous height and crypt depth were not affected by dietary treatments. No special effect on intestinal morphology was noticed between FSP-added and control diets. In conclusion, the growth, digestibility of nutrients and morphological changes in weaned pigs fed FSP showed improved performance at higher levels of supplementation.

为了阐明不同水平的微生物发酵大豆蛋白（FSP）对仔猪生产性能的影响，共240只断奶仔猪（d，年龄，将kg初始BW分配至4种处理饮食，包括对照，FSP-3％，FSP-6％和FSP-9％。名称的发酵大豆产品用于该研究。每支猪有15头猪，每次处理有4头。对照饮食含有15％豆粕（SBM），处理日粮的SBM分别用FSP替换为3％，6％和9％。实验饮食在断奶后从0到14天（阶段I）喂养，然后从15到35天喂食普通商业饮食（阶段II）。有一个线性（p 0。05）在测量的两个阶段增加ADG和ADFI。饲料增重比也得到改善，随着补充水平的增加呈现线性（p 0.01）趋势。除了磷，在添加FSP的日粮中，所有其他营养素的消化率均线性提高（p 0.05）。然而，绒毛高度和隐窝深度不受饮食处理的影响。在FSP添加和对照饮食之间没有注意到对肠道形态的特殊影响。总之，增长，饲喂FSP的断奶仔猪的养分消化率和形态变化表明，在较高的补充水平下，其表现有所改善。
