本试验研究了豆粕、大豆浓缩蛋白和发酵豆粕的代谢能、氨基酸标准回肠消化率及其在早期断奶仔猪中的应用。在Exp.试验采用4×4拉丁方设计，选用4头初体重为14.2± 1.4kg的公公猪。饮食1含有玉米作为唯一的能量来源。其余三种饲粮用3种豆制品中的一种替代饲粮1中25%的玉米，用差值法测定饲粮1的消化能和代谢能含量。在Exp. 2，4头公猪（初始体重为18.2±1.5 kg）安装回肠T形插管，并分配到4×4拉丁方设计。三个玉米淀粉为基础的饮食，制定使用每一种大豆产品作为唯一来源的AA。还配制了无氮饮食以测量AA的内源性损失。在Exp. 3、96头21±2日龄断奶仔猪（初始体重5.6±0.9 kg）按体重分组，随机分为3组，进行21日龄生长性能试验。对照日粮以玉米和豆粕为基础，两个处理的日粮含有10%的SPC或FSBM，并配制成相同的SID赖氨酸与ME的比例为3.6 g/Mcal。结果表明，SPC的ME含量显著高于SBM（p<0.05）。SPC中大多数AA的SID大于SBM中AA的SID（p<0.05）。必需氨基酸中组氨酸、异亮氨酸、亮氨酸、赖氨酸和苏氨酸的SID，FSBM大于SBM（p<0.05）。即使饲喂相同的SID赖氨酸/ME比3.6 g/Mcal日粮，饲喂SPC和FSBM日粮的猪比饲喂SBM日粮的猪具有更大的增重、G：F（p<0.05）和更好的粪便评分（p<0.05）。总之，SPC比SBM显示出更高的ME含量和AA的SID。FSBM中某些必需氨基酸的SID高于SBM，与SPC相似。但SPC和FSBM中抗原蛋白和抗营养因子含量较低可能是影响早期断奶仔猪生产性能的主要因素，而不是AA中ME含量和SID的增加。
Three experiments were conducted to evaluate the metabolizable energy (ME) value, standardized ileal digestibility (SID) of amino acids (AA) of soybean meal (SBM), soy protein concentrate (SPC) and fermented soybean meal (FSBM), and the application of these products in early-weaned piglets. In Exp. 1, four barrows with initial body weight (BW) of 14.2±1.4 kg were used in a 4×4 Latin square design. The diet 1 contained corn as the only energy source. The other three diets replaced 25% of corn in diet 1 with one of the three soybean products, and the digestable energy (DE) and ME contents were determined by difference. In Exp. 2, four barrows (initial BW of 18.2±1.5 kg) were fitted with ileal T-cannulas and allotted to a 4×4 Latin square design. Three cornstarch-based diets were formulated using each of the soybean products as the sole source of AA. A nitrogen-free diet was also formulated to measure endogenous losses of AA. In Exp. 3, ninety six piglets (initial BW of 5.6±0.9 kg) weaned at 21±2 d were blocked by weight and assigned to one of three treatments for a 21-d growth performance study. The control diet was based on corn and SBM, the two treatments’ diets contained either 10% SPC or FSBM and were formulated to same SID lysine to ME ratio of 3.6 g/Mcal. The results showed that the ME content of SPC was greater than SBM (p<0.05). The SID of most AA in SPC was greater than the SID of AA in SBM (p<0.05). For the essential AA, the SID of histidine, isoleucine, leucine, lysine and threonine in FSBM were greater than in SBM (p<0.05). Even though they were fed same SID lysine to ME ratio of 3.6 g/Mcal diets, pigs fed SPC and FSBM diets had greater weight gain, G:F (p<0.05) and better fecal score (p<0.05) than pigs fed SBM diet. In conclusion, SPC showed a higher ME content and SID of AA than the SBM. SID of some essential AA in FSBM was higher than SBM and was similar with SPC. But the lower antigenic proteins and anti-nutritional factors content in SPC and FSBM may be the main factors affecting the performance of early-weaned piglets rather than the increased ME content and SID of AA.
