养殖场自己发酵，现配再用，行否？

既然干燥的发酵豆粕消化率要低，为什么在仔猪上具有抗营养性下痢的优势？是因为发 ...

ShiZhu兄好，除赖氨酸外，发酵豆粕的氨基酸消化与豆粕相当，发酵豆粕赖氨酸的消化率比豆粕要低。最近有文献报道过

感谢楼主的经验之谈，但本人对此有不同意见。
我们是饲料企业，曾经使用过多家的发酵豆粕产品 ...

除赖氨酸外，发酵豆粕的氨基酸消化与豆粕相当，发酵豆粕赖氨酸的消化率比豆粕要低。最近有文献报道过，Stein是这篇文章的通讯作者，该文发表在2010年的Journal of Animal Science上。具体有多大差异，上面已经有一位网友给出来了

发酵产品的质量难以控制，这一批好点，下一批会因为各种条件的变化而结果与前一批不一致之所以到现在还没有大面积推广，就是这个原因，

发酵豆粕要使用出效果必须是加120%的水进去发酵，使用起来必须要直接使用，这样的效果刚刚的 ~比其他一切效果好多啦

Ileal digestibility of amino acids in conventional, fermented, and enzyme-treated soybean meal and in soy protein isolate, fish meal, and casein fed to weanling pigs1

An experiment was conducted to determine the apparent (AID) and standardized (SID) ileal digestibility of CP and AA in weanling pigs of 4 soybean products, fish meal, and casein. The 4 soybean products were conventional dehulled soybean meal (SBM), soy protein isolate (SPI), fermented soybean meal (FSBM), and enzyme-treated soybean meal (ESBM). Seven weanling barrows (initial BW: 10.9 ± 2.3 kg) were individually fitted with a T-cannula in the distal ileum. The barrows were allotted to a 7 x 7 Latin square design with 7 diets and seven 7-d periods. Six cornstarch-based diets were prepared using each of the protein sources as the sole source of CP and AA. An N-free diet was used to measure basal endogenous losses of CP and AA. Results showed that except for Lys, the AID and SID of AA in FSBM was not different from SBM, and with a few exceptions, the AID and SID of most AA in SBM, FSBM, and ESBM were not different from each other and from the AID and SID of AA in fish meal. Likewise, the AID and SID of AA in ESBM and SPI were not different, but the AID and SID of most AA in SPI were greater (P < 0.05) than in SBM and FSBM. The AID and SID of most AA in SPI were not different from the AID and SID of AA in casein. In conclusion, FSBM and ESBM had similar SID of most AA as SBM, but SPI has the greatest SID of AA among the 4 soybean products. Casein had the greatest SID of AA among the protein sources studied.
