This study aimed to examine B4's fermentation efficiency and the growth performance of newly weaned pigs fed B4 fermented soybean meal (B4-FSBM).
Soybean meal (SBM) was inoculated with B4 and fermented at room temperature for 48 hours. Following fermentation, analysis was performed to examine anti-nutritional factor degradation efficiency. Fermentation broke down large molecular weight proteins, consistent with sizes of glycinin and β-conglycinin into smaller proteins. Crude protein significantly increased from 51.5% to 56.5%. Neutral detergent fiber (NDF) was reduced by 26.9% (P < 0.05), while the phytate phosphorus content was reduced by 59.16% (P < 0.05) in B4-FSBM. In the animal trial, 90 newly weaned piglets were divided into three groups, receiving either the negative control (NC; 25.4% SBM), positive control (PC; 25.4% SBM supplemented with 3000 mg/kg zinc oxide), or B4 (B4; 19% FSBM, 6.4% SBM). There was a temporary setback in growth performance for pigs fed B4-FSBM during the early weeks. However, their growth performance improved, and by the fourth week, their gain-to-feed ratio was significantly improved when compared to the control groups. Additionally, pigs fed B4-FSBM had increased (P < 0.05) crude protein digestibility compared to the NC for weeks 3 and 4.
Fermentation of SBM with B4 improves feed efficiency and protein digestibility in weaned pigs.
本研究旨在考察B4的发酵效率以及饲喂B4发酵豆粕(B4-FSBM)的断奶仔猪的生长性能。
用B4接种豆粕(SBM),并在室温下发酵48小时。发酵后,进行分析以检测抗营养因子的降解效率。发酵将大豆球蛋白和β-伴大豆球蛋白大小的大分子蛋白质分解为较小的蛋白质。粗蛋白含量从51.5%显著增加到56.5%。B4-FSBM中的中性洗涤纤维(NDF)减少了26.9%(P<0.05),植酸磷含量减少了59.16%(P<0.05)。在动物试验中,90头断奶仔猪被分为三组,分别接受阴性对照(NC;25.4%SBM)、阳性对照(PC;25.4%SBM添加3000mg/kg氧化锌)或B4(B4;19%FSBM,6.4%SBM)。在最初几周,饲喂B4-FSBM的猪的生长性能出现了暂时的下降。然而,它们的生长性能有所改善,到第四周时,与对照组相比,它们的料重比显著提高。此外,在第3周和第4周,饲喂B4-FSBM的猪的粗蛋白消化率比NC组有所提高(P<0.05)。
用B4发酵SBM可提高断奶仔猪的饲料效率和蛋白质消化率。
