　　本試驗研究了斷奶至出欄期間用低寡糖豆粕替代普通豆粕對豬生長性能和胴體品質的影響。試驗共計432頭雜交斷奶仔豬（19日齡，初始重6.6±1.2kg），根據體重和性別分為6個處理組：1）所有階段為普通豆粕，階段1-3使用魚粉和血漿蛋白粉；2）所有階段為普通豆粕，但不使用魚粉和血漿蛋白粉；3）階段1-3使用低寡糖豆粕、血漿蛋白粉和魚粉，其它階段使用普通豆粕；4）階段1-3使用低寡糖豆粕，其它階段使用普通豆粕；5）階段1-6使用低寡糖豆粕，階段1-3使用魚粉和血漿蛋白粉；6）階段1-6使用低寡糖豆粕。試驗結果表明總體生長性能（日增重、采食量和料肉比）和胴體性能（胴體重、屠宰率、背脂厚度、眼肌面積、瘦肉率）不受日糧處理的影響（P＞0.05）。

　　此外，在階段1-3日糧中無魚粉和血漿蛋白粉時，使用低寡糖豆粕替代普通豆粕不影響早期生長性能，但是在早期日糧中含魚粉和血漿蛋白粉的情況下，使用低寡糖豆粕替代普通豆粕降低采食量（P≤0.05）、提高肉料比（P＜0.05）。在階段2中，低寡糖豆粕組血漿尿素氮含量顯著升高?？傊跀嗄?育肥階段通過使用低寡糖豆粕替代普通豆粕降低寡糖含量并不能改善豬的生長性能和胴體品質。

　　A trial was conducted to determine the effect of replacing conventional soybean meal (CSBM) with low-oligosaccharide soybean meal (LOSBM) on growth performance and carcass characteristics of wean-to-finish pigs. A total of 432 crossbred pigs (19 d and 6.6 ± 1.2 kg BW) were blocked by sex and BW and assigned to 1 of 6 dietary treatments: 1) CSBM in all phases and fishmeal and spray-dried plasma protein (FM/SDPP) in phases 1 to 3, 2) CSBM in all phases but with no FM/SDPP, 3) LOSBM and FM/SDPP in phases 1 to 3 and CSBM in phases 4 to 6, 4) LOSBM in phases 1 to 3 and CSBM in phases 4 to 6, 5) LOSBM in phases 1 to 6 and FM/SDPP in phases 1 to 3, and 6) LOSBM in phases 1 to 6. The results showed that pig growth performance (ADG, ADFI, and G:F) during the overall period (phases 1 to 6) and carcass traits (HCW, dressing percentage, fat depth, loin depth, and lean percentage) were not affected (P > 0.05) by dietary treatments. Moreover, replacing CSBM with LOSBM in phases 1 to 3 did not affect early phase growth performance in the absence of FM/SDPP but reduced (P ≤ 0.05) ADFI and increased (P < 0.05) G:F during the nursery period (phases 1 and 2) in the presence of FM/SDPP. In phase 2, LOSBM increased (P < 0.05) blood urea nitrogen in comparison with CSBM. In conclusion, reduction of oligosaccharide by replacing CSBM with LOSBM in the early, late, or entire phase of the wean-to-finish period did not improve growth performance and carcass characteristics of pigs.
