  本试验研究了断奶至出栏期间用低寡糖豆粕替代普通豆粕对猪生长性能和胴体品质的影响。试验共计432头杂交断奶仔猪(19日龄,初始重6.6±1.2kg),根据体重和性别分为6个处理组:1)所有阶段为普通豆粕,阶段1-3使用鱼粉和血浆蛋白粉;2)所有阶段为普通豆粕,但不使用鱼粉和血浆蛋白粉;3)阶段1-3使用低寡糖豆粕、血浆蛋白粉和鱼粉,其它阶段使用普通豆粕;4)阶段1-3使用低寡糖豆粕,其它阶段使用普通豆粕;5)阶段1-6使用低寡糖豆粕,阶段1-3使用鱼粉和血浆蛋白粉;6)阶段1-6使用低寡糖豆粕。试验结果表明总体生长性能(日增重、采食量和料肉比)和胴体性能(胴体重、屠宰率、背脂厚度、眼肌面积、瘦肉率)不受日粮处理的影响(P>0.05)。

  此外,在阶段1-3日粮中无鱼粉和血浆蛋白粉时,使用低寡糖豆粕替代普通豆粕不影响早期生长性能,但是在早期日粮中含鱼粉和血浆蛋白粉的情况下,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)。在阶段2中,低寡糖豆粕组血浆尿素氮含量显著升高。总之,在断奶-育肥阶段通过使用低寡糖豆粕替代普通豆粕降低寡糖含量并不能改善猪的生长性能和胴体品质。

  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.
