关于猪的最佳碳水化合物组合的信息很少。本研究探讨了淀粉、非淀粉多糖和甘露寡糖的不同组合对断奶猪生长性能、营养物质消化率和微生物群落的影响，为评估猪日粮碳水化合物质量提供了一种新方法。本实验旨在剖析不同碳水化合物组合对断奶猪生长性能、营养物质消化率和微生物群落的影响。通过构建L9(34)正交设计对组合进行优化。研究了三个因素，包括淀粉（直链淀粉与支链淀粉（AM/AP）比例为2:1、1:1、1:2）、非淀粉多糖（NSP）（1%、2%、3%，菊粉与纤维素1:1的混合物）和甘露寡糖（MOS）（400、800、1200 mg/kg），并在这些因素的不同水平下实施了九种组合。 162 头断奶仔猪被随机分配至 9 个日粮处理组，每个处理组有 6 个重复，每个重复有 3 头猪。结果表明，淀粉、NSP 和 MOS 的不同组合会影响饲料增益 (G:F) (p < 0.05)、腹泻发生率 (p < 0.10)、养分消化率 (p < 0.05)、微生物群落和短链脂肪酸 (SCFA) 浓度 (p < 0.05)。在本研究中，综合考虑三因素方差分析、范围和直接分析，我们发现断奶仔猪的最佳碳水化合物组合是淀粉AM/AP 1:1、NSP 3%、MOS 400 mg/kg。此外，饲喂该组合日粮可促进生长性能和营养物质消化率，增加丁酸产生菌，并在一定程度上改善脂质代谢。这项研究提供了一种评估养猪生产中碳水化合物质量的新方法。
Information about the optimal carbohydrate combination for pigs is scarce. This present study explored the effects of different combinations of starch, non-starch polysaccharides, and mannan-oligosaccharide on the growth performance, nutrient digestibility, and microbial communities in weaned pigs, which contributed a novel way of evaluating the carbohydrate quality of the diet for pigs. The present experiment was conducted to dissect the effects of different carbohydrate combinations on the growth performance, nutrient digestibility, and microbial communities in weaned pigs. The combination was optimized by constructing L9(34) orthogonal design. Three factors include starch (amylose to amylopectin (AM/AP) ratio 2:1, 1:1, 1:2), non-starch polysaccharides (NSP) (1%, 2%, 3%, a mixture of inulin with cellulose by 1:1), and mannan-oligosaccharide (MOS) (400, 800, 1200 mg/kg) were investigated and nine combinations were implemented under different levels of these factors. One hundred and sixty-two weaned pigs were randomly assigned to nine dietary treatments with six replicates per treatment and three pigs per replicate. Results exhibited that different combinations of starch, NSP, and MOS affected the gain to feed (G:F) (p < 0.05), diarrhea incidence (p < 0.10), nutrient digestibility (p < 0.05), microbial communities, and short-chain fatty acid (SCFA) concentrations (p < 0.05). In the present study, taking into account three-way ANOVA, range, and direct analysis, we found that the optimal carbohydrate combination was starch AM/AP 1:1, NSP 3%, MOS 400 mg/kg for weaned pigs. Moreover, feeding this combination diet could promote the growth performance and nutrient digestibility, increase the butyrate-producing bacteria, and to some extent improve lipid metabolism. This study provided a novel way to evaluate the carbohydrate quality in swine production.
