本试验研究了妊娠日粮中添加不同含量的小麦糊粉(0、15%、30%)对母猪繁殖性能、餐后饱腹感、应激状态和刻板行为的影响。选用84头长白×约克夏母猪(胎次为4.87±1.32),按胎次和体重随机分成三个等能等氮日粮处理组。结果表明,与对照组(0)相比,饲喂Wa日粮的母猪血清中YY(PYY)(P<0.05)和GLP-1(P<0.05)水平显著高于对照组(P<0.05),唾液皮质醇(P<0.01)水平低于对照组(P<0.01)。重要的是,与对照组相比,只有15%Wa组的总抗氧化能力(T-AOC)浓度较高(P<0.05),坐位比例(P<0.05)和死产率(P<0.01)较低。因此,与对照组相比,15%WA组每头活产仔猪的生产成本(6.9美元对7.6美元)或每头健康出生的仔猪的生产成本(7.4美元对7.9美元)下降。总体而言,妊娠日粮中添加15%的Wa有助于提高母猪的餐后饱腹感,缓解应激状态,降低死胎率。本研究为应用乳酸菌素部分替代常规饲料成分提高母猪繁殖性能提供了参考。
This study investigated the effects of different amounts of wheat aleurone (WA) (0, 15%, 30%) inclusion in gestation diets on the reproductive performance, postprandial satiety, stress status and stereotypic behaviors of sows. A total of 84 Landrace × Yorkshire sows (parity 4.87 ± 1.32) at breeding were randomly allotted to one of the three isoenergetic and isonitrogenous dietary treatments based on parity and body weight. The results showed that, compared with the control (0), sows fed the WA diet had a higher serum concentration of peptide YY (PYY) (P < 0.05) and glucagon like peptide-1 (GLP-1) (P < 0.05) and a lower concentration of saliva cortisol (P < 0.01). Importantly, compared with the control group, only the 15% WA group had a higher concentration of the total antioxidant capacity (T-AOC) (P < 0.05), lower proportions of sitting (P = 0.05) and stillbirth rates (P < 0.01). Accordingly, the production cost per piglet born alive ($ 6.9 vs. $ 7.6) or per piglet born healthy ($ 7.4 vs. $ 7.9) declined in the 15% WA group versus the control group. Overall, 15% WA inclusion in gestation diets contributed to enhancing postprandial satiety, alleviating stress status and decreasing stillbirth rate of sows. This study provides a reference for the application of WA as a partial substitute for conventional feed ingredients to improve sows’ reproductive performance.
