大豆中含有一定量的棉籽糖，但棉籽糖对猪的影响研究较少。本试验通过两个试验研究了大豆棉子糖对生长猪生产性能、消化率、体液免疫和肠道形态的影响。在Exp.选用30头体重为21.93 ± 0.43 kg的杜×长×约克郡三元杂交公猪，随机分为3组，分别饲喂对照日粮、对照日粮中添加0.2%和0.5%棉子糖的试验组，试验期21 d。结果表明，日粮中添加0.2%和0.5%棉籽糖显著降低了仔猪的平均日采食量（ADFI）、平均日增重（ADG）和养分消化率（P < 0.05），而0.5%棉籽糖显著提高了料重比（P < 0.05）。在血清指标方面，日粮中添加0.5%棉子糖可降低生长激素水平，提高胰高血糖素样肽-2、免疫球蛋白G、肿瘤坏死因子-α（TNF-α）和白细胞介素-6水平（P < 0.05）。在Exp. 2、将24头体重为38.41 ± 0.45 kg的杂交公猪随机分为3组，分别饲喂对照日粮（自由采食）、棉籽糖日粮（0.5%棉籽糖，自由采食）和与棉籽糖组等量的对照日粮（料对组），试验期14 d。与对照组相比，0.5%棉籽糖组的ADFI显著降低（P < 0.05）。棉籽糖组日增重低于饲料对组，营养物质消化率低于其他2组，十二指肠淀粉酶活性低于其他2组，空肠淀粉酶、脂肪酶和胰蛋白酶活性低于其他2组，血清TNF-α浓度高于其他2组，绒毛高度与隐窝深度比值高于对照组（P < 0.05）。这些结果表明，大豆棉子糖可以减少饲料自愿摄入量和增重，同时改善肠道形态，对免疫功能无明显负面影响。因此，日粮中添加棉籽糖可降低生长猪的采食量和养分消化率，同时诱导体液免疫反应，从而降低生长猪的生产性能。
There are appreciable does of raffinose in soybean, but the impacts of raffinose on pigs are poorly investigated. We used 2 experiments to investigate the influence of soybean raffinose on growth performance, digestibility, humoral immunity and intestinal morphology of growing pigs. In Exp. 1, a total of 30 crossbred (Duroc × Landrace × Yorkshire) barrows (21.93 ± 0.43 kg) were randomly divided into 3 groups, and were fed with the control diet, the control diets supplemented with 0.2% and 0.5% raffinose, respectively, for 21 d. Results showed that the addition of 0.2% or 0.5% raffinose reduced (P < 0.05) average daily feed intake (ADFI), average daily gain (ADG) and nutrient digestibility, and dietary 0.5% raffinose increased the ratio of feed to gain (P < 0.05). For serum indexes, dietary 0.5% raffinose decreased growth hormone and increased glucagon-like peptide-2, immunoglobulin G, tumor necrosis factor-α (TNF-α) and interleukin-6 concentration (P < 0.05). In Exp. 2, a total of 24 crossbred barrows (38.41 ± 0.45 kg) were randomly divided into 3 groups, and were fed with the control diet (ad libitum), the raffinose diet (0.5% raffinose, ad libitum), and the control diet in the same amount as the raffinose group (feed-pair group) for 14 d, respectively. Compared with the control diet, dietary 0.5% raffinose decreased ADFI (P < 0.05). Intriguingly, the raffinose group had lower ADG than the feed-pair group, lower nutrient digestibility, lower amylase activity in duodenum, lower amylase, lipase and trypsin activities in jejunum and higher TNF-α concentration in serum compared with the other 2 groups, and a higher ratio of villus height to crypt depth compared with the control group (P < 0.05). These results showed that soybean raffinose could reduce feed voluntary intake and body gain while improving intestinal morphology without a significant negative influence on immunity. Taken together, dietary raffinose could decrease growth performance by reducing both feed intake and nutrient digestibility while inducing humoral immune response of growing pigs.
