摘要

益生菌与多酚抗氧化剂之间的相互作用有可能增强动物的健康。本研究考察了补充没食子酸丙酯和植物乳杆菌对北京鸭生长、肠道形态、抗氧化能力和免疫功能的影响。总共 128 只雄性北京鸭（7 日龄）被分配到四个处理组，每组八个重复。这些鸭子以玉米-大豆为基础饲料（对照组），添加没食子酸丙酯（100 毫克/千克）、植物乳杆菌（4 × 109 CFU/千克）或两者，喂养 5 周。日粮中添加没食子酸丙酯和植物乳杆菌对采食量没有显著影响（P > 0.05），但会提高平均日增重（P 0.05）。观察到补充剂提高了总超氧化物歧化酶活性（P 0.05）。添加植物乳杆菌后，血清免疫球蛋白 G 有所增加（P 0.05）。补充植物乳杆菌后，IgA 和 IgM 的浓度没有变化。总之，膳食中添加没食子酸丙酯、植物乳杆菌或两者，可提高小肠绒毛的高度，改善北京鸭的生长速度。没食子酸丙酯和植物乳杆菌对绒毛高度和血清总超氧化物歧化酶活性的协同作用超过了每种添加剂对北京鸭的单独作用。

Effects of dietary propyl gallate and Lactobacillus plantarum addition on growth, intestinal morphology, antioxidant capacity, and immune functions of Pekin ducks

The interaction between probiotic bacteria and polyphenol antioxidants can potentially enhance animal health. The present study examined the effects of propyl gallate and Lactobacillus plantarum supplementation on the growth, intestinal morphology, antioxidant capacity, and immune functions of Pekin ducks. A total of 128 male Pekin ducks (7-day-old) were allocated to four treatment groups with four replicates of eight birds each. The ducks were fed the corn-soybean based diet (the control), supplemented with either propyl gallate (100 mg/kg), Lactobacillus plantarum (4 × 10⁹ CFU/kg), or both, for 5 weeks. Dietary supplementation with propyl gallate and Lactobacillus plantarum had no significant effect on feed intake (P > 0.05), but increased average daily gain (P < 0.05). Lactobacillus plantarum also reduced the feed/gain ratio (P < 0.05). Villus height (VH) in the duodenum and ileum was increased by supplementation, while only propyl gallate supplement increased VH in the jejunum (P < 0.05). Supplementation had no effect on small intestine crypt depth (P > 0.05). Enhanced total superoxide dismutase activity was observed with supplementation (P < 0.05), but no effects were seen on catalase, malondialdehyde, total antioxidant capacity, and glutathione peroxidase values (P > 0.05). Serum immunoglobulin G was increased with Lactobacillus plantarum (P < 0.05), but not with propyl gallate (P > 0.05). No change in IgA and IgM concentrations was observed with supplementation. In conclusion, dietary supplementation with propyl gallate, Lactobacillus plantarum, or both, enhanced the villus height of the small intestines, improving the growth rate of Pekin ducks. The synergistic effects of both propyl gallate and Lactobacillus plantarum on the villus height and serum total superoxide dismutase activity surpassed the individual effects of each supplement in Pekin ducks.

期刊介绍： Editorial board animal attracts the best research in animal biology and animal systems from across the spectrum of the agricultural, biomedical, and environmental sciences. It is the central element in an exciting collaboration between the British Society of Animal Science (BSAS), Institut National de la Recherche Agronomique (INRA) and the European Federation of Animal Science (EAAP) and represents a merging of three scientific journals: Animal Science; Animal Research; Reproduction, Nutrition, Development. animal publishes original cutting-edge research, ''hot'' topics and horizon-scanning reviews on animal-related aspects of the life sciences at the molecular, cellular, organ, whole animal and production system levels. The main subject areas include: breeding and genetics; nutrition; physiology and functional biology of systems; behaviour, health and welfare; farming systems, environmental impact and climate change; product quality, human health and well-being. Animal models and papers dealing with the integration of research between these topics and their impact on the environment and people are particularly welcome.
