  4. Health Management健康管理 • All-in/All-out pig flow 全进全出制度 • Weaning age 断奶日龄 • Biosecurity 生物安全 • Sanitation卫生 • Vaccines 疫苗 • Eradication/ Depopulation-Repopulation 根除/灭绝种群-恢复种群

  5. Dietary Factors日粮因素 • Purposes 目的 • Improve health 提高健康水平 • Improve performance 改善生长性能

  6. Mechanisms of Dietary Factors日粮因素的作用机理 • Alter microbial populations in the digestive tract 改变动物消化道微生态区系平衡 • Pathogens 致病菌 • Commensal 共生菌 • Immune effects 免疫反应 • Others? 其他?

  7. Dietary Factors日粮因素 • Energy & protein sources 能量和蛋白来源 • Additives 添加剂 • Feeding management 饲养管理

  8. Energy & Protein Sources能量和蛋白来源 • Spray-dried plasma 喷雾干燥血浆 • Fibrous ingredients 纤维原料 • Milk protein products 乳蛋白产品 • Lactose 乳糖 • Egg products, conventional常规蛋制品

  9. Additives (1)添加剂 (1) • Mannan oligosaccharides 甘露寡糖 • Zinc & Copper 锌和铜 • Immune egg products 免疫蛋制品 • Acids 酸化剂 • Fructo-oligosaccharides 果寡糖 • Other oligosaccharides 其他寡糖

  10. Additives (2)添加剂 (2) • Direct-fed bacteria (probiotics) 直接饲喂微生物 (益生素) • Yeasts/yeast products 酵母/酵母产品 • Essential oils 香精油 • Bacteriocins 细菌素 • Bacteriophage 噬菌体 • Enzymes 酶制剂 • Nucleosides 核苷酸

  11. Feeding Management饲养管理 • Low-protein diets 低蛋白日粮 • Restricted feeding 限饲 • Fermented liquid feed 发酵液体饲料

  12. This Presentation报告内容 • Spray-dried plasma 喷雾干燥血浆 • Mannan oligosaccharide 甘露寡糖 • Zn & Cu 锌和铜 • Fiber 纤维 • Low-protein diets 低蛋白日粮 • Immune egg products 免疫蛋制品

  13. Meta-Analysis荟萃分析 • Method of combining experiments 综合多个试验结果进行分析的一种方法 • Power 势函数 • Inference space 推论空间 • Problem: “Negative” results sometimes not published 问题: “负面” 结果有时未发表

  14. Spray-Dried Plasma喷雾干燥血浆 • Use for short time 短期使用 • Increases feed intake 提高采食量 • Appears to affect immune system 改善免疫系统 • May alter microbial populations 调节微生物区系

  15. Spray-Dried Plasma喷雾干燥血浆 Mean=26.8% Van Dijk, 2001

  16. Spray-Dried Plasma喷雾干燥血浆 E. Coli Challenge

  17. Spray-Dried Plasma喷雾干燥血浆 • Dramatically increases growth rate 显著提高生长速度 • Protects against disease 提高抵抗疾病能力

  18. Mannan Oligosaccharide (MOS)甘露寡糖 (MOS) • Made from yeast cell wall 从酵母细胞壁提取

  19. MOS - Starting Pigs甘露寡糖 – 仔猪 Mean=4.4%; P=0.00003 Miguel et al., 2004

  23. Mannan Oligosaccharide (MOS)甘露寡糖 (MOS) • Improves growth performance of young pigs 改善仔猪生产性能 • Improves sow performance 提高母猪繁殖性能 • Changes microbial populations 调节微生物区系平衡 • Affects immune system 影响免疫系统

  24. Zn & Cu锌 和 铜 • Increase growth rate 促生长 • Additive 添加剂 • Zn – disease resistance 锌 – 抗病性 • Environmental concerns 环境问题 • Organic Cu, not Zn 有机铜, 非有机锌

  25. Zn & Cu锌 和 铜 * Perez et al., 2006

  26. This Presentation报告内容 • Spray-dried plasma 喷雾干燥血浆 • Mannan oligosaccharide 甘露寡糖 • Zn & Cu 锌和铜 • Fiber 纤维 • Low-protein diets 低蛋白日粮 • Immune egg products 免疫蛋制品

  27. Fiber纤维 • Fermentable carbohydrates 可发酵碳水化合物 • Good or bad?? 好或坏?? • Substrate for commensals, which compete with pathogens 与病原体竞争共生菌的底物 Substrate for pathogens 病原体的底物 • Nonfermentable carbohydrates 不可发酵碳水化合物 • Advantages? 优点?

  28. Fiber纤维 * Adapted from Durmic et al.(1998)

  29. Pelleting制 粒 • May convert insoluble NSP to soluble NSP 不可溶性非淀粉多糖转化为可溶性非淀粉多糖

  30. DDGS & Ileitis玉米酒糟与回肠炎 Adapted from Whitney et al., 2002

  31. Our Results结 果 a ab b b Perez et al., 2006

  32. Low-Protein Diets低蛋白日粮 • High protein levels in lower gut lead to: 高蛋白日粮导致后段消化道: • Undesirable microbial growth 有害微生物增殖 • Diarrhea 腹泻

  33. Low-Protein Diets低蛋白日粮 Adapted from Ajinomoto 来源: 味之素公司

  34. Immune Egg Products免疫蛋制品 • Immunize hens against pig pathogens 通过对母鸡免疫，产生免疫蛋制品，抵抗猪病原体 • Provide passive immunity to pigs 使猪产生被动免疫

  35. Immune Egg Products免疫蛋制品 E. Coli infection; Mean=-42.4%
