Feeding Strategies for Prolific Sows高产母猪的饲养策略;Changes in the Swine Industry (1980-2005)养猪工业的变化 (1980-2005);Feed Modern Genotypes Differently 现代基因型猪饲养与过去的不同;Conserve Body Tissue 体组织储备;Consequences of Poor Sow Nutrition母猪营养缺乏的后果; Formulate Diets for Specific Stages of Production 按生产阶段配制日粮; ;Locomotor problems are a common reason for culling and it is important to ensure adequate intakes of calcium and phosphorus. 运动问题是造成母猪淘汰的主要原因, 但它对保证母猪能摄取足够的钙磷也非常重要。 Several research trials have indicated that the calcium and phosphorus requirements for maximal bone mineralization are higher than the requirements for maximal growth rate. 很多实验研究表明，猪的最大骨质矿化要比最快生长率对钙磷的需要量更高。;In addition to higher levels of calcium and phosphorus, there is antidotal evidence that supplementing the gilt developer diet with higher levels of copper, zinc, iron, iodine and manganese will increase body reserves of these minerals and may enhance future reproductive performance. 后备母猪的日粮除要求额外高水平的钙、 磷之外如能再补充高水平的铜、 锌、铁、碘、锰微量元素，这将 有助于提高母猪体内对这些矿物 质的储备从而能改善以后的繁殖 表现。; Typical Gilt Finisher Developer 育肥猪 后备母猪 常量元素 Macrominerals (Total) 钙 Calcium % 0.60 0.75 磷 Phosphorus % 0.50 0.65 有效磷 Avail phosphorus % 0.20 0.40 食盐 Salt % 0.33 0.40 微量元素 Microminerals (Supplemented) 铁 Iron mg/kg 50 150 铜 Copper mg/kg 10 15 锌 Zinc mg/kg 90 150 碘 Iodine mg/kg 0.14 0.28 硒 Selenium mg/kg 0.30 0.30 锰 Manganese mg/kg ---- 20 ;The vitamin needs of the reproducing female are also greater than those of the terminal animal. 繁殖母猪的维生素需要量比育肥猪高。 The typical vitamin premix used in the finishing barn should be replaced with a “breeder” vitamin premix. 要用种猪维生素预混料来代替常用育肥猪饲养期的典型维生素预混料。 The breeder premix should contain elevated levels of the fat soluble vitamins A, D, and E and the water-soluble vitamins with special attention to choline, biotin, pyridoxine and folic acid which are
