摘要
选择３５日龄健康比利时幼兔４０只，随机分成２组，每组２０只，在基础饲料及管理完全一致的条件下，分别添加按不同方法设计的微量元素添加剂。试验组在分析化验饲料中各种微量元素含量的基础上补加，使之达到营养标准；对照组不考虑饲料中的微量元素含量，按标准另外补加。试验期３０天。结果：试验组和对照组日增重分别为２９．６ｇ和２７．４ｇ，料重比分别为３．３９∶１和３．５４∶１，试验组增重提高８．０３％，差异显著（Ｐ＜０．０５），饲料利用率提高４．２４％，添加剂成本降低２４．７４％，每千克增重降低饲料费０．１６元。试验表明，在设计微量元素添加剂时，应考虑地方性饲料的特点及有关营养含量，以保持营养的平衡性。
healthy young rabbits(35 days old) were devided into two group of 20 each randomly.Mineral additives that were different formula were mixed to basal ration to feed for 30 days under the same management.The mineral contents of feedstuff were considered when trail group's mineral additive formula were designed while that in control's were not.The result showed that ADG(29.6 g/day) and FCR (3.39∶1) of the trail group increased 8.03% and 4.24% respectively compared with the control's (27.4 g/day,3.54∶1) while the cost of feed decreased 0.16 yuan/kg.The conclusion was that mineral contents of feedstuff should be considered when mineral additive formula were designed.
