【摘要】 用生长肥育猪进行4批饲养对比试验。每批的试验组与对照组均按营养需要喂给组份相同、营养指标相等的日粮。只是试验组日粮用微量元素赖氨酸螯合物代替了对照组日粮中的等量硫酸盐形式微量元素和外加的等量赖氨酸。结果表明:微量元素赖氨酸螯合物是优良的营养性饲料添加剂,可提高日增重6.4%,改善饲料效率7.0%。鳌合物的成本增加部分只占日粮成本的0.5%,其增加成本的投入:产出比达到了1:19。更多还原

【Abstract】 Four trials were conducted to study the effect of trace-lysine-chelate on performance of growing pigs. The control and trial groups received the same basal diet, included the same feed ingredient and had equal nutrition index. But the trial diet used trace-lysine-chelate instead of the trace sulfate and added lysine in equal content.The result showed that: trace-lysine-chelates are excellent nutritive feed additives, trace-lysine-chelate significantly increased average daily gain by 6.4% and improved feed efficiency by 7.0%. The increased cost of chelate was only 0.5% of diet. Its input/output ratio was very high, come to 1:19.更多还原
