中草药饲料添加剂——蛋壳素对蛋鸡产蛋性能及蛋壳质量的影响

AFFECT OF EGGSHELL ELEMENT ON LAYER PRODUCTION PERFORMANCE AND EGGSHELL QUALITY

试验选用正在产蛋的800只罗曼鸡群,分组饲喂中草药饲料添加剂——蛋壳素,对生产性能进行测定,试验结果表明,在罗曼产蛋日粮中添加0.02%的蛋壳素与对照组(不添加蛋壳素组)比较:①产蛋量提高6.41%～6.5%;②平均蛋重每枚增加0.55～1.1g;③破蛋率降低2.5%;④饲料转化率提高6.9%～7.28%。另外,蛋壳表面光滑、鲜艳、无沙皮蛋。

Eight hundred of Lohmann laying hens,divided into groups,were fed with eggshell element (the Chinese traditional medicine additive)and their production performance were determined.The result in test group with0.02%eggshell element ,compared with the control,indicated that:①the egg production quantity increased by6.41%～6.5%,average egg weight increased by0.55～1.1g,the rate of broken egg reduced by2.5%and the feed conversion rate improved by6.9%～7.28%.In addition,the eggshells’surface were smooth,bright –colored and not sandy.
