摘　　要：ＳＰ－９６为一种具有重要生理活性物质的营养添加剂。在产蛋鸭饲料中添加一定剂量的ＳＰ－９６营养添加剂，存活率提高３．９７百分点；产蛋率提高３．３３百分点；蛋增重３．６５克／个；全蛋水分下降１．８百分点；蛋黄水分下降３．１８百分点；粗蛋白量提高０．５百分点；粗脂肪量提高１．９２百分点；蛋清中１７种氨基酸（含７种必需氨基酸）含量增加；全蛋灰分高出０．００８百分点；蛋清中锌含量提高０．１毫克／千克，锰含量下降０．１毫克／千克，钴。P-96 is a nutritional additive with important physiological activities.An experiment was carried out with the check group (without SP-96) and the trial group (adding a certain dose of SP-96 to the feed of egg-laying duck).The results showed that a. the survival rate,egg-laying rate,coarse protein weight,coarse fat weight and ash content of a whole egg increased by 3.97%,3.33%,0.5%,1.92% and 0.008%,and water content of a whole egg as well as of yolk decreased by 1.8% and 3.18% in the trial group,respectively ,compared with those in the check group;b.in the trial group,the egg weight and zinc content in egg white were 3.65 g/each and 0.1mg/kg higher than,and manganese content in egg white was 0.1mg/kg lower than those in check group,respectively; c. each kind of amino acid,especially 7 necessary amino acids in egg white obviously increased in the trial group;and d.there was no difference between the two groups in terms of cobalt and selenium content in egg white.
