复合氨基酸微量元素螯合物饲料添加剂的研究

本文报道了复合氨基酸微量元素螯合物（简称螯合盐）的制备过程与方法，以及在网箱养鲤中与无机盐添加剂的对比试验结果。研究表明，此法制备的复合氨基酸微量元素螯合物方法简单，产品中氨基酸种类齐全，在本实验条件下微量元素与复合氨基酸螯合效果好。用该产品与无机盐对比养鲤试验表明，添加螯合盐的三个试验组分别比添加无机盐的对照组多增重６８．１％，４６．９％，３７．１％。饲料系数下降率分别为４１．７％，３３．３％，２９．２％。ｔ检验表明，三个试验组与对照组差异显著。

STUDIES OF FEED ADDITION OF COMPLEX AMINO ACID AND MICKOELEMENT CHELATE COMPOUND

The paper introduces the process and method of preparation of complex aminoacid and microelement chelate compound. The experiment of complex amino acid andmicroelement chelate compound was compared with inorganic salt addition in the net cageculture for common carp. The results show it is a simple methed of preparation of complexamino acid and microelement chelate compound. Amino acids in the preduct are complete;the chelative effect of microelements and complex amino acids in the experiments is good,too,The comparative experiments of the product with inorganic salt in the net cage culturefor common carp show the weights of the common carps in the three experimental groupsraised by 68.1%,49%and 37.2%; while the feed coefficients decreased by 41.7%,33.3%and 22 respectively, compared with the control group. The t test indicatesthe difference is significant in the three experimental groups.
