氨基酸微量元素螯合物对异育银鲫生长及其品质的影响

试验研究了氨基酸微量元素螯合物对异育银鲫生长及其品质的影响。结果表明,①氨基酸微量元素螯合物替代无机微量元素能显著促进异育银鲫生长,提高饲料利用效率,其中,以65%替代无机微量元素的促生长效果最好,饲料利用效率最高,日特定生长率和饲料利用效率分别增加25.37%和26.32%。②用氨基酸微量元素螯合物替代无机微量元素后,鱼体水分、灰分含量无显著差异,以65%替代无机微量元素后,鱼体蛋白含量提高1.75%;鱼体脂肪含量在35%、50%、65%替代无机微量元素后,均有增加。③氨基酸微量元素螯合物35%、50%、65%替代无机微量元素,对鱼体肥满度没有产生影响,但内脏比均增加。④氨基酸微量元素螯合物以35%、50%、65%替代无机微量元素后,提高了成活率、降低了养殖饲料成本。⑤在氨基酸微量元素螯合物基础上再添加黄霉素,具有更好的促生长效果和更高的饲料利用效率。

Effects of element chelates of amino acids on growth and quality of crucian carp

The experiment studied the effects of aminoacid chelates on growth and quality of crucian carp. The results showed that, ①after element chelates of amino acids replaced 65% of inorganic elements(including iron, zinc, copper and manganese) in diets, it remarkably improved growth and feed utilization of crucian carp than inorganic elements did , and SGR(special growth ratio) and feed efficiency was improved by 25.37%, 26.32%, respectively.②There were no significance of moisture and ash of fish between experimental groups fed amino-acid chelates and control group fed inorganic element. ③After element chelates of amino acid replaced dietary 65% of inorganic elements, crude protein of fish was increased by 1.75%; and after it replaced 35%, 50%, 65% of inorganic elements, crude fat and survival ratio of fish were all improved and costs of culture were all decreased.④There were better growth and feed efficiency when diets of crucian carp were supplemented flavomycin premix on the base of supplementation of element chelates of amino acids. plant lactobacillus had the resistant to 10 of the 32 kinds antibacterial; and 4 strains sporangium bacilliform bacteria were sensitive to 32 kinds antibacterial except bacitracin. This test results have scientific guidance meaning for developing and application in livestock and poultry production of microbe animal feed additive.
