| 摘 要： | 选用272只罗曼褐商品蛋鸡，采用2×3重复交叉试验设计进行了以可消化氨基酸为基础研制产蛋鸡无鱼粉饲粮的研究。结果表明，根据饲料可消化氨基酸含量。采用全植物性蛋白质饲料研制的产蛋鸡无鱼粉饲粮，试鸡的产蛋性能、饲料转化率均达到相同营养水平的鱼粉型饲粮的效果，料蛋比为2．4％。每吨无鱼粉型饲粮可降低原料成本74．96元，平均每只试鸡每天可多获毛利0．0168元，提高11．28％，经济效果良好。

| Abstract: | An experiment of 272 Roman of Variety Brown commercial layer hens was made to ascertain the effect of non-fishmeal diet formulated on the basis of available amino acid on laying performance using repeat cross-over design of 2×3.The results indicate that the effect of the nonfishmeal diet of vegetable protein on laying performance and conversion efficiency are similar to that of the fish meal type diet produced on the equivalent nutritive compositino basis.The ratio of feed to egg is 2.496 and, it can reduce the ingredients cost by 74.96 yuan per ton get more gross profit by 0.0168yuan(RMB)per bird daily on the average and increase economic benefit by 11.28%. So it is quite profitable of feed layer hens. |
