| چکیده | ||
| An experiment was conducted to study the effects of substitution soybean meal (SBM) with canola meal (CM) and formulated diets based on total and digestible amino acid on performance, egg quality, organs weight and blood parameters of laying hens from 73 to 83 weeks of age. A total of 128 laying hens were distributed by completely randomized design in a 2×2 factorial arrangement with 2 protein sources (soybean meal and 30% soybean replaced by canola meal), and diets were formulated based on two types of amino acid recommendation (total or digestible). Four experimental diets were formulated with four replicates and 8 birds in each. Increased egg weight, egg mass and improved feed conversion ratio (FCR) were shown by soybean than canola meal in the diet (P0.05) by treatments. The results of this study have shown that soybean meal improved performance than canola meal as well as soybean meal diet formulated on digestible amino acid had better effected on performance than total amino acid arrangement in diet. | ||
