Abstract: |
| Present study was done to study the effects of lowering soybean meal in broilers diet and determination of the best level of soybean meal substitution by Aminomix, a product of Ofogh Kurosh Company. The project was done by using a total of 750 one-day-old broiler chicks (ROSS 308, mixed-sex) in a completely randomized design with 5 treatments, 5 replicates, and 30 birds each replicate. The experimental treatments was included: Control diet (basal diet without Amino-mix), diet contained 1 % Amino-mix without lowering soybean meal level, diet contained 1 % Amino-mix and 1.6 % lowering the soybean meal level, diet contained 1 % Amino-mi and 3.3 % lowering the soybean meal level, diet contained 1 % Amino-mix and 5 % lowering the soybean meal level. The results showed that using Amino-mix in diet as an additive caused a reduction in FCR during 1 to 10 and 11 to 24 days of age, however, it did not have significant effect on broilers performance such as body weight, feed intake, and feed conversion ratio during 1 to 41 days of age. Also, the experimental treatments did not have significant effect on antibody titer against Newcastle and Influenza viruses, total protein, globulin, albumin, AST, cholesterol, tri-glyceride, HDL, LDL, WBC count, and also heterophile, lymphocyte, monocyte, eosinophil, H/L (stress biomarker), carcass yield, thigh, back + neck, gizzard, bursa of fabricius, gallbladder, liver, and heart of broilers on 42 d (P>0.05); |
