Abstract

Effect of energy expression system and total amino acid database on economical efficiency of Ross 308 broilers strain was studied by 180 Broiler chicks in a completely randomized design with a 2×3 factorial arrangement. This study was performed with six treatments, three replicates and 10 Broiler chicks in each replicate. Experimental groups included two systems of energy (AMEn and TMEn) and three amino acid database (NRC, Evonik and Ajinomoto) in the periods of starter (1-10 days), grower (11-24 days) and finisher (25-42 days). Dietary formulation with AMEn caused significant increase in feed intake (3983. 2 g) and weight gain (2358. 3 g) of broilers. In 24 and 42 days, dietary formulation with AMEn and then TMEn caused increase in revenue and the cost of broilers’ ration. Dietary formulation according to TMEn caused a significant increase in profitability (3690. 2), gross profit share of revenue (42. 367), profit share of variable costs (74. 100) and gross profit returns (10. 173) as well as a significant reduction in the cost of meat production (2. 19) (P<0. 05). Dietary formulation according to NRC and Evonic database resulted in a significant increase in profitability, gross profit share of revenue, profit share of variable costs and gross profit returns as well as a significant reduction in the cost of meat production (P<0. 05). Based on the results of current experiment, dietary formulation of broilers based on TMEn and NRC and Evonik amino acid database caused relative improvement in net economic return.
