Effect of Broiler Diet Colour on Production Characteristics and Economic Parameters

Abstract

Abstract The purpose of the study was to determine the effect of broiler diet colour on production performance and economic parameters. 360 unsexed one-day-old broiler chicks (ROSS-308) were used, with an average starting weight of 41.8 g. They were randomly distributed over four transactions since the first day of incubation, as follows: T1 = control diet treatment (no addition), T2 = blue diet treatment, T3 = green diet treatment and T4 = red diet treatment, with six replicates per treatment. Each repeater contains 15 birds. The results of the statistical analysis showed a significant superiority (P≤0.05) of the green diet treatment compared to control and blue diet treatments in final body weight, total weight gain, total feed consumption, average carcass weight, herd homogeneity ratio and European productivity efficiency factor. There was a significant decrease in the relative weight of the fabricia gland and abdominal fat in favor of the green diet treatment differences, and there were no significant differences in the total conversion factor and mortality rate and an increase in the value of the net revenue and the percentage of the net revenue for the total breeding period (35) days in the treatments of colour additions to the feed compared to the control treatment.. Adding colors to the ration improved most of the productive traits, carcass traits and economic criteria.
