Effect of the Supplementation of Plant Extracts Based Additive in Broiler Chicken Diets on Productive Performance, Carcass Yield, and Meat Quality

The study aimed to evaluate the effect of supplementation an additive based on plant and spice extracts in broiler chicken diets productive performance, carcass yield, meat quality. 704 male chicks were distributed a completely randomized experimental design with 4 treatment, replicates 44 chickens each. consisted Diet 1: Control diet; 2: diet + antibiotic growth promoters (AGP); 3: vegetable (100 g/ton) 4: (150 g/ton). used carvacrol, cinnamaldehyde, eugenol extracted from oregano, cinnamon, cloves. vegetal did not affect (p>0.05) chickens’ performance or yield. lipid peroxidation (MDA nmol/mg protein) natura was decreased (p<0.05) for broilers supplemented extracts. 100 150 g/ton characteristics, quality, inhibited MDA production broilers’ meat.
