The Influence of Turmeric Powder (Curcuma longa) Supplementation to Broiler Diets on Carcass Characteristics, Meat Quality, Hematological Indices and Serum Lipid Profiles

The study intended to assess the impacts of dietary turmeric (Curcuma longa) powder supplementation on carcass characteristics, meat quality, hematological indices, and serum lipid profiles in broiler chickens. Two hundred fortyone-day-old Cobb500 broiler chicks were randomly assigned to four dietary treatments, each with four replicates of 15 chicks. The treatments consisted of 0.0% (control), 0.1%, 0.2%, and 0.3% turmeric powder supplementation. Birds had unrestricted access to food and water throughout the 42-day study. Results showed that turmeric powder at 0.2% and 0.3% concentrations produced better carcass yields (p<0.05) than the control group. The consumption of turmeric in the diet leaded to significant increases in blood hemoglobin levels (p<0.05). Total cholesterol and low-density lipoprotein (LDL) levels, together with albumin/globulin (A/G) ratio decreased (p<0.05) by supplementation, but total protein and globulin levels increased significantly in comparison to the control. Finally, the use of 0.3% turmeric powder in broiler diets proved effective for improving carcass yield and blood parameters while positively affecting blood lipid levels which demonstrates its potential value as a growth promoter and health enhancer for broiler production.
