Haematological parameters, antioxidant status and carcass analysis of broiler chickens fed diets supplemented with turmeric (Curcuma longa)

Abstract

The experiment was conducted to investigate the effect of turmeric (Curcuma longa) on haematological parameters, ntioxidant status and carcass analysis of broiler chicken. A total of 108-day old broiler chicks were divided into three treatment groups in completely randomised design. The birds were assigned at the rate of 36 birds per treatment in 4 replicates of 9 chicks per replicate. Tumeric powder was supplemented to the feed at the rate of 0%, 0.5% and 1.0% throughout the experiment (8week). All data generated were subjected to one-way analysis of variance. Results showed that haematological parameters like PCV, RBC, Hb and monocyte increased as the level of turmeric supplementation increases. The antioxidant enzymes glutathione-peroxidise (GPx), superoxide dismutase (SOD), catalase (CAT) and total antioxidant activity (TAA) positively increased with increase in the turmeric supplementation. Increasing level of turmeric supplementation significantly (P<0.05) decreased live weights, dressed weights and eviscerated weights of broiler chicken. Some of relative internal organ weights were affected by turmeric supplementation except heart, kidney, lung and pancreas. It was concluded that the turmeric can be added to the diets of broilers chicken up to the level 1.0% and protect cell from excess production of reactive oxygen species also it has the potential to improve immune response in broiler chicken.
