Effect of dietary supplementation of coriander seed powder on performance, nutrient digestibility, immunity, antioxidant activity and serum parameters of broilers

Abstract

The aim of this experiment was to reduce the antibiotic usage in broiler ration by incorporating the coriander seed powder (CSP). The experiment was conducted from December 2019 to January 2020 with 250 broiler chicks that were randomly divided into 5 treatment groups with 10 replications of 5 birds each. The experimental design consisted of T1: basal diet (BD) without antibiotic; T2: BD + antibiotic (Bacitracin Methylene Disalicylate @ 500 g/tonne); T3: BD + CSP (0.5%); T4: BD + CSP (1.0%); T5: BD + CSP (1.5%). Group supplemented with 1.5% CSP recorded significantly higher body weight gain, feed intake, better feed conversion ratio (FCR) and higher returns compared to antibiotic, control and 0.5 and 1.5% CSP groups. Among all the treatments, significantly better energy retention was recorded in 1.5% CSP group whereas significantly improved protein utilization and dry matter digestibility was noticed in CSP (0.5, 1.0 and 1.5%) supplemented groups. Supplementation of coriander seed powder (CSP) at various levels significantly increased the activity of glutathione peroxidase (GSHPx), glutathione reductase (GSHRx) and superoxide dismutase (SOD) enzymes as well as increased the immune organ weights and antibody response to Newcastle Disease vaccine. Supplementation of 1.5% CSP significantly decreased the serum cholesterol as compared to other groups. Hence 1.5% coriander seed powder can be used as an alternative to antibiotic growth promoter for improving overall performance of broilers.
