Alteration in serum biochemical parameters due to garlic (Allium sativum) supplementation in broilers diets

This study was undertaken to evaluate the effect of Allium sativum supplementation through drinking water and feed on some serum biochemical parameters of broiler chickens. For this purpose, a 42 day’s feeding trial was conducted in a completely randomized design (CRD) on growing broiler chicks. Garlic (Allium sativum) was supplemented at graded levels as juice (2.25 and 3%) through drinking water and as powder (0.75 and 1%) through feed to experimental treatment T2, T3, T4 and T5, respectively with three replicates of 10 broiler chicks each for a period of 42 days starting from one day of age. The serum glucose level, serum total cholesterol, serum glutamate oxaloacetate transaminase (SGOT) concentration, and serum glutamate pyruvate transaminase (SGPT) concentration decreased significantly (P≤0.05) due toA. sativum supplementation in different treatment group as compared to control group at 28th and 42nd days. Serum alkaline phosphatase (ALP) levels of the birds of different treatment did not reveal any significant impact of A. sativum supplementation on the 28th day but significant reduction was noted as compared to control group on the 42nd day.   Key words: Garlic, serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), serum alkaline phosphatase (ALP), serum glucose.
