Title: Effect of Dietary Supplementation of Polyalthia longifolia Leaf Meal on Alanine Transaminase (ALT) and Aspartate Transaminase (AST) Levels in Broiler Chicken
Abstract: An experiment was designed to study the effects of dietary supplementation of Polyalthia longifolia leaf meal on alanine transaminase (ALT) and aspartate transaminase (AST) enzyme levels in broiler chicken. A total of one hundred twenty (n=120) day old commercial broiler chicks were procured and randomly distributed in to three treatment group (T1, T2 and T3), each treatment had four replicates with ten chicks per each replicate. A completely randomized design was used and the experiment lasted for six weeks. T1 was served as control. T2 and T3 were fed with Polyalthia longifolia leaf meal at 0.1 and 0.2 per cent levels. Body weight and feed consumption were recorded at weekly intervals. At the end of sixth week, blood samples were collected from four birds each treatment for enzymological assay. The enzymes assayed were alanine transaminase (ALT) and aspartate transaminase (AST). Dietary supplementation of Polyalthia longifolia leaf meal at 0.1% and 0.2% levels significantly (P<0.01) reduced the levels of AST and ALT. It was concluded that Polyalthia longifolia has hepato-protective properties.
