Nutraceutical Effects of Justicia carnea Leaf Powder Supplementations on Performance, Blood Indices, Heat Shock Protein 70, Oxidative Deoxyribonucleic Acid Damage Biomarkers and Intestinal Microbes of Broiler Chickens, Under Tropical Condition

The main reason preventing broiler chickens from reaching their genetic potential and hurting performance in the tropics is heat stress. This study aimed to ascertain how Justicia carnea leaf powder (JLP) supplementation affects chickens’ performance, blood indices, antioxidant status, gut microflora tropical environments. A completely randomized method was used assign 240 Cobb 500 chicks experimental diets (6 replicates per diet, 10 birds replication). Diet 1 included no supplement (negative control), diet 2 200 mg/kg vitamin C (positive 3 2,500 JLP, 4 5,000 JLP. On day 42, body weight gain (BWG) of fed on significantly higher than those 1. packed cell volume, red count, hemoglobin concentration were control (P<0.05). serum aspartate aminotransferase (AST), alanine (ALT), cholesterol lower 4, compared shock protein 70 (HSP 70) 8-hydroxy-2'-deoxyguanosine (8-OHdG) lactic acid-producing bacteria (LAB) population 1(P<0.05). However, Coliform reduced JLP dietary supplementations enhanced BWG, improved erythrogram AST, ALT, cholesterol, HSP 70, 8-OHdG, caeca but increased LAB population.
