This study was conducted to determine the adverse effects of high temperature on some blood parameter of broiler chickens reared under high environmental temperature and evaluating the adding of (propolis and/or digestarom) on diet, three hundred, one-day-old broiler chicks (Rose 308) were distributed equally in to two separated room, thermoneutral (TN) groups and heat stressed (HS) group ( 33 ± 2°C)all over the experiment (42)day. These groups subdivided into five treated groups (30) chick each. They offered a basal diet supplemented with either propolis (2g/kg of diet), or digestarom (150mg/kg), or a mixture of(propolis 2g/kg +digestarom 150mg/kg) or without any diet supplementation with a vaccine or without any diet supplementation without the vaccine. Alanine Transaminase (ALT), Aspartate Aminotransferase (AST), Total Protein and albumin levels were estimated using commercial kits. The result revealed that dietary supplementation with propolis and /or digestarom caused significantly (P≤0.05) increases in blood plasma levels of total protein, globulin, levels of albumin, and significantly reduce (P≤0.05)ALT and AST with or without heat stress as compared to their control groups, while there was a significant reduction in levels of total protein, albumin, globulin (P≤0.05), and significant increase(P≤0.05 in level of AST and ALT. It's concluded that providing broiler’s diets with propolis alone or in combination with digestarom are effective in reducing the adverse effects of heat stress in broilers especially the mixture of propolis with digestarom, which gave the best result.
