Abstract This study was carried out in a broiler farm under the supervision of Animal Production Department, Faculty of Agriculture, Tanta University during the period from October to November 2019 to investigate the effects of supplementation of calcium propionate at different levels on growth performance, blood biochemical profiles and immune response of broiler chicks. Two hundred and forty one-day-old unsexed avian broilers chicks (1: 35 old day)were used in this experiment. Birds were wing banded, individually weighed to the nearest gram, and randomly distributed into four equal experimental groups; with three replicates of 20 chicks each. The average initial body weights of the treatment groups were nearly similar with no observed significant differences. The chicks were offered two corn-soybean meal basal mash diets that were formulated to meet or exceed the Nutritional Requirement of growing chicks as recommended by the National Research Counci (NRC, 1994 The experimental designed was included |
