EFFECT OFBETAINE  LEVELS ON BROILER PERFORMANCE  UNDER CYCLIC HEAT STRESS
ABSTRACT: This study was carried out at the Research Poultry Farm, Faculty of Agriculture, Sohag University,Egypt. It was designed to study the effect of betaine supplementation on broilers performance under cyclic heat stress. A total number of 375 Ross, one day-old were equally divided into five groups (75 birds/group) with three replicates (25birds / replicat). In the first group, birds ... Read more
