A study was conducted to determine the effects of supplemental choline (CHO) and betaine (BET) on broiler performance, carcass characteristics, corticosterone levels, immune organ weights, intestinal morphology and choline metabolites under thermoneutral (TN: 23.9oC) and heat stress (HS: 28-36oC) conditions. Eight hundred day-old chicks (400 per temperature treatment) were assigned in groups of 10 to each of five dietary treatments: 1 (CON) the basal diet; 2 (CHO500), basal diet plus 500 ppm methyl equivalents added CHO; 3 (CHO1000), basal diet plus 1000 ppm methyl equivalents added CHO; 4 (BET500), basal diet plus 500 ppm methyl equivalents …
