The study was aimed at determining the effects of Vitamin C and electrolyte on growth and meat yield of broilers in ahot humid environment. A total of 60 straight run day old Cobb 500 broilers were reared up to 35 days of age and fedad libitum on a starter diet up to 12 days and thereafter, on a grower diet. The broilers were divided into 4 treatmentgroups. One group (15 broilers) without Vitamin C and electrolyte supplementation was considered as control. Inother three groups were provided 135ppm Vitamin C, 1250ppm electrolyte and 135ppm Vitamin C + 1250ppmelectrolyte in drinking water respectively as supplement. Feed intake, body weight, feed conversion and survivabilitywere similar in broilers that received different levels of Vitamin C and electrolyte supplementation in drinking water.Feed cost per broiler and per kg broiler increased due to the addition of Vitamin C and electrolyte. Dressing yield,breast meat, total meat and wing meat were (P<0.05) higher in broilers that received Vitamin C in drinking water thanthose of control, electrolyte and Vitamin C + electrolyte supplemented groups. No differences (P>0.05) were found inbreast: dark meat, thigh meat, drumstick meat and abdominal fat which could be attributed to either Vitamin C orelectrolyte supplementation. It implies that deficiency of Vitamin C may be related to reduce meat yield of broilers in ahot humid environment. However, further experiment using several doses of Vitamin C with large number of broilersmay be conducted to confirm the appropriate doses of supplementation
