                    Abstract

                    Gedi (Abelmoschusmanihot (L.) Medik) isa native herbal and vegetable plant in Northern Sulawesi-Indonesia. Itcontains high crude protein,lysine, crude fiber, mucilage, calcium, steroid, flavonoid, and total phenol,whichmay offer beneficial effects as poultry feedstuff on a special production trait, such as cholesterol-less meat and nutritional strategies to reduce heat stress. The literature of gedi leaves utilization as feedstuff in broiler chicken dietis scarce. In this experiment, the effects of gedi leaves on the physiological responses, specific growth rate(SGR),and carcass traits of broiler chicken exposed to high ambient temperature was investigated. Total of 100 unsexed Cobb CP 707 broiler chicken wererandomly allocated to 4 dietary treatments: diets containing 0 (control), 5, 10, and 15% gedi leaves.To induce chronic heat stress, the temperature was increased to 33.5ºC with 63% relative humidity for 5 h daily starting from d 1 until d 35. At d 36, onechicken per pen were sampled for carcass traits and abdominal fat. Feedingup to15% gedi leaves dietreducedfeed intake, weight gain,and SGR (p˂0.01).Feed consumption ratioof chicken fed up to 10% gedi leaves dietwas better compared to control andless GE obtained for R3 treatment. Data suggested lower dressing percentage (p˂0.036) but still was good category and significantly lower abdominal fat (p˂0.01) for feeding up to 15% gedi leaves diet. These results indicated that gedi leaves in diet under heat stress enhanced the performance of broiler chicken for functional food and may benefit after processing the mucilage of gedi leaves. Key Words: Chickens, Heat stress, Gedi leaves, Growth performance, Carcass traits
