Abstract

High environmental temperatures may cause heat stress in poultry. This may increase water consumption, decrease feed consumption and in turn, decrease production level.  This experiment was conducted to study the supplementation of vitamin C as anti heat-stress agent of broilers. In this research, were used 72 broilers 21 days old. The treatment are two kinds. The first, two poultry house temperatures (32 and 240C as warm temperature and cool temperature respectively) and second, four levels suplementation of vitamin C (0, 250, 500 and 750 ppm of ration as C0, C250, C500 and C750 respectively). Variables measured are feed consumption, body weigh gain, content of abdominal lipid and feed convertion. The data collected were analized with a split plot design in completelly random design and continued with the contrast-orthogonal test when significantly different The result indicated that vitamin C significantly (P<0.05) increased feed consumption and body weigh gain. The warm temperature significantly (P<0.05) decreased feed consumption and body weigh gain. Feed convertion of C250, C500 and C750 in warm temperature were significantly (P<0.05) lower than C0. The supplementation of 250 ppm vitamin C (C250) was most efective as anti heat-stress agent in broilers kept at warm temperature. Key Words: Vitamin C, Broiler, Heat-Stress

Abstract

Oxidative stress (a condition where oxidant -free radical- activity dominates the antioxidant activity) in poultry may be caused by heat stress from high environmental temperature. In this research, antanan (Centella asiatica) and vitamin C was utilized as anti heat-stress agents for broilers. One hundred and twenty male broilers of 2 – 6 weeks of age were kept at 31.98 ± 1.940C poultry house temperature during the day and 27.36 ± 1.310C at night. The treatments consist of two kinds: two levels of vitamin C (0 and 500ppm) and three levels of antanan (0, 5 and 10% of diets). The data colected was analized for variance with a factorial in completely randomized design of 2 x 3 (2 levels of vitamin C, 3 levels of antanan) and continued with contrast-orthogonal test when applicable. The results indicated that the treatments of antanan 5% without vitamin C (A5C0), antanan 10% without vitamin C (A10C0), vitamin C 500ppm without antanan (A0C500), combination of A5 and C500 (A5C500), and combination of  A10 and C500 (A10C500) significantly (P<0.05) decreased the level of liver malonaldehida (MDA), carcass lipid and plasma cholesterol.
