Effect of Supplementation of Herbal Antistress Product and Synthetic Vitamin C on performance of broiler birds under physiological heat Stress
An experiment was carried out on 135 day old Vencob straight run commercial broiler chicks for a period of 42 days (6 weeks). The chicks were randomly divided into three groups (n=45) of three replicates each. Untreated control group (T0) was fed standard basal diet without any supplement, treatment group T1 was supplemented with Ayucee premix at the rate of 100gm/tonne of feed from 0-42 days and treatment group T2 supplemented with synthetic ascorbic acid@100g/tonne of feed. Record of temperature were maintained on daily basis with mean maximum daily temperature of 39±2°C, relative humidity (RH) 82.57 ± 1.40 % (Recorded twice daily at a fixed time by hygrometer). Ayucee premix is a polyherbal formulation containing natural vitamin C and bioflavonoids, scientifically well known for their anti-oxidant and free radical scavenging activities. The mean live body weight (gm) at 6th week was significantly (P<0.05) improved in Ayucee supplemented group T1 birds (2503.66) as compared to control group (2385) and varied non significantly from synthetic ascorbic acid supplemented group T2 birds (2527.16). FCR on 42nd day was significantly (P<0.05) better in Ayucee supplemented group T1 birds (2.08) than synthetic ascorbic acid supplemented group T2 birds (2.12) and control group (2.25). Hematological and biochemical parameters, which were altered under stressful conditions, also improved in Ayucee supplemented group T1 birds.
