Dissertation note The purpose of study was to characterize the efficacy of different anti-stressors on broilers reared during heat stress. The study was conducted at Poultry Research and Training (PRTC) Centre, Ravi Campus Pattoki, in hot-humid weather (July-August), University of Veterinary and Animal Sciences, Lahore. A total of 200 day old broiler chicks (Cobb 500) were procured from hatchery and arranged according to completely randomized design; assigned 05 dietary treatments (control, Betaine 2g/kg, Chia seed 5g/kg, Potassium chloride 2g/kg and vitamin C 600mg/kg). Feed and water was provided ad-libitum throughout the experimental period. Temperature and humidity were recorded three times a day. At day 7th, 17th, 36th and 42nd, four blood samples were taken from each treatment. Serum was separated to evaluate the immune response against New-castle disease. Daily feed intake and weekly body weight were recorded. At 42nd day, four birds from each treatment were randomly selected and slaughtered to record carcass characteristics; blood samples were collected to estimate blood glucose and cholesterol level of different treatment birds. Data thus collected was analyzed through one-way ANOVA technique (Steel et al. 1997). Comparison of means were worked out through Duncan’s Multiple Range test (DMR) with the help of SAS 9.1.
Results of present study indicated that betaine group significantly (P< 0.05) improved the growth parameters; body weights and feed conversion ratio of broilers during heat stress, feed efficiency, point spread, performance index production number livability, and uniformity does not significantly (P<0.05) effected but apparently improved, mortality rates reduced in this group. Addition of chia seed to the diet resulted in to significantly (P< 0.05) better feed consumption and immune response against new-castle disease in heat stressed broilers. Vitamin C supplementation significantly (P< 0.05) improved the physiological perameters of broilers by reducing the cholesterol and glucose levels in serum samples of broilers reared during acute heat stress. Carcass characteristcs were also improved in heat stressed broilers fed on betaine supplemented diets. Dressing %, thigh yield%, intestine %, pancrease %, thymus %, breast width (cm) and shank length (cm) significantly increased (P< 0.05) while, breast meat yield %, abdominal fat %, giblets %, bursa%, spleen% and keel length (cm) were not significantly (P> 0.05) effected but apparently improved in this group. Betaine group also improved economics in heat stressed broilers.
Conclusion:
Based upon the findings of present study it can be concluded that:
1. Supplementation of betaine in diet of heat stressd broilers proved comparatively more efficient than other anti-stressors in improving growth parameters and carcass characters of broilers reared during hot-humid climate, hence remained more economical.
2. The organic anti stressor “Chia seed” showed better antibody titer against new castle disease and also improved the weight of immune organs.
3. Supplementing vitamin C in diet decreases the serum glucose and cholesterol level in broilers.
