Immunomodulatory and Cortisol Sparing Effect of Tulsi (ocimum Sanctum) in Heat Stressed Broilers
An experiment was conducted in hot summer months with 120 broiler chicks in 5 groups which were given basal diet(BD), BD+vitaminE(200mg/Kg), BD+vitaminE (200mg/kg)+ selenium (0.15mg/ kg),BD+Tulsi(0.25%) and BD+Tulsi(0.5%), respectively. A control group of 24 birds was raised separately in stress free environment. Birds were vaccinated with ND virus and serum was assessed for humoral immune resp...
متن کاملEffects of Thymol and Carvacrol on Productive Performance, Antioxidant Enzyme Activity and Certain Blood Metabolites in Heat Stressed Broilers
The present study was carried out to evaluate the effects of thymol and carvacrol supplementation on performance, immune response, antioxidant enzyme activity and blood parameters of heat stressed broilers. Broilers were fed with commercial diet till 25 d of age, then they were allocated to a completely randomized design with a 3 × 2 factorial arrangement with 6 treatments including 3 levels of...
متن کاملFasting heat production and metabolic BW in group-housed broilers.
Fasting heat production (FHP) is used for characterizing the basal metabolic rate of animals and the corresponding maintenance energy requirements and in the calculation of net energy value of feeds. In broilers, the most recent FHP estimates were obtained in the 1980s in slow-growing and fatter birds than nowadays. The FHP values (n=73; six experiments) measured in 3 to 6-week-old modern lines...
متن کاملeffect of different levels of probiotic (clostat) on performance and immunity of heat stressed broilers in finisher phase
effect of probiotic (clostat) levels on the performance and immune response of heat stressed broilers, was evaluated in a completely randomized design on 144 day-old male ross broiler chicks with four treatments and four replicates (nine birds each). experimental diets were consisted in four levels of probiotic (0, 0.05, 0.1 and 0.2). birds were raised under normal condition till 25 days of age...
متن کاملdetermination the effects of natural antioxidants and fat sources on blood lipids, metabolites, and antioxidant status of heat stressed broilers.
this experiment was conducted to evaluate the effects of turmeric powder (trp), tomato pomace (tp), fat sources (canola oil, soybean oil and tallow) on immune system and jejunum morphometric parameters of heat stressed broiler chickens. five hundred four one-d-old ross broiler were randomly distributed to 36 experimental units and 12 dietary treatments (3 replicates with 12 birds in each). the ...
