One hundred ninety-two female broiler chickens were randomly distributed into 16 experimental treatments as a result of the combination of 4 levels of dietary polyunsaturated fatty acids (PUFA) (15, 34, 45, and 61 g/kg) and 4 levels of supplementation with alphatocopheryl acetate (alpha-TA) (0, 100, 200, and 400 mg/kg), to determine the modification of the(More)
The objective of the present study was to evaluate the pattern of accumulation of alpha-tocopherol (alpha-Toc) in egg as a response to dietary supplementation with 200 mg/kg diet of alpha-tocopheryl acetate (alpha-TA) and whether the inclusion of dietary oils with different fatty acid (FA) composition affected this parameter. Forty hens were randomly(More)
A 2 x 2 x 2 factorial experiment was planned to study the influence of dietary fat source (linseed oil or sunflower oil) and dietary doses of alpha-tocopheryl acetate (alpha-TA) (0 or 200 mg/kg of feed) and canthaxanthin (CX) (0 or 5 mg/kg of feed) on fatty acid (FA) composition and lipid oxidation of fresh and spray-dried eggs. Dietary supplementation with(More)
The present study was carried out to evaluate the influence of increasing amounts of dietary polyunsaturated fatty acids (PUFA) and alpha-tocopheryl acetate (alpha-TA) supplementation on lipid oxidation of raw and cooked thigh meat stored under refrigeration. One hundred ninety-two female, 1-d-old, broiler chickens were randomly distributed into 16(More)
The antioxidant effect of dietary supplementation with 500 or 1,000 mg/kg of a commercial rosemary extract vs. 200 mg/kg of alpha-tocopheryl acetate (alpha-TA) on the lipid oxidative stability of omega3-fatty acid (FA)-enriched eggs was compared. Lipid oxidation was measured in fresh eggs by the lipid hydroperoxide level and malonaldehyde content. Stability(More)
To assess the effect of supplying linseed oil (LO) in the diet on performance, fatty acid (FA) composition, and quality objective parameters of broiler meat, diets enriched with 0, 2, or 4% LO plus tallow (T) up to 8% added fat (T1, T2, and T3, respectively) were given to broiler chickens throughout a 38-d growth period. T3 birds were slaughtered at 24 or(More)
The effect of supplementation with different levels of all-rac-alpha-tocopheryl acetate and the inclusion of different dietary contents of PUFA on the deposition of alpha-tocopherol stereoisomers in liver and thigh of chickens was evaluated. Ninety-six 1-d-old Ross female broiler chickens were randomly distributed into eight experimental treatments (three(More)
We evaluated the effect of supplementing a basal diet containing 5% linseed oil with 0, 50, 100, and 200 mg/kg of alpha-tocopheryl acetate (alpha-TA) on alpha-tocopherol content, fatty acid composition, and lipid oxidation in fresh and spray-dried eggs during storage. Alpha-tocopherol transfer efficiency from feed to egg was also studied. The(More)
