Cholesterol and vitamin E determination in broiler chickens fed cañóla oil

Abstract

This article describes the effect of canola oil on cholesterol and vitamin E (α and γ tocopherol) proportion in broiler chicken legs and breast. One hundred and twenty eight 1-day old broiler chickens were randomly assigned into 4 groups of 32 chicks each. Each group was divided into 4 subgroups of 8 chicks which received one of the four diets containing 15% oil with different percentages of canola oil (diet 1: 0%; 2: 5%; 3: 10%; and 4: 15%) for 31 days. Animals were sacrificed at day 45 to obtain samples. Cholesterol in legs and γ tocopherol in legs and also chicken breast did not show a clear trend according increased canola and decreased corn oil in the diets (despite of the higher γ tocopherol proportions found in corn oil). In conclusion vitamin E proportions found in canola oil did not influence vitamin E proportions in muscle tissue in broiler chickens.
