Implications of the use of blends of vegetable oils in diets for pigs in finishing pigs on blood dislipidemia, fatty acid profile and trombogenic and aterogenic indices
Enriched foods, unsaturated fatty acids, blood lipidemia, meat quality
The objective of this study was to evaluate different oil blends in feed for finishing pigs. Twenty - four castrated male pigs with initial weight of 72.0 ± 3.4 kg / PV were used in a randomized complete block design with four treatments and six replicates. The treatments consisted of: Soybean oil - 100%; and the combination of the different oils forming: Blend 1- (50% soybean oil, 25% flaxseed oil, 12.5% olive oil and 12.5% canola oil); Blend 2- (25% soybean oil, 50% flaxseed oil, 12.5% olive and 12.5% canola); and Blend 3- (25% soybean oil, 12.5% linseed oil, 12.5% olive oil and 50% canola oil). The blood parameters, fatty acid profile and thrombogenicity and atherogenicity indexes were evaluated in the following sections: loin, bacon, shank, palette, crown and belly. Blood parameters, saturated, unsaturated fatty acid profiles as well as thrombogenicity and atherogenicity rates were better with Blend2, Blend 3, respectively.
