ENRICHMENT OF PORK WITH BLENDS OF OILS: STUDY OF BLOOD PARAMETERS, PROFILE OF FATTY ACIDS AND TROMBOGENIC AND ATEROGENIC INDEX
Enriched foods, unsaturated fatty acids, blood lipidemia, meat quality
The objective of this study was to evaluate the effects of the inclusion of different vegetable oil blends in diets for pigs in relation to the study of blood parameters, fatty acid profile and thrombogenic and atherogenic indexes, aiming at improvements in meat quality. 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 went with the Blend 3.
