TROMBOGENIC, ATEROGENIC AND BLOOD PARAMETERS OF SWINE IN TERMINATION FEEDED WITH RACTOPAMINE AND DIFFERENT VEGETABLE OILS

The objective of this study was to evaluate the effect of the inclusion of vegetable oils (coconut and safflower oil) and ractopamine on feed intake, weight gain, feed efficiency, thrombogenic, atherogenic index and blood parameters (total cholesterol, HDL, LDL and triglycerides) of finishing pigs. Twenty-four castrated males with a mean weight of 78.00 ± 8.76 kg were distributed in a randomized block design with four treatments and six replicates. The diets used were T1 - Basal Ration (RB); T2-RB + 10 ppm ractopamine; T3 - RB + 4g of coconut oil and T4 - RB + 4g of safflower oil. Performance data, nutritional and blood parameters, and thrombogenic and atherogenic indexes of lard and loin sections were evaluated. No significant differences (p ≤ 0.05) were found for performance data and for nutritional parameters. Significant differences were found within the blood parameters for the variables of total and final total cholesterol, final LDL, final HDL and final VLDL. Thus, it was observed that coconut oil increased the total cholesterol and LDL levels, but in contrast, the use of safflower oil caused an increase in the HDL level of the animals.
