Effects of adaptation to dietary fat on fatty acid composition of serum and serum lipids in miniature swine.
The influence of dietary fat on the serum fatty acid composition and distribution in different serum lipids was studied in 24 miniature swine (Sus scrofa) divided into 4 groups. Three groups were fed a low-fat chow with different kind of fats added (sunflower oil, olive oil and bovine lard) and the other group was fed a control diet with no fat added. The animals were fed the four diets for an experimental period of 12 weeks. Afterwards blood samples were taken to obtain serum, and the serum lipids were separated into the following fractions: phospholipids, triglycerides, and esterified cholesterol. The fatty acid composition of the serum and fractions was analyzed by gas chromatography. Under our experimental conditions, the fatty acid composition of the diets was reflected in serum, but not in all cases. In the triglyceride fraction the fatty acid composition was more evident. Our results show the interaction of the fatty acids in the different series and even within a single series, along with the endogenous synthesis processes.
