Effect of dietary fish oil supplements on livel of n-3 Polynsatutated Fatty Acid, trans Acids and Conjugated linoleic Acid in Ewe Milk
No full textThree groups of ten lactating Sardinian ewes were used between 3rd and 6th month of lactation to determine the effects of supplementing diets with n-3 fatty acids on milk production and milk fat composition. The control group (A) was fed on a mixture of Gramineae hay with a pelleted alfalfa and concentrate; the other groups (13 and C) were given the control ration supplemented with graded levels of fish oil. Milk content of nutritionally important fatty acids (n-3 polyunsaturated fatty acids, PUFA; trans acids and conjugated linoleic acid, CLA) was determined by gas chromatography. Unlike cow milk, milk of normally fed ewes contained detectable quantities of n-3 PUFA and higher amounts of CLA. The supplementation with fish oil resulted in an increased milk fat levels of n-3 PUFA, CLA and trans isomers. There was a positive correlation (R-2 = 0.964) between the trans and n-3 fatty acid content in ewe milk, and a close positive correlation (R-2 = 0.996) between CLA and trans monoenoic fatty acid contents. PUFA supplementation resulted in a slightly, but not statistically significative, decrease of milk fat percentage. On the contrary, dietary fish oil markedly affected milk production: ewes fed on the n-3 supplemented diet produced more milk than the ewes fed with the control diet
Composition and distribution of lipids in different parts of the seed from Vitis vinifera cv. Fortana
No full textLipid composition was determined in the separated seeds and pulp + peel of grape cv. Fortana. Tabulated results reveal important differences in composition. The seed oil contained 9.7% palmitic, 6.8% stearic, 20.5% oleic and 63.0% linoleic acid (vs. 11.7, 2.9, 19.0 and 34.0% in the pulp + peel); 1.5% cholesterol, 12.6% campesterol, 12.2% stigmasterol and 72.0% beta-sitosterol (vs. 0.6, 5.0, 3.8 and 88.1%, as well as 2.5% 7 stigmasterol, 11.4% erythrodiol and 2.6% uvaol, the last 2 not found in seed oil). The methylsterol fraction of the seed oil showed no known compounds, while pulp + seed contained only oleanoic and ursolic acid. Significant differences were also found in the alcohol (linear and terpene) and hydrocarbon fractions
