Fatty Acids Profile , and ∆9 -Desaturase Index of Milk from Barki Ewes Fed Diets Supplemented with Spirulina Platensis or Fish Oil

Comparison of ruminal lipid metabolism in dairy cows and goats fed diets supplemented with starch, plant oil, or fish oil.

Direct comparison of cow and goat performance and milk fatty acid responses to diets known to induce milk fat depression (MFD) in the bovine reveals relevant species-by-diet interactions in ruminal lipid metabolism. Thus, this study was conducted to infer potential mechanisms responsible for differences in the rumen microbial biohydrogenation (BH) due to diet and ruminant species. To meet this ...

Response of layers fed on diets dificient in protein and sulphur amino acids supplemented with lipid

Fatty acids profile of Spirulina platensis grown under different temperatures and nitrogen concentrations.

The influence of culture temperature and the concentration of sodium nitrate (NaNO3) on the gas-chromatographic profile of the fatty acids of the filamentous cyanobacterium Spirulina platensis was evaluated. We found that temperature was the most important factor and that the greatest amount of gamma-linolenic acid (GLA) was obtained at 30 degrees C, the fatty acid profile of the Spirulina cult...

Effect of Dietary Fish Oil Supplements on Levels of n-3 Polyunsaturated Fatty Acids, trans Acids and Conjugated Linoleic Acid in Ewe Milk

Three groups of ten lactating Sardinian ewes were used between 3 and 6 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 (B and C) were given the control ration supplemented with graded levels of ...

Butter composition and texture from cows with different milk fatty acid compositions fed fish oil or roasted soybeans.

Changing the milk fatty acid composition can improve the nutritional and physical properties of dairy products and their acceptability to consumers. A more healthful milk fatty acid composition can be achieved by altering the cow's diet, for example, by feeding supplemental fish oil (FO) or roasted soybeans (RSB), or by selecting cows with a more unsaturated milk fatty acid composition. We exam...
