The aim of the study was to determine an influence of diet additives in a form of protected palm oil, protected fish oil or unprotected fish oil with glycerol in Polish Holstein-Friesian cows on milk fatty acid composition, metabolism, milk yield and milk composition. Milk production, milk fat, and milk protein did not differ statistically between the groups. A significant increase (P<0.01) in ...

Trans isomers are formed from cis unsaturated fatty acids during biohydrogenation by rumen microorganisms and by commercial partial hydrogenation during the processing of vegetable and fish oils. Recent estimates indicate that consumers in Western countries may receive from 0.5-2.1% to 2.5% of total energy intake as trans fatty acids. In recent years special attention has been given to the pote...

The objectives of the current study were to 1) determine whether a fish-meal-supplemented diet fed to ewes during late gestation and early lactation would increase the proportion of docosahexaenoic acid (22:6n-3) in colostrum and milk and 2) examine the subsequent effect on the plasma fatty acid profile of nursing lambs. Eight gestating ewes (Rideau-Arcott; 97 +/- 5 kg of initial BW; 100 d of g...

Since little is known about the effect of selenium on the fatty acid profiles (FAP) of human breast milk, the purpose of this study was to measure the effect of habitual dietary selenium (Se) intake on this profile in plasma and breast milk. Subjects were lactating women from three locations in China where habitual selenium intakes are extremely low (Xichang), adequate (Beijing), or extremely h...

Effect of Bioactive Fatty Acids on Growth Performance Milk-Fed Holstein Dairy Calves Under Cold Stress

The objective of this research was to evaluate the physicochemical quality milk and cheese from goats-fed diets containing different concentrations flaxseed oil in replacement corn. Eight multiparous Saanen goats weighing 51.0 ± 8.0 kg 67.0 18.0 days lactation were used. According linseed inclusion diet, randomly distributed a latin square (4 x 4), according diet (0, 1, 2, 3%). Milk samples eac...

Recent studies have done much to clarify the biosynthetic mechanism of normal long chain fatty acid synthesis (l-$)., However, very little is known about the biogenesis of odd-m bered and branched long chain fatty acids. Odd-numbered fat@ acids have been identified as minor components of ruminant milk (5), human milk (6), human blood (7), human sebum (8), rat phospolipids (9), and the lipids of...

Shortenings are a mixture of one or more vegetable edible oil with partial hydrogenation in mixed with or without animal fat. In this study, three formulations of shortenings, with the best commercial and technological properties were prepared. Increasing consumption of shortenings at the human daily diet, with low adverse coronary effects in human daily diet, three formulations prepared using ...

This review details the specific needs of women for omega-3 fatty acids, including alpha linoleic acid (ALA) and the very long chain fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Omega-3 fatty acid (dietary or in capsules) ensures that a woman's adipose tissue contains a reserve of these fatty acids for the developing fetus and the breast-fed newborn infant. This ensur...
