ABSTRACT
Milk components, with respect to the potential for improving health and the prevention of health problems, are intermediate products of the biohydrogenation of poly-unsaturated fatty acids in the rumen of cattle. Dairy products are a major source of conjugated linoleic acids (CLA) in the human diet. It has been demonstrated that CLA can suppress carcinogenesis, modulate the immune system, and can have an anti-obesity effect, while reducing atherogenesis and diabetes. Controlled intervention studies showed that trans fatty acids have a significant adverse effect on the LDL cholesterol level. The aim must therefore be to have a high content of poly-unsaturated fatty acids and CLA in milk, while concurrently having a low content of trans-9 and trans-10 C18:1 fatty acids. The high correlation between CLA and the sum of all trans fatty acids of r = 0.88 in milk fat demonstrates that this goal is not easy to achieve. New feeding strategies for lactating ruminants in which an independent regulation of the different C18.1 isomers is considered as pasture feeding, concentrate to roughage management, use of protected plant oils and use of milk fat low-sensitive cows have to be developed.
