Description
Conjugated linoleic acid (CLA) is a mixture of positional and geometric isomers of linoleic acid (c-9, c-12 C18:2). Conjugated linoleic acid occurs naturally in foods, however the main dietary sources are dairy products and other foods derived from ruminants. Continuous interest in CLA is attributed to its potential health benefits such as anticarcinogenic, antiatherogenic, antidiabetic and antiadipogenic effects (Dhiman et al., 1999, Staszak et al., 2001). Typical consumption of CLA by humans is far lower than the dose that has been shown to be effective in reducing tumours in animal models (Dhiman et al., 1999), so it is very important to increase the CLA content of ruminants edible products. The CLA concentration can be positively influenced by animal diet. Grazing cows on pasture, feeding fresh cut pasture, addition of fish oil etc demonstrate positive effects on CLA content in milk (Bessa et al., 2000, Staszak et al., 2001). The objective of this research was to determine the CLA content of milk from cows fed diets containing different proportions of conserved forages.
