FORAGE HERBS IN GRASS MIXTURES FOR DAIRY PRODUCTION

The forage herbs chicory (Cichorium intybus) and plantain (Plantago lanceolata) have become regular components of south-eastern seaboard dairy pastures. They are mostly planted in a mixture with grasses and often clover species are added as a minor component. How they do and what benefits they bring to the pasture mix and the cow have not been well researched in these areas. This was then the purpose of the trials cited below. 

BENEFITS OF CLA ADDITION TO YOGURT

Conjugated linoleic acid (CLA) has the ability to inhibit growth in a number of human cancer cell lines. It is also immune-modulating and growth-promoting and was shown to decrease fat mass without significantly affecting body weight. In terms of prevention of heart disease, CLA depressed total cholesterol and lowered the ratio of low-density lipoprotein (LDL) to high-density lipoprotein (HDL).
