Abstract
The first part of this review papers presents the history of tall fescue endophyte toxicosis, which used to be a real constraint on grazing beef industry in southern US. The second part reviews some up-dated scientific publications, dealing with vitamins, fats and fatty acids in grass, grass products as well as in animal products produced on these feedstuffs. The papers cited prove that inclusion of grass or conserved (hay, silage) grass in the diets for cattles (beef and dairy) pigs or poultry (broiler chicken and leying han):
- reduces the fat content of the body
- improves some vitamin contents of animal products (milk, butter, meat, eggs)
- improves the unsaturated fatty acid contents of the same animal products.
The consumption of these high quality animal products consequently may contribute to better human health status of consumers.
