Extract

Forages, such as grass and red clover, are a rich source of n -3 polyunsaturated fatty acids, especially α-linolenic acid (C18:3n -3), and may be used as a method of improving the nutritional value of ruminant products. Silage is an important feed for cattle, therefore, a study was carried out to elucidate the effects of wilting and the use of additives on the fatty acid profile of the resultant silage.
