Abstract

Feed blocks are solid mixtures composed mainly of agro-industrial by-products and crop residues (see illustrations), associated with other products such as urea, mineral and vitamin supplements and other preservatives or binders. They are used to replace part of forages and concentrate feeds but also as a nutritional supplement for ruminants during periods of feed shortage or feed deficit. When properly mixed and dried, the feed blocks may be stored for long periods (2 to 3 years). They are consumed slowly by animals and have no detrimental effects on the digestion and the animal health and help to stabilize production even in dry years.
