Urea Molasses Multinutrient Blocks
  Urea molasses multinutrient blocks As the name suggests, these are lick blocks containing urea, molasses, vitamins, minerals and other multinutrients. The feeding of the blocks is a convenient and inexpensive method of providing a range of nutrients required by both the rumen microbes and the animal, which may be deficient in the diet. The main justification for using the blocks depends on their convenience for packaging, storage, transport and ease of feeding. The ingredients are designed to provide a wide rage of nutrients to cover all potential deficiencies. In the wet tropical regions minerals are often deficient in cut and carry grass or crop residue feeding systems. Grasses from road sides or wastelands are particularly low in minerals as generally, no fertilizer is used and the grasses have often been cut for decades for ruminant production, thus depleting the reserves of both soils and plants.
