Uso de residuos de cosecha de arroz (oryza sativa), maiz (zea mays) y gandul (cajanus cajan) como complemento en la alimentación de bovinos de carne

This bibliographic review deals with the use of rice (Oryza sativa), corn (Zea mays) and pigeon pea (Cajanus Cajan) crop residues as a supplement in the feeding of beef cattle. Harvest residues are an attractive option to promote food security in cattle, which is why their use as production alternatives stands out, due to the high cost of commercial feed and which in turn allow to reduce production costs and the impact they cause to the environment. The conclusions determine that the contribution of corn and by-products as feed for cattle in the production units, decreases the purchase of commercial concentrates and feed costs; corn bran (AM) is made up of a mixture of corn bran, corn germ and part of the grain starch, which gives it a high-energy supplement with a fat level of not less than 4%; agricultural residues corn stubble and rice chaff presented high content of crude fiber and low level of crude protein; however, ammonification and solid state fermentation allowed to improve its nutritional value, with a marked increase in crude protein and true protein content; and, although the fibrous components remain high, their use in the preparation of rations for ruminant feeding could be encouraged and the harvest residues allow the cattle producer to be offered an alternative for the time when the summer affects the quantity and quality of available forage for the animals, in such a way that, at least, achieves weight maintenance and prevents losses.
