Use of feed additives to improve feed efficiency and growth of feedlot cattle

The producers must observe feed efficiency (FE) and profitability in feedlot cattle under scenarios of high production costs associated with feeding. most efficient persistant way to change FE is using genetic tools. However, selection slow compared the use addititves, which work stabilize ruminal pH, induce beneficial changes rumen microbial population, increase energy protein metabolism. literature extensive about antibiotics, ionophores, non-ionophores increasing FE. Nowadays, "naturals" products as growth promoters has gained great relevance, promising results been reported. ). Therefore, this study aimed review additives beef
