Abstract
ABSTRACT The objective of this study was to evaluate the effects of adding crude glycerin with food additives (sodium monensin or essential oils) to the diets of beef cattle on feed intake, ruminal parameters, in vitro digestibility, and production of greenhouse gases. Five ruminally cannulated Nellore steers were randomly assigned in a 5×5 Latin square design. The treatments were: control, without crude glycerin and additives; with essential oils and without crude glycerin; with sodium monensin and without crude glycerin; with [...]

Summary
Glycerin is the major byproduct of the conversion of vegetable oils and fats into biodiesel. The use of crude glycerin as an alternative energy source in ruminant diets has shown promising results (Ezequiel et al, 2015; Favaro et al, 2016; Almeida et al, 2017), mainly as a replacement for corn grain. In addition to the opportunity of byproduct utilization, the use of growth promoters (ionophores) in ruminant diets has been used to maximize energy efficiency and utilization of dietary nutrients with even more favorable economic results. Sodium monensin is an ionophore antibiotic widely used and well documented in ruminant feeding mainly to minimize metabolic disorders and improve energy efficiency of diets (Azzaz et al, 2015). 1831/2003), animal nutritionists are researching new alternatives to ionophores, such as essential oils To meet the constraints imposed by some consumer markets (e.g., the banning of sodium monensin as a growth promoter by the European Union, Regulation EC no. 1831/2003), animal nutritionists are researching new alternatives to ionophores, such as essential oils
