Crude glycerin in the supplementation of crossbred heifers in tropical pastures
Crude glycerin (CG) is a biodiesel byproduct that has been tested as an alternative feed additive for use in beef production. After being absorbed, it is used in the liver to produce glucose, an important precursor of intramuscular fat in ruminants. This study aimed to evaluate the effect of CG (439...

Thirty-six heifers with an initial BW of 301.5 ± 23.02 kg were used.
