Production Performance and Carcass Traits of Fattening Goats Fed Crude Glycerin in Total Mixed Ration

Abstract

The objective of this study was to examine the performance and carcass traits of goats fed with diets with different levels of crude glycerin (CG). A total of 24 male goats (17.4 + 1.8 kg initial BW) were randomly assigned to receive diets containing 4 CG levels (0, 5, 10, and 20% of TMR DM). The diets were fed for ad libitum intake. Goats were slaughtered after 91 days of study. Hot carcass weight and carcass traits were recorded. Based on this experiment, CG levels did not affect final BW, DMI, ADG, and feed efficiency (G:F). Similarly, carcass characteristics were unaffected by dietary treatments (P>0.05). We concluded that CG can be used as substitution for corn grain up to the level of approximately 20% of dry matter in the diets of fattening goats.
