Productive performance of goat kids fed of crude glycerin

This study was conducted to evaluate the productive performance of crossbred goats finished in feedlots fed diets containing increasing levels of crude glycerin (0, 4, 8 and 12%, DM basis). Twenty crossbred goat kids were used in a randomized complete block design with 4 treatments and 5 replications to determine average daily gain (ADG), dry matter intake (DMI) and nutrients (CP, NDF, EE) and ingestive behavior. For digestibility trial, four castrated male goats were used in a Latin Square Design to determine the DM and nutrients digestibility. Crude glycerin did not affect (P>0.05) the ADG, DMI and nutrients intake. Eating time increased linearly (P<0.05) with crude glycerin addition. Rumination time and dry matter and nutrients digestibility were unaffected by crude glycerin addition. However was a quadratic effect (P<0.05) to EE digestibility. It is recommended adding up to 12% crude glycerin to finishing kids, in situations of high price of corn, without changes in production parameters evaluated
