Abstract

A metabolism study was conducted to evaluate the impact of increasing levels of glucogenic precursors on diet digestibility and acetate clearance. Four supplementation strategies containing 0, 30, 40, and 70 g of supplemental glucogenic potential were supplied to a basal diet of bromegrass hay. Addition of glucogenic potential in the form of rumen undegradable protein improved dry matter, organic matter, and acid detergent fiber digestibility efficiency of acetate utilization in growing lambs fed moderate- quality hay. However, no additive effect of supplementing propionate salts and rumen undegradable protein were observed in this study. Th is would suggest that rumen undegradable protein requirements must be met to observe effects from increasing levels of glucogenic potential.
