Effect of Preparation Method on the Glycemic Response to Ingestion of Beet Pulp in Thoroughbred Horses
Groff, L., J. Pagan, K. Hoekstra, S. Gardner, O. Rice, K. Roose and R. Geor. 2001. Effect of preparation method on the glycemic response to ingestion of beet pulp in Thoroughbred horses. In: Proc. 16th Equine Nutr. and Physiol. Soc. Symp. pp. 125-126.
Summary
Previous studies in our laboratory demonstrated a marked glycemic response when horses were fed a fiber mix consisting of equal parts rice bran, soy hulls, wheat bran, and soaked beet pulp (Pagan et al. 1999). We speculated that, in part, the beet pulp portion of this fiber mix was responsible for the increase in plasma glucose concentrations after meal ingestion. We further hypothesized that the magnitude of the glycemic response to beet pulp would depend on how the beet pulp was prepared. Therefore, the objective of this study was to determine how different preparations of shredded beet pulp (beet pulp shreds, American Crystal Sugar Co.) affect glycemic response in Thoroughbred horses.
