Description
Summary:The Calan Feeding Control System (Am. Calan, Inc., Northwood, N.H.) is used to obtain data on forage selection by livestock. We modified the dimensions of the system and tested it with 2 adult male desert bighorn sheep (Ovis canadensis mexicana); modifications were adequate for bighorn sheep. The animals required 7 days to adjust to the feeding frame and 9 days to learn how to use the controlled-access feeding system. Consumption by bighorn sheep of a daily ration decreased about 50% during the learning phase but returned to maintenance levels within 14 days. Controlled-access feeding serves as an alternative to traditional techniques for quantifying diets.
