Lambs turned into desert valley alfalfa fields during winter will make profitable gains if they are moved to another pasture after 10 days of grazing, when the alfalfa is nearly devoid of leaves.

Appreciation is expressed to Broadbent Livestock Co., El Centro, California, for the use of lambs and fencing material, and to Pioneer Hybrid California Crop Improvement for financial assistance. Thanks are given to Ms. Carol Adams, UC Cooperative Extension Biometrician, for assistance with data analyses.
