Climatic Limit to Homeothermy for Lambs
ABSTRACT Aliterature review has established that low temperature limits survival and growth of newborn lambs. Relationships between lamb weight and summit metabolism were obtained based on available data. Relationships of ambient temperatures, coat condition, and wind to the heat production of lambs were also determined. Combined relationships provide estimates of the lower climatic limit to homeothermy for lambs based on their weight. These estimates are useful for environmental modification selection and design practices.
