Abstract

We conditioned ewes and 10-week-old lambs to avoid calfmanna pellets by giving them capsules of lithium chloride following ingestion of calfmanna. We then exposed conditioned ewes and lambs to calfmanna in the presence of similar aged conspecifics that ate calfmanna. Intake of calfmanna by sheep with the conditioned food aversion increased (P<0.05) greatly when only calfmanna was available, but intake of the food increased little when an alternate food (alfalfa pellets) was available. Lambs were affected more (P<0.05) than ewes by social influences.
