Extract

Recent studies have shown that when offered a choice of feeds with different concentrations of a particular nutrient (crude protein), sheep can select a diet that meets their current requirements (Kyriazakis and Oldham 1993). To further examine this diet selection behaviour a choice of foods differing in the concentration of S was offered to sheep that were either in a sulphur (S) adequate or a S depleted state. Study of S selection was considered to be the next logical step after protein because of its role in the synthesis of proteins by the rumen micro-organisms.
