An experiment was conducted to investigate possible differences in DM intake and diet selection between groups of calves and cows grazed alone (YCA and ACA) or with lambs (YC+S and AC+S) in a ratio 1:1 (based on W3/4) on a temperate ryegrass/white clover pasture for 11 days. Treatments were compared at similar rates of daily disappearance of pasture mass (PM) (RDPM). Digestible DM intake (DDMI) was measured by faecal output/diet DM digestibility (DMD) method. Faecal output was estimated from chromic oxide dilution. Marker recovery rate was estimated from total faecal collection obtained in an indoors trial using similar animals. Samples of ingesta for botanical composition and in vitro diet DMD analysis were retrieved from oesophageally fistulated cattle. Herbage was sampled from each treatment every 2 days to determine botanical composition and DM digestibility of the weard. Pasture botanical composition changed differently among treatment with grazing. Data suggest an influence of animal size (cattle) on pasture changing composition, with calves presenting a greater change for grass and dead matter than cows. However, treatment did not show a clear effect on mean pasture DMD. The diet of calves showed a slightly greater change in DMD during the grazing period than cows (-17, -22, -14 and -21 DMD units % from an initial diet DMD of 70, 76, 72 and 75%ùfor YCA, YC+S, ACA and AC+S respectively) which is consistent with the botanical composition change for these same treatments.
