Dietary Chemical Composition of Cattle and Sheep Grazing in Common on a Dry Annual Range

Significant differences among animals were found in chemical composition of dietary samples collected with esophageal fistulated cattle and sheep grazing in common on a dry annual range. Diets from sheep and in early summer were higher quality than from cattle or in late summer. Six or fewer animals would suffice to sample most dietary constituents within 10% of the mean with 95% confidence.
