Extract

1. Africander and Mashona steers, fitted with rumen cannulae, were used to study levels of various nitrogenous fractions and of dry matter in the rumen of cattle grazing on natural subtropical herbage throughout the year. Some steers received various concentrate foods in addition to veldt grazing during winter. During the summer rainy season, four steers, two of each breed, were under trial, while in the winter drought period two extra steers of each breed were added to the experiment. The eight steers were divided into four groups for the winter, one group received a protein-rich concentrate, another group received a carbohydraterich concentrate, a third group was given a mixture of the two concentrates, while the fourth group received no additional food.
