Digestibility studies on pure samples of barley, oats and wheat, with and without admixtures of oats, wheat, barley, wild oats and weed seeds, were carried out using white rats. Apparent digestibility coefficients for dry matter, crude fibre, crude protein, and energy, together with metabolizable energy values were determined for each diet. The results indicated that the individual grains and their admixtures have characteristic digestibilities. The varying additions to barley or wheat of grains other than the main grain and/or of wild oats or weed seeds reduced the digestibility of dry matter and digestible energy and likewise metabolizable energy of the admixtures. The opposite effect was obtained for the oats admixtures. A highly negative correlation between digestible dry matter and percentage crude fibre was found for the barley, oats, and wheat diets; while a highly positive correlation was found between the digestible energy and dry matter of these diets.
