Conteúdo: | In a previous comparison of oil meals as protein supplements for sheep (Briggs et al., 1946) soybean meal proved to be superior to cottonseed meal in nitrogen digestibility but not in biological value of nitrogen. Peanut meal which was equal to soybean meal in digestibility of nitrogen was inferior in terms of biological value. Earlier studies by Miller et al. 1937 had showed that lambs utilize with equal efficiency the nitrogen in rations containing soybean meal, linseed meal and corn gluten meal. Their results, together with the results obtained by Johnson et al. 1942 with lambs fed urea rations, afford the best evidence of the similarity in biological value of widely different protein supplements for ruminants. Nevertheless, Lofgreen et al. 1947 have reported that, for sheep, egg protein is superior to linseed meal in biological value, and similarly Chalmers and Synge (1954) have reported herring meal to be superior to casein. The reason for such differences is not entirely clear. Because of new developments in processing oil meals, attended by change in nutritive value (Miller and Morrison, 1944; Eagle et al., 1956), and because of the wide use of these products in ruminant rations, it seemed worth while to compare certain ones on the basis of growth promoting properties, digestibility and biological value of nitrogen. Experimental: The oil meal supplements selected for comparison were two samples of cottonseed meal,2 one of low and one of high nitrogen solubility, a sesame oil meal, and a mixture of sesame and solvent-processed soybean
