Abstract
    In Norway considerable quantities of fish meal, especially herring meal, have been produced over many years. As this fish meal has been sold at prices competitive with those of oil seed meals, fish meal as a feed for ruminants has for a long time aroused a great interest. On account of the good results attained by using herring meal to supplement poor rations, the farmers now have great confidence in herring meal. Hence they often request that feed mixtures for ruminants should contain herring meal. In Norwegian experiments, with about 450 dairy cows, varieties of fish meal have been compared with oil seed meals. By the use of poor rations, made up of low-quality roughage, a response to herring meal has been established in the milk yield. In more recent experiments in which better-quality forages and balanced rations have been supplied, it was not possible to confirm that herring meal raises the milk yield. In two of the experiments, however, the herring meal raised the content of milk protein significantly. In corresponding experiments with young cattle, herring meal gave higher live weight gains than did oil seed meal. In the feeding of sheep and goats, fish meal has proved to be of great value as a supplement to roughage rations. Finally, fish meal, and especially better-quality herringmeal, seems to be acceptable to ruminants, and may replace oil seed meal according to their contents of digestible protein. When poor-quality rations are supplemented, the high content of minerals and vitamin D (herring meal) of the fish meal may be a valuable asset.
