One meat and bone meal and three meat meals, which - judged by their range in protein content - represented the common "types" available commercially, were analysed chemically and in animal trials. Besides the content of crude protein also amino acids, crude fat, crude ash and gross energy were analysed for. The digestibility of crude nutrients was determined by means of difference trials. The contents of crude nutrients showed only slight deviations as compared to the known mean values of respective types. In comparison, the ash content of the samples analysed here was slightly lower and the fat content slightly higher. For protein a digestibility of 83 % to 86 % was found and for the digestibility of the crude fat the values were 67 %, 82 % and 90 % as depending upon the particular type of product. The high digestibility in conjunction with the crude nutrient contents resulted in a high metabolisable energy content of all products.
