Comparison of the ash of the new-born calf with that of the full-grown steer

These analyses of the mineral constituents of bovine feti are a continuation of the work done by Mr. E. E. Vanatta and Mr. A. G. Hogan on a special investigation by the Agricultural College or the University of Missouri. Messrs. Vanatta and Hogan gave the results of investigations on the composition of the ash of dogs, birds, human, horse, cows, and other animals. Of new born animals, work has been done on the human fetus, guinea-pigs, rabbits, etc. All this work, however, can have very little particular bearing upon the composition of the ash of the new born calf, as it has been demonstrated that not only species but also breed effects the composition of the entire animal including the mineral constituents. In this analysis, two calves were used. The first, a pure bred Hereford, was carried until two weeks over due and strangled at birth. The weight of the calf was 88 pounds, 4 ounces. The second foetus upon which an analysis was run was a pure bred Jersey. The cow was 5 years, 3 months old, and was slaughtered in January 1914. The foetus was 7 months and 24 days old, weighing 30 pounds.
