Autor: S.I. Bechdel, R.E. Ward, N. B. Guerrant
Publikováno v: Journal of Dairy Science. 23:115-124
Summary The data obtained in this series of studies show that the minimum carotene requirement of growing calves is eleven micrograms per day per pound body weight. This level of carotene intake was sufficient to maintain growth and to prevent the us

Studies in the Normal Depositions of Minerals in the Bones of Dairy Calves
Autor: S.I. Bechdel, J.H. Kruger
Publikováno v: Journal of Dairy Science. 11:24-34
Summary The composition of the frontal, ribs, femurs, and humeri of seven normal male Holstein calves are presented. These calves were 60, 90, 120, 150, and three of 180 days of age. The analyses indicate that the ribs, femurs, and humeri are suitabl

Utilization and Excretion of Ascorbic Acid by the Dairy Cow
Autor: N. B. Guerrant, C. A. Knight, S.I. Bechdel, R.A. Dutcher
Publikováno v: Journal of Dairy Science. 24:567-577
Summary 1.Special equipment was employed which permitted the complete collection from dairy cows of 24-hour samples of urine free from any fecal contamination. It was found impractical, if not impossible, to preserve all the ascorbic acid in such uri

Autor: S.I. Bechdel, R.A. Dutcher, M.G. Vavich, N. B. Guerrant
Publikováno v: Journal of Dairy Science. 28:759-770
Summary A Holstein cow was maintained in normal physical condition for a period of 15 months on a ration containing very little ascorbic acid. During this period a normal male calf was born. Blood plasma ascorbic acid values ranged from 0.28 to 0.59m

Publikováno v: Journal of Dairy Science. 22:321-328
Summary A vitaminosis A was produced in growing calves through the use of poor quality bleached and aged timothy hays fed in connection with a grain mixture. Fresh carrots and alfalfa hay (dehydrated) of good quality were quite effective in correctin
