Davis, H.P. and Hathaway, I.L. (1959) Growth measurements of Holstein, Ayrshire, Guernsey and Jersey males (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 189)
This study was based on monthly observations of all Holstein, Ayrshire, Guernsey and Jersey males born in the University of Nebraska dairy herd between 1922 and 1942. There were varying numbers of animals for the different months of age for the several breeds. Measurements of weight, slope of the rump, thickness of skin, and 13 linear measurements were taken monthly, from birth to disposal of the animals. The linear measurements were of heights at withers, hooks and rump; of lengths-diagonal (shoulder point to pinbone), body and rump; of widths at chest, hooks and pinbones; of depths at chest and barrel; and of girths at chest and barrel.
