The Effect on Milk Production of Feeding More than the Haecker, Eckles, and Savage Requirements

The results taken together indicate that feeding cows according to the Savage or Haecker standard, that is, so that they will just maintain uniform body weight, does not keep them at their maximum milk yield. The three experiments cited are in close agreement in showing that an above standard ration very materially increases production. The two short time experiments with cows well along in lactation give a 16 per cent increase in milk yield as the result of feeding 12 per cent more than the requirements; while the third experiment in which whole lactation period comparisons are used, showed from 14 per cent to 16 per cent increase in production as the result of feeding 17 per cent more than the requirements.
