Variation between Breeds in Feed Cost of Milk Production

Lynn Copeland

Kentucky Agricultural Experiment Station, University of Kentucky, Lexington, Kentucky

ABSTRACT

  1. Jersey cows produced butterfat at a lower feed cost per pound than Holsteins.
  2. Holstein cows produced milk at a lower feed cost per 100 pounds than Jerseys.
  3. On the basis of energy as expressed in 4 per cent F.C.M., there appeared to be no significant difference between breeds in cost of production.
  4. Purebred herds apparently produced 4 per cent F.C.M. at-a lower feed cost than did grade herds.
