Milk or meat

  • J.A. Bines and I.C. Hart (a1)

Extract

During lactation, the cow partitions dietary energy between the production of milk and of body tissues. The balance between the two determines whether the cow is primarily a meat producer or a milk producer and the importance of this balance has been emphasized by Broster (1974). Differences between animals in partitioning ability are known to be inherited and are thought to be under endocrine control, but their effects on blood hormone and metabolite levels have not previously been studied. Knowledge and understanding of such differences may permit the early identification of the potentially high-yielding animal for selection purposes and may make possible the manipulation of energy partition towards a desired end.
