High-level Grain Feeding for Dairy Cows

Our interest in the more liberal grain feeding of good cows was prompted by the field observations of Donald tIlllman of the MSU Dairy Department, noting that many inherently high milk producing cows were underfed on energy. This is the case, despite the fact that the revolution in corn production, due to the use of hybrid corn and better fertilizer and cultural practices, has made possible cheaper sources of nutrients than roughages on many farms.
