Abstract

Feeding régimes and feed analyses are reported for 55 dairy farms in Aberdeenshire during the winter of 1969–70. An assessment of the rations suggests that the most serious nutrient deficiency was in the energy supply to high‐yielding cows. Phosphorus intakes were also low, particularly of low‐yielding cows. The incidence of other nutrient deficiencies is discussed. On many farms proprietary mineral supplements, used at the recommended rates, were inadequate for correction of apparent mineral deficiencies.
