Extract

Short-term grazing trials with daily blood sampling were carried out on Welsh mountain ewes in early lactation.

1. A small decrease in serum magnesium levels and a very marked decrease in serum inorganic phosphorus levels, were observed in two groups of four ewes, when one group was transferred from an old pasture to a fertilized (high nitrogen and potash) fresh spring ley, and the others to a similar fresh ley but untreated. There was little effect from the fertilizer treatment on the magnesium, calcium, potassium, sodium or phosphorus content of the herbage.
