Notes:
Two paddocks each received a total of 412 kg N/ha (371 lb/ac) between April and July in four equal applications. The paddocks were grazed four times for four days by two groups of 5 Friesian cows starting 14 and 21 days after each N applica tion.The nitrate-N content of the herbage DM reached a peak of 0·76 % in the third grazing 14 days after N application. There was a significant (P 〈 0·001) correlation (r =0·67) between water soluble carbohydrates and nitrate-N in the herbage DM.No marked changes occurred in eitber the methaemoglobin or packed cell volume of the blood samples from either group.No detrimental effects on animal health or production were recorded during the experiment.
