Untreated urea and urea treated with 1.5 % formaldehyde were compared as nitrogen sources for young growing bulls. The experiment was performed with 12 individually fed animals, eight of which were Friesians and four Finnish Ayrshires, and the average age of the animals at the beginning of the experiment was about 3.5 months. After a standardization period of two weeks, the animals were divided into two groups with similar distributions by daily gain, feed utilization, liveweight and age. During the following transition period of one week the feeding of the animals was changed to the experimental diets of the 24-week test period. The feeding was based on NaOH-treated barley straw and a mixture of barley, oats and molassed beet pulp, and pla...
