Two feeding trials were conducted on local goats to investigate the effect of urea on both quantity and quality of milk. In the first trial, two groups of lactating goats were fed similar commercial feed plus 1% urea in the feed of one group. In the second trial, same number of pregnant goats were used to investigate urea feeding on colostrum and milk quality. Urea addition in experiment 1 had no significant effect on total milk production, total milk protein, casein, but significantly (P<.05) increased total solids and milk fat. In the second experiment, urea had similar effects as in the first experiment. Colostrum composition was not affected by urea treatment.
