A concentrate made up 40% of the ration offred. The animals (8) were grouped to the two treatments . accordin to their age and body weight; the mean differences were tested by the t test.The digestibility of nutrients was estimed by use of chroium oxide, and the samples were analyses according to the Weende and Van Soest procedures.
