Weaned Simmentaler steers were fed one of three basic rations viz. (l) silage ad lib.,(2) silage ad lib. + maize meal at l% of live mass and (3) 4 kg silage + maize meal ad lid. In addition each of these basic rations was supplemented by one of two concentrates which were composed as follows: A. 100 parts maize meal, 75 parts groudnut oil cake meal, 25 parts fishmeal and 10 parts urea at 1 kg per sheet per day, B. 96 parts lucerne meal and 4 parts urea at I,8 kg per steer per day. Each of the resulting six rations was fed to a group of ten steers. The highest DM intake occured where steers were fed maize meal at l% of live mass. This resulted in a significantly (P < 0,01) higher live mass gain as compared to the treatment receiving no grain.
