In this investigation, silage made from cattle waste being ensiled with maize residues (ECW), was evaluated with respect to ensiling characteristics and feeding value. Cattle waste was obtained from cows that were finished on a high-concentrate (80%) diet. It was collected together with maize residues which served as bedding material for animals housed on a concrete floor. The mixture consisted of approximately 70 parts of manure and 30 parts of maize residues. Effective preservation was indicated by the following measurements after an ensiling period of 2 months: pH 4,24; lactic acid content 7,8 g/100 g dry matter (DM); total volatile fatty acid content 4,6 g/100 g DM and butyric acid content 0,16 g/100g DM. In a growth study, steers fed on ECW showed a daily mass gain of 0,20 kg/day in comparison to 0,46 kg/day by steers fed on maize residues (P<0,01). Organic matter intake for both treatments was the same. Apparent digestibility of organic matter however was found to be 61,7% for steers fed on ECW and 57,2% for steers fed on maize residues (P<0,01). When ECW was fed as the roughage component (30%) of a high-concentrate diet, however, it compared well with Eragrostis· curvula hay as roughage component. Steers fed on a high-concentrate diet containing ECW showed a feed conversion of 6,50 kg DM intake/kg gain in comparison with a feed conversion of 7,39 for steers fed on a high-concentrate diet containing Eragrostis curvula hay as roughage component. Also, carcases of steers fed on the ECW-containing high concentrate ration tended to be of a better quality and scored 8,9 points out of 13 in comparison with steers fed on the Eragrostis curvula-containing high concentrate ration which scored 7,5 points (not significant).
