| Abstract: | Grass silage containing 180 g crude protein and 660g digestible organic matter per kg DM was offered to forty-two dairy cows for 20 weeks in a self-feeding system. In addition, supplements of either mineralized barley (130 g crude protein per kg DM) or barley plus groundnut (180 g crude protein per kg DM) were offered. The mean daily milk yields were 18·5 and 19·4 kg per cow respectively. |
