Haulms from 10 different genotypes of groundnut were tested with growing male sheep for digestibility, intake, nitrogen retention and live weight gains. Very high daily intake levels of > 4% of sheep bodyweight were observed in all haulms. Nitrogen retention (range: 6.7 to 11.4 g/d) and live weig...
