Two experiments were conducted with 26 Holstein and Brown Swiss cows, the first (E-1) during the dry season (February to April) and the second (E-2) during the rainy season (July to September). Treatment L, which involved 3 hours daily of grazing in protein banks of leucaena and associated grasses, was compared with a control (T) of grazing in grass herbage only. The paddocks of grass alone received no fertilizer. Vegetation was scarce during the dry season, but abundant during the rainy season. Individual supplementation with concentrate feed (16% crude protein, CP) was according to production, but the maximum daily allowance was fixed at 7 kg. The experimental design was a cross-over (single reversal of treatments) with 21-day comparison ...
