Harvesting methods of Erythrina leaves were studied from May 27, 1993 to November 16, 1995 at Khon Kaen Animal Nutrition Research Center. Establishment period was one year. Erythrina leaves harvested during one and half year period from the May 27,1994 to November 16, 1995, were used to compare with treatments. The treatments were two harvesting methods, cutting and leaf stripping, and three harvesting frequencies; 90, 135 and 180 day intervals. Cutting and leaf stripping had no effect on leaf dry matter yield. Dry matter yield harvested every 180 days was 4.65 kg/plant, significantly higher than the 3.80 and 3.87 kg/plant, harvested from the 90 and 135 day intervals, rspectively (P0.05). In contrast, Erythrina leaves harvested every 90 and 135 days had a degradability percentage significantly higher than that harvested at 180 day interval (P0.01). the degradability percentages were 64.65, 63.37 and 58.59 percent of dry matter, respectively.
