The productivity of intensively managed pastures of Congo, Star, and Pangola grasses was compared in the mountain region of Puerto Rico under conditions typical of vast areas in the humid topics. Stargrass produced higher weight gains (1,274 lb/acre (1,427 kg/ha) yearly) and had a higher carrying capacity (2.91/600-lb steers/acre or 7.27/273-kg steers/ha) than did Congo or Pangola grasses, which were similar in both these respects. Apparent in vitro digestibility (66%) and protein content (21.1%) of Stargrass was higher and lignin content (4.6%), lower than that of Congo or Pangola.
