A grazing trial was carried out in the Eastern Plains of Colombia to compare legume selection by transiently grazed oesophageal-fistulated steers and non-fistulated steers permanently grazing pastures. The 6 pasture types investigated were Arachis pintoi-Brachiaria humidicola mixtures which diffe...
