The influence of stocking rates on animal’s performance and forage selectivity through co-grazing of sheep and goats within pastures that contain various species of grasses and forbs was examined at the E (Kika) de la Garza American Institute for Goat Research of Langston University, Langston, Oklahoma (35˚ 94’ N; 97˚ 25’ W). Nine pastures were randomly assigned to three different stocking rates (low-4, moderate-6, and high-8). Pastures were divided into four paddocks that were grazed over two, two week periods with 6 weeks of regrowth between grazing periods. Pre- and post-grazing forage production and cover were measured. Fecal grab samples were collected to determine animal preferential diet selectivity.
