Conteúdo: 	A model was developed in an attempt to predict the selection ratio of little bluestem (Schizachyrium scoparium) and brownseed paspalum (paspalum plicatulum) in a simulated short-duration grazing system stocked at four different levels. The research was carried out over a two year period (1981 and 1982) in a Schizachyrium-Paspalum grassland of the Post Oak Savannah located at the Texas A&M Native Plant and Animal Conservancy near College Station. Linear and multiple regression analyses were used to determine the variables herbage allowance (total, little bluestem and brownseed paspalum), extended tiller height, live:dead ratio of tillers, temperature, rainfall and stocking rate influencing selection ratio of little bluesten and brownseed paspalum. Total herbage allowance was not restrictive for the potential intake during 1981. The increased grazing pressure for all stocking rates during 1982, coupled with low precipitation during the late growing season, affected herbage allowance only in the two stocking, rates during the fall and early winter. Herbage allowances of little bluestem and brownseed paspalum were the most important variables for predicting selection ratios of both species. Increased herbage allowance of little bluestem favored the preference of brownseed paspalum. This interrelationship was more noticeable in 1981 when grazing pressure was less than 1982. Mean tiller height and mean live:ded ratios of both species also accounted for variability in selection ratios for these key species. Total...
