Predator Control in Relation to Livestock Losses in Central Texas

Abstract
Records of the 1971-1976 federal-state Animal Damage Control (ADC) program in central Texas reflected 0.27% annual domestic sheep and goat losses to predators, despite intensive control efforts. Sheep and goat numbers decreased but their value, cattle numbers and cattle values increased. Losses to coyotes and bobcats were proportionately greatest in brushy, uneven terrain on the periphery of the Edwards Plateau. In 1975, cooperative ADC predator control efforts protected 438,649 (40%) of the sheep and goats on 8912 km2 (3441 mi2), or 15.5% of the total land area in 21 counties studied. Heaviest losses to predators occurred from Oct.-May when small lambs were present; control efforts were most successful during winters. Losses to predators were lowest when annual precipitation was highest; high losses coincided with dry years, which were probably the periods of lowest wild prey abundance.
