Range Improvement Following Chaining of South Texas Mixed BrushDouble chaining followed by raking and stacking heavy stands of south Texas mixed brush was more effective than double chaining alone or chaining one way, based on comparative degree of brush control, range forage production, and forage consumption by livestock. In a brush stand composed primarily of honey mesquite, spiny hackberry, and lime pricklyash, double chaining followed by raking and stacking reduced woody plant densities by 88%, increased oven-dry forage production by over 1,600 kg/ha, and increased forage consumption by 950 kg/ha as compared to untreated areas a year after treatment. Double chaining alone was less effective than double chaining, raking, and stacking in promoting forage production and consumption and did not improve management efficiency. Chaining one way was not considered an effective practice.
Summer Diets of Steers on a Deep Hardland Range Site of the Texas High PlainsBotanical and chemical compositions of the summer diets of esophageal-fistulated steers were determined on a deep hardland shortgrass range site of the Texas High Plains. Consumption of belvedere summercypress was highest in June, but decreased to September; whereas, consumption of blue grama, buffalograss, and sand dropseed increased during this period. Belvedere summercypress was eaten in considerable quantities until it approached dormancy. Dietary crude protein and calcium percentages were highest in June, but declined to September. Daily forage consumption averaged 10.9 kg during June and July. A forage utilization of 17.4% was obtained during the summer grazing period and the steers gained an average of .45 kg/day.
Survival of Cool-Season Species under Texas-Pecos ConditionsFour cool-season species were grown for 1 year under controlled conditions simulating a dry, a typical, and a wet fall planting season in far west Texas. Crested wheatgrass and Russian wildrye had higher survival percentages than sideoats grama at the end of the study. Both species appear capable of reducing the cool-season forage shortage in the Trans-Pecos region of Texas. Neither wintergreen hardinggrass nor burnet appear adapted to the Trans-Pecos. Seedling morphology did not affect plant survival.
