Supplementation of Dry Annual Range by Irrigated Pasture
Hull, J. L.; Raguse, C. A.; Guild, J. P.
Supplementation of a low protein, high-fiber, dry annual-range forage by irrigated pasture appears feasible. Data indicate that irrigated pasture can be used to increase the amount, or improve the quality, of beef production, and that it can compete economically with cottonseed meal as a supplemental protein source for cattle grazing dry annual-range forage./El estudio se llevó a cabo en la Estación Experimental de la Universidad de California ubicado en Browns Valley, California, E.U.A. Los tratamientos fueron; (1) pastizal seco solamente, (2) pastizal seco mas harinolina cada tercer día, (3) pastizal seco más ocho horas de pastoreo en un pastizal de riego tres veces por semana y (4) pastizal de riego solamente. El pastoreo se realizó con novillos y el pastizal de riego fué una mezcla de gramíneas y leguminosas. Se encontró que el uso de un pastizal de riego como suplemento dió más ganancias y animales de mejor calidad que el suplemento de harinolina, resultando además más económico.

Soil Moisture, Forage, and Beef Production Benefits from Gambel Oak Control in Southwestern Colorado
Marquiss, R. W.
Controlling Gambel oak and other brushy species with herbicides can produce benefits to the stockman. Increased forage and beef production are products of a good brush control practice. A high percentage of oak control is necessary to offset regrowth by sprouting. Soil moisture was significantly increased in the top five feet of soil during the summer months by controlling the oak. Forage production was doubled with a five-year period. Animal weight gains per acre nearly doubled as a result of brush control on Gambel oak rangeland.

Seasonal Changes in Herbage and Cattle Diets on Sandhill Grassland
Wallace, J. D.; Free, J. C.; Denham, A. H.
The chemical composition and dry matter digestibility of clipped plant species, total herbage, and actual and simulated cattle diets were studied on sandhill grassland in eastern Colorado during the growing season and after dormancy. Clipped plants declined in percent protein and digestibility and increased in other chemical components with advanced maturity. Marked differences in chemical composition were evident among species in early summer, but minimal by winter. Actual cattle diets and those simulated from hand clipped plants were similar in chemical and digestible dry matter composition during each sampling period. In early summer, cattle diets were considerably higher in quality than total herbage but this difference became progressively smaller later in the summer. During dormancy and after weathering chemical composition and dry matter digestibility of herbage and of the cattle diets were essentially the same.
