A.  aRyegrass pasture for supplementing southern pine native range.h[electronic resource]  c1987  aCattle grazing southern pine range are managed primarily as cow-calf operations. Brood cows, predominantly Brahman crossbreeds, generally graze yearlong. Several studies have shown deficiencies in native forages meeting the nutrient requirements of beef cattle, especially during winter. Protein and energy deficiencies for breeding cattle seriously reduce calf crops and weaning weights. Several feeding alternatives such as cottonseed cake and hay, liquid supplements, or supplemental winter pasture exist for improving animal production and economics. This paper reports resuits from grazing supplemental ryegrass pastures in conjunction with native bluestem range. A study was conducted on effectiveness of a small acreage of supplemental ryegrass pasture in meeting winter nutritional needs of cattle grazing native southern pine range yearlong. We also compared the economics of strip and open grazing of supplemental ryegrass pastures.  aFloresta  aGado  aPastagem  aPine1 aROLLINS, D. A.  tRangelandsgv. 9, n. 1, p. 19-20, 1987.
