“…Burning increased EE of big and little bluestem, but little bluestem responded most (Table 3). Smith et al (1960), sampling burned and unburned bluestem pasture forage, found EE increased in three out of four trials due to burning; digestibility of EE was increased by burning in three of four trials. In contrast, Smith and Young (1959) reported a decrease in EE of little bluestem due to mid-spring burning.…”

The influence of range burning and nitrogen fertilization on the nutritive value of big and little bluestem in Kansas True Prairie were studied. Late spring burning decreased dry matter, crude fiber, cell wall constituents, cellulose, and lignin, and increased crude protein, ether extract, nitrogen free extract, and ash. Nitrogen fertilization decreased nitrogen free extract and increased crude fiber, lignin, and ash. Big bluestem was higher than little bluestem in nitrogen free extract, and lower in crude fiber, cell wall constituents, lignin, and cellulose. Range burning is a widely used management tool in the True Prairie region of Kansas because of improved steer performance (Smith and Owensby, 1972). Aldous (1934) reported burning increased range forage protein levels. Smith and Young (1959) reported higher crude protein and ash levels in little bluestem following burning. Smith et al. (1960) noted that burning increased apparent digestibility of dry matter and crude fiber. Although nitrogen fertilization of native True Prairie rangeland has not been widely used, recent attempts to increase carrying capacity have stimulated

“…This would indicate forage from burned nonfertilized pastures would be higher in digestibility; however, Woolfolk et al (1973) found no difference in digestibility, due to burning and nitrogen application. Smith et al (1960) reported burning improved digestibility of bluestem forage.…”

“…The impact of spring-season prescribed fire on forage quality has been evaluated. Forage obtained from pastures burned in the spring had increased carbohydrate availability and improved in vitro DM, crude fiber, and OM digestibilities when compared with forage obtained from nonburned pastures ( Smith et al, 1960 ; Allen et al 1976 ; Svejcar, 1989 ). Lack of differences in growth performance between the spring and summer prescribed-fire treatments in our experiment was interpreted to suggest that forage quality on pastures burned in spring or summer was similar.…”

Recent research demonstrated that mid- or late-summer prescribed fires can be employed to manage sericea lespedeza (Lespedeza cuneata) infestations in the Kansas Flint Hills. The effects of prescribed fire applied during the growing season (i.e., August to October) on grazing performance of yearling cattle have not been evaluated. Native pastures (n = 18; 22 ± 4.0 ha) were grouped by watershed and assigned randomly to 1 of 3 prescribed-fire treatments: spring (7 April ± 2.1 d), summer (21 August ± 5.7 d), or autumn (2 October ± 9.9 d). Yearling beef cattle were grazed from May to August at a targeted stocking density of 280 kg live-weight ˖ ha -1 following prescribed fire application. Forage biomass accumulations, soil cover, plant species composition, and root carbohydrate concentrations in four native plant species were evaluated. Total BW gains and ADG were greater (P = 0.01) for cattle that grazed the spring and summer prescribed-fire treatments compared with those that grazed the autumn prescribed-fire treatment. As a result, final BW were greater (P = 0.04) in the spring and summer treatments than the autumn treatment. Conversely, forage biomass accumulations did not differ (P = 0.91) between fire regimes. Proportions of bare soil were greater (P < 0.01) in the spring treatment compared with the summer and autumn treatments, whereas proportions of litter on the soil surface were greater (P < 0.01) in summer- and autumn-burned pastures compared with spring-burned pastures. Total basal cover of graminoids and forbs did not differ (P ≤ 0.15) between prescribed fire treatments. Likewise, total basal cover of C3 or C4 perennial grasses did not differ (P ≥ 0.23) between prescribed fire treatments. No treatment differences (P = 0.24) in root starch or root water-soluble carbohydrate concentrations in big bluestem (Andropogon gerardii), little bluestem (Schizachyrium scoparium), Indiangrass (Sorghastrum nutans), or purple prairieclover (Dalea purpurea) were detected. These data were interpreted to suggest that summer or autumn prescribed fire can be applied without reducing forage biomass accumulations, root carbohydrate concentrations in key native plant species, or considerably altering native plant populations compared with conventional spring-season prescribed fire; however, summer prescribed fire could be favored over spring or autumn prescribed fire to both maintain stocker cattle growth performance and to achieve control over sericea lespedeza.

En Calvillo, Aguascalientes, México, durante 2012 y 2013, se evaluó el efecto del fuego (tratamientos de quema Q y sin quema SQ) sobre la producción y calidad nutritiva del zacate rosado en tres etapas fenológicas: crecimiento C, madurez M, y latencia L. El fuego se aplicó en abril de 2012 a parcelas de 16 m2. Durante 2012 y 2013 la producción de forraje (base seca) fue diferente (p≤ 0.05) con 168.7, 393.7 g m2 y 53.9, 192.7 g m2 para los tratamientos Q y SQ respectivamente. La proteína cruda fue similar entre tratamientos (p≥ 0.05), pero diferente (p≤ 0.05) entre etapas C, M, L, con un total de 13.3, 5.2, 5.6% y 12.6, 4.6, 3.2% respectivamente. La digestibilidad de la materia seca (DISMS) resultó diferente (p≤ 0.05) entre tratamientos Q y SQ y entre las etapas de C, M, y L, con un total de 61.6, 46.0, 48.3% y 50.3, 42.5, 44% respectivamente. La fibra detergente neutro (FDN) resultó diferente (p≤ 0.05) entre las etapas C, M, y L, no así entre tratamientos Q y SQ con valores 67.1, 76.5, 78% y 66.4, 76.3, 79.6% respectivamente. La fibra detergente ácido (FDA) mostró diferencias (p≤ 0.05) entre etapas C, M, y L, más no entre tratamientos Q y SQ con un total de 35.8, 50.6, 57.4%, y 33.2, 54.6, 56.3% respectivamente. El fuego incrementó tanto la producción y calidad del forraje del zacate rosado y podría utilizarse como estrategia de manejo ecológica en áreas de pastoreo extensivo invadidas con zacate rosado.
