“…The overall rate of increase was 7.2 and 12.2% for NDF and ADF, respectively. Volesky et al (2008) reported a 9% rate of increase for NDF between December and January and Meyer et al (2009) found values for both fiber concentrations similar to those presented here.…”

e role of winter pasture management for beef production systems requires clari cation. We designed four pasture management systems to sustain a 0.5 kg average daily gain (ADG) of spring-born steers during fall and winter. e experiment was conducted at West Virginia University, Reedsville Experimental Farm. Treatments replicated three times on 0.81 ha grazing units included: (i) naturalized grazingland with haylage (NGH), (ii) orchardgrass (Dactylis glomerata L.) cultivated pastureland, animals moved to drylot with hay (OCD), (iii) orchardgrass cultivated pastureland with haylage (OCH), and (iv) tall fescue (Lolium arundinaceum, Schreb., Darbysh.) cultivated pastureland with haylage (TCH). Grasslands were stockpiled from August and N (84 kg ha -1 ) was applied to all except NGH. Grazing began in November and ended in January with a stocking density of 4.9 steers ha -1 hay or haylage were fed until April. Pelleted soybean (Glycine max L.) hulls (PSH) were fed when ADG fell below 0.5 kg. Herbage disappearance was highest in TCH (1521 kg ha -1 ). Herbage accumulation of TCH was reduced more by dry weather during stockpiling. Di erences in nutritive value between grasslands were small, as OCH and OCD had greater crude protein (CP) whereas NGH had lower CP. No di erences in ADG were found between treatments; however, in 2006-2007 and 2008-2009 with early and persistent snow cover, supplementation was required, being signi cant in 2006-2007. Yearling steers can be maintained during winter with a combination of stockpiled and conserved forages fed to achieve gains of 0.5 kg ha -1 d -1 .

“…Prigge et al [24] and Baker et al [25] found similar forage production for orchardgrass during autumn at the WVU Reedsville Experiment Farm. Tall fescue mass determined in our experiment was less than that reported in North Carolina [26], but similar to the amounts obtained at Morgantown, West Virginia [6,7], Wooster, Ohio [27], and Columbia, Missouri [28]. Volesky et al [4] observed that orchardgrass was more susceptible than tall fescue to effects of snow compression and as a result would present relatively less herbage available for grazing.…”

“…Volesky et al [4] reported for orchardgrass NDF concentrations between 562 and 629 g kg −1 , from December through January with slightly greater NDF for tall fescue during the same period. Meyer et al [28] reported NDF and ADF concentrations similar to those presented here. Cultivated grasslands during the winter of 2012-2013 had chemical composition that was comparable to high quality forage in spring (e.g., high CP and low fiber).…”

Winter grazing can help reduce the need for purchased feeds in livestock production systems, when finishing cattle on pasture. Our objective was to evaluate the influence of stocking density and grazing stockpiled forage on performance of yearling steers during winter. Three grasslands were winter grazed for two years: I, naturalized pastureland, and II and III, sown and managed for hay production during the growing season but grazed in winter. Two stocking densities were used: low 7.41 and high 12.35 steers ha−1. Herbage mass was estimated before and after each grazing event, and disappearance (consumption, weathering, and trampling) was the difference between both. Forage mass and residual differed by stocking density (SD), year (YR), and grazing interval (GI), and disappearance differed by YR and GI. Grass and dead constituents of botanical composition differed by YR and GI. No differences were found for legumes and forbs. CP differed by YR and GI, and NDF and ADF differed only by YR. Steer average daily gain was 0.15 kg d−1in 2011 and 0.68 kg d−1in 2012 and varied by YR and GI. Acceptable gains in 2012 may be a product of environmental conditions that influenced herbage mass and nutritive value during stockpile and animal behavior during winter.

“…They attributed the increase in CP to the leaching of other constituents, whereas CP remains in the dead material, thus increasing its representative percentage. Earlier work reported an increase in CP concentration of late-summer, N-fertilized tall fescue swards in November or December (Taylor and Templeton, 1976;Gerrish et al, 1994) and a decline in the CP concentrations during the subsequent winter months (Bagley, 1979;Collins and Balasko, 1981b;Kallenbach et al, 2003;Curtis et al, 2008;Meyer et al, 2009).…”

Nitrogen Fertilization Rates Influence Stockpiled Tall Fescue Forage through Winter

et al. 2017

Tall fescue [Lolium arundinaceum (Schreb.) Darbyish.] can be autumn stockpiled to extend the grazing season. The objectives of this study were to determine (i) optimum mid‐August N fertilization rate for stockpiled yield with or without red clover (Trifolium pratense L.), (ii) if mid‐August N applications affect the persistence of red clover in a mixed sward, (iii) how N fertilization rates affect total ergot alkaloids (TEA) in November, and (iv) if N fertilization rates and harvest months affect nutritive value through winter. At the University of Missouri Forage Systems Research Center near Linneus, MO, five N fertilization rates were applied in mid‐August and forage was harvested the following November through March. Dry matter yield, crude protein (CP), and in vitro true digestibility (IVTD) were determined for each sampling date. Each November, TEA were measured from tall fescue‐only plots. Red clover densities were determined each June. Stockpiled yields increased with increasing N fertilization rates up to 168 kg N ha−1. Red clover neither impaired nor improved stockpiled forage yield. Red clover densities decreased linearly as N fertilization rate increased the previous August. Sward type affected nutritive value minimally. Losses in CP and IVTD through winter averaged 20 and 60 g kg−1, respectively, over the 4 yr. Application of 56 kg N ha−1 provided forage with CP concentrations that would support nonlactating beef cows. Fertilization rates of ≥112 kg N ha−1 resulted in November TEA concentrations that are toxic to grazing livestock. For optimum stockpiled forage yields, forage should be fertilized with <112 kg N ha−1 and grazed before January.
