Participants
Members attending: Ken Moore and Jim Russell from Iowa State University; Robert Kallenbach, Fred Martz, Jerry Nelson, and Craig Roberts from the University of Missouri; Dale Blasi, Walt Fick, Lyle Lomas, and Joe Moyer from Kansas State University; Don Adams, Bruce Anderson, Terry Klopfenstein, Martin Massengale, Lowell Moser, Rick Rasby, and Walt Schacht from the University of Nebraska; and Pat Carr from North Dakota State University with Administrators, Darrell Nelson and Henry Tyrrell. Also attending were Pam Murray from the Center for Grassland Studies at the University of Nebraska and Todd White, a post-doctoral research associate from Iowa State University.
The 2003 meeting of the NC-225 regional project was held in Columbia, Missouri. Primary activities of this meeting were a discussion of the renewal of this project and progress reports for the research and outreach objectives in the current project.
The title of the renewed project will be Beef Cattle Grazing Systems that Improve Production and Profitability While Minimizing Risk and Environmental Impacts. The objectives will be: 1) To develop strategies that better match animal nutrient requirements to the quantity and nutritional value of the forage supply as affected by: forage production; nutrient supplementation; and animal management practices; and 2) To develop educational materials and programs to improve decision-making for grazing-based beef production systems by: creating a database that integrates the composition of forages in grazing systems in the North Central region; conducting systems-based educational programs on integrated forage/cattle management systems for cattle producers; and developing an educational program on the utilization of grain co-products in grazing-based cattle production systems. A draft of a proposal will be prepared by Jim Russell and Ken Moore from Iowa; Terry Klopfenstein, Don Adams, Walt Schacht and Bruce Anderson from Nebraska; Dale Blasi from Kansas and Rob Kallenbach from Missouri to be placed on the WEB for review by contributing stations. All materials will be sent to Jim Russell by August 1, 2003.
It was decided that 2004 meeting of the committee will be in Lewis, Iowa June 17-18 at the Armstrong Research and Demonstration Farm, with Jim Russell of Iowa and Joe Moyer of Kansas State serving as the committees chair and secretary, respectively.
Station reports followed under the project objectives. The overall objective of NC-225 is to develop concepts and systems that increase the uniformity of the year-round forage supply and the efficacy of forage, animal and grazing management to improve the profitability of beef production. Specific objectives include: 1) To quantify production and economic impacts, including risk, of beef cow-calf systems that better match animal nutrient requirements to the quantity and nutritional value of the forage supply; 2) To improve the profitability and productivity of cow-calf systems by identifying alternative forage species and grazing management to extend the length of the grazing season; 3) To develop strategies for using forage legumes to improve the agronomic, animal performance, environmental and economic characteristics of forage-beef systems; and 4) To develop a systems-based educational program on integrated forage/cattle management systems for cow-calf producers in the four state region.

Accomplishments
Objective 1. The Iowa station found that bred heifers grazing stockpiled endophyte-free tall fescue-red clover forage had body weight gains that were 50 to 100% greater than their target weight gains with 88% less supplemental corn gluten feed and 27% lower daily costs than heifers fed hay and corn gluten feed to meet their target weight gains in a dry lot during winter. Iowa also reported that a year-round grazing system using spring- and fall-calving cows with stocker cattle was more profitable than a conventional system with summer grazing of grass-legume pastures, fall grazing of corn crop residues, and winter hay feeding in three of ten years because of the effects of stocker profitability and hay and land costs.
The Nebraska station reported that pregnant yearling heifers grazing Sandhill range and supplemented to meet metabolizable protein (MP) requirements had no differences in body weight or body condition score, but had greater pregnancy rates than heifers supplemented to meet crude protein (CP) requirements, increasing the value of each bred heifer in the MP treatment by $13.64 over heifers receiving the CP treatment. Nebraska also reported that March-calving cows in the Sandhills supplemented with protein during winter had lower weaning rates, but higher weaning weights than those not supplemented with protein. Nebraska also reported that steers from cows wintered on corn stalks and finished as stockers after grazing cornstalks and pasture during winter and summer had greater daily gains, carcass weights and ribeye areas, but lower marbling scores, quality grades, and sensory scores than calves finished after weaning.
To integrate the quantity and quality of forages in the North Central Region with the nutrient needs, the Kansas station has developed the KansasGrazer software (available at www.oznet.ksu.edu/forage/ksgrazer.htm). To enhance its utility, a tutorial was developed and is accessible from the programs opening screen through the Help button. The software will be demonstrated at grazing schools and conferences in 2004.
Objective 2. The Iowa station reported on the establishment plots of five legume, six cool-season grass, and four warm-season grass species in the initiation of a multi-state project with Missouri and Kansas comparing the nutritional value of these forages in a winter stockpiled grazing experiment. Iowa also observed that grazing corn crop residues when soils were not frozen increased soil penetration resistance and roughness, but reduced yield of soybeans planted with no tillage by 3.5 bu/acre in one of three years.
The Kansas station observed similar forage dry matter masses and grazing gains in stocker steer grazing crabgrass fertilized with additional N or interseeded with lespedeza over three years in a wheat-crabgrass double-crop system. In 1999, finishing gains and ribeye areas were higher for steers that grazed pastures interseeded with lespedeza.
The Missouri station observed that fall-calving cows grazing annual ryegrass/cereal rye pastures or stockpiled E- tall fescue pastures had improved body condition scores at less expense than traditional hay feeding. Missouri also reported that tall fescue infected with a native endophyte (K31 E+) had greater yields and higher concentrations of ergovaline in early winter than patented non-toxic endophyte (HiMag E++), and with no endophyte (HiMag E-) cultivars. While all cultivars had minimal losses forage yield and quality over winter, ergovaline levels in K31 E+ declined by more than 85% between December and March.
The Nebraska station observed that while summer grazing date did not affect yield of Sandhills upland vegetation, forage CP and in vitro digestible organic matter concentrations during dormant-season grazing and yields of cool-season grasses the following season decreased as the fall stocking rate increased from 1 to 3 AUM/ha. Nebraska also reported that plant yield, vigor and density of prairie sandreed and sand bluestem were more greatly reduced by drought-stress in June and July and defoliation at 90% of the current years growth than drought-stress in other summer months and at lighter defoliation levels. Nebraska also found that May grazing of big bluestem had no effects on cumulative pre-grazing yields, but greater herbage disappearance, harvest efficiency, and leaf:stem ratio than no grazing. Grazing at the vegetative stage in June increased pre-grazing yields, herbage disappearance, harvest efficiency, and leaf:stem ratio compared to grazing at the elongation stage. In addition, Nebraska observed that net photosynthesis declined more in big bluestem than smooth bromegrass grown under shade.
The North Dakota Station observed that barley may produce a comparable yield of forage with higher CP and total digestible nutrient (TDN) concentrations compared with oats, emmer, spelt, rye, and triticale in soils containing greater than 90 kg N/ha in the 0- to 60-cm soil depth. North Dakota also reported that intercropping spring barley, oat, and triticale with winter cereals increased forage CP and TDN concentrations and provides limited quantities of forage for fall grazing. However, total forage production is reduced by 10% when spring and winter cereals are seeded together compared with seeding spring cereals alone.
The Ohio Station observed that a non-Bt corn variety had greater losses of harvestable dry matter from standing corn over winter than a near iso-genic variety and a late maturity variety. Ohio also observed gains of 96.5 lb/acre values at $1.00/lb for dairy heifers grazing annual rye with 3 lb of a 13% CP heifer supplement.
Objective 3. The Iowa Station observed that plant species richness, Shannon diversity and evenness were significantly and negatively related to the concentration of all plant nutrients except Phosphorus in the soil. Iowa also reported legumes to be greatest in zones with intermediate soil electrical conductivity values, slopes greater than 10%, and the greatest diversity of leguminous species.
The Kansas Station observed that seeding ARS-2620 rhizomatous and standard birdsfoot trefoil, white clover, red clover, kura, subclover, and Alfagraze alfalfa cultivars into endophyte-infected tall fescue improved forage nutritive quality and annual distribution while reducing N fertilizer requirement and severity of fescue toxicosis.
The Missouri station observed that steers grazing pastures containing a rhizomatous (ARS-2622) or common (Norcen) variety seeded with tall fescue had greater daily body weight gains than those grazing tall fescue.
The Nebraska station observed that yearling heifers grazing pastures with different proportions of birdsfoot trefoil in the stand (5 to 45%) utilized birdsfoot trefoil at similar levels (45 to 60%) regardless of the proportion of birdsfoot trefoil in the stand.
The North Dakota station observed that of 30 legume species, those with the greatest ability to reseed in an undisturbed seed bed included black medic, crimson clover, Persian clover, balansa clover, red clover, and birdsfoot trefoil. Forage DM production for alfalfa, birdsfoot trefoil, and red clover were 5.6, 2.7, and 3.4 Mg DM/ha, but less than 1 Mg/ha for all other legume species. North Dakota also found that seedlings of rhizomatous birdsfoot trefoil did not grow well in contrast to the common birdsfoot trefoil hybrid, Norcen.
Objective 4. To transfer technologies to improve the profitability of beef cow-calf production by extending the grazing season, a conference series titled Integrating Forage & Cattle Resources was held in Bismarck, ND; Chadron, NE; Moline IL; and St. Joseph, MO in late fall of 2002. This series resulted from a novel collaboration of the NC-225 Improved Grazing Systems for Beef Cattle Production project, Northern Integrated Resource Management group in beef cattle extension, and National Cattlemens Beef Association, with the goal of increasing profitability of beef cow-calf production through improved grazing practices. Members of the NC-225 project participated as speakers and authors of posters and the Making Extended Grazing Work in publication for the states of Iowa, Nebraska, North Dakota and Ohio. The total audience of 495 beef cattle producers, extension specialists, and NRCS personnel at the four locations came from at least 10 states in the North Central Region.
The Nebraska station reported that pregnant yearling heifers grazing Sandhill range and supplemented to meet metabolizable protein (MP) requirements had no differences in body weight or body condition score, but had greater pregnancy rates than heifers supplemented to meet crude protein (CP) requirements, increasing the value of each bred heifer in the MP treatment by $13.64 over heifers receiving the CP treatment.
