Brief Summary of Minutes of Annual Meeting

Full 2014/2015 annual report attached as "Copy of Minutes" file below. Dr. Deb Hamernik (Administrative Advisor) addressed the group and explained that some groups invite USDA-NIFA personnel to attend these meetings by conference call or adobe connect. The consensus of the group was that we should invite Dr. Steve Smith, the program coordinator for USDA-NIFA systems work in the beef cattle area to join the 2016 meeting. Preliminary results of studies related to each objective were discussed by each group member. One of the experiments implemented this year to address objective 2 was implemented in 3 locations in Kansas and 3 locations in Nebraska. The preliminary results of this collaborative project were very different across locations. Additional collaborative project ideas were discussed for objectives 3 and 5. The meeting next year will be held in Hays, KS and will likely be held after the Grazing Conference in Kearney, NE.

Objectives List objective(s) worked on. The objectives listed in the project are: 1. Optimize the utilization of crop residues by grazing and harvesting and determine the effects on agroecosystems. 2. Evaluate strategies to increase efficient use and productivity of range and pasturelands through strategic timing and density of stocking and shifting species composition to more productive species. 3. Evaluate effects of integrating annual forage crops into year-round forage systems for beef production. 4. Develop innovative beef systems that match shifting forage resources. 5. Conduct multi-faceted education/extension program to disseminate research results, to include extension papers as well as regional conferences on the use of crop residues, annual forages, and range and pastureland by livestock. Accomplishments Nebraska Short-term outcomes: • Objective 1 o Beef producers can graze corn residue as a low cost feed option to improve sustainability without detrimental effects on subsequent corn grain productivity. o Average daily gains of calves grazing residue and supplemented with distillers grains can be predicted with reasonable accuracy. o Metabolizable protein supplementation with rumen undegradable protein is a key determinant in gains of growing calves grazing corn residue. o Harvesting methods which leave stems in the field result in higher quality residue bales. • Objective 2 o Measured dry forage mass of 4226 kg ha-1 in unfertilized smooth bromegrass stands on 2 June 2015 before interseeding annual warm-season grasses on 9 June 2015. The value is similar to other forage mass data we have collected in unfertilized smooth bromegrass pastures at this location. o Soil moisture content at depths of 0-15 and 15-45 cm average 19% 1 d after planting on 10 June 2015. o Annual warm-season grass establishment success varied with species. Seedlings m-1 row measured 30 d after planting on 7 July 2015 averaged 4 for corn, 18 for forage sorghum, 27 for sudangrass, 28 for sorghum-sudangrass, and 58 for pearl millet. o After 5 years of treatment application on Sandhills meadow, there is no difference in botanical composition and aboveground plant production among grazing systems (mob grazing, simple rotation grazing, and continuous grazing); and trampling of standing live vegetation is the greatest and harvest efficiency and yearling weight gain are the lowest for mob grazing. o On upland Sandhills range, grazing treatments (season-long continuous, 4-pasture deferred rotation, and 50-pasture rotation) have resulted in significant differences in grazing distribution with the 50-pasture rotation resulting in the most uniform distribution and continuous grazing the least. Effect of a heavy stocking rate (vs. moderate) is trending towards lower annual plant production. Length of grazing period (150 vs. 40 vs. 3 days) has not affected aboveground plant production. • Objective 3 o Late summer planted double cropped annual forages comprised of a mix of cool season grasses and brassicas can be a source of high quality forage and be used to background growing calves. Steers weighing 250 to 300 kg appear to gain 0.68 to 1 kg/d in Nov and December. However, herbicide strategy has a major impact on success of double crop forages, especially brassica species. • Objective 4 o Pregnancy rates of cows wintered on corn residue while nursing calves were adequate (90 – 100%), but additional numbers are needed to determine real effects of wintering system on reproductive performance. o Preliminary data suggest that wintering summer-calving pairs on cornstalk residue as part of an intensively managed system may result in cow BW and BCS losses compared to feeding pairs in a drylot. o Any negative changes in BW or BCS may be less of a hindrance on reproduction provided losses occur well after the breeding season and cows are in adequate BCS (? 5.0) prior to calving. o Daily gains for calves wintered on cornstalks with their dams may be similar to or less than those managed in a drylot, but delaying weaning beyond a conventional age (205 d) may increase weaning weight. o Complete sugarbeets can be mixed into a complete diet with wheat straw and wet distillers grains to maintain gestating beef cows on a limit fed diet. • Objective 5 o Research update articles have been disseminated to producers on forage cocktail mixtures. Accomplishments South Dakota Short-term outcomes: • Objective 1 o 45 corn hybrids were evaluated for yield and quality for corn and beef production. • Objective 3 o Experiments were initiated to evaluate impacts of stocking rate on performance and N excretion while grazing cover crops o An experiment was initiated evaluating cover crop mixtures for grazing cattle. • Objective 5 o Producer tours were given to show the progress of the cover crops. Nebraska Outputs: • 6 peer-reviewed journal articles • 4 professional presentations • 9 scientific abstracts • 21 research reports or proceedings • 1 popular press article • 7 webinars Accomplishments Illinois Short-term outcomes: • Objective 1 o Four methods of processing corn stalk residue were determined to have similar impacts on cattle performance • Objective 4 o MaxQ and KY-31 tall fescue were determined to have similar digestibility. Differences in cattle performance when grazing the two cultivars are not due to digestibility differences. • Objective 5 o Two field days were conducted to share the research results from Objectives 1 and 4 so producers could implement best management practices based on research. Milestones: • Research has been initiated and economic evaluation is ongoing. Project results have been presented at scientific meetings. Impacts: • Additional means of harvesting corn stover will be available for producers to determine the best practice for within their system. Producers are already incorporating these results. Accomplishments Kansas Short-term outcomes: • Objective 2 o Intensive early stocking rates were compared to continuous stocking rates on native pasture. Cow body condition score and calf weights were similar for both treatments. Yearling heifers also had similar gains regardless of treatment. o Legumes were interseeded into four tall fescue cultivars with varying endophyte status. Grazing will begin in 2016. o Warm season annual grasses were seeded into cool season perennial western wheatgrass and tall fescue at three locations across Kansas as part of a joint project with Nebraska where annuals were interseeded into cool season grasses across three locations. • Objective 5 o Extension meetings were conducted on research results of cover crop utilization for cattle and integrating crops and livestock. Approximately 450 producers attended. Kansas Outputs: Webinar for Kansas agriculture agents about fall annual forages for cattle production. 10 listened live, but the webinar is posted on the internal website for future agent visits. • Potentially toxic forage crops for livestock extension publication – MF3244, currently in publication department with estimated online publication date of October 2015 • AgToday radio interview about fall forage for cattle. • Davis. C, D. Presley, J. Farney, G. Sassenthrath. 2015. Evaluating multi-species cover crops for forage production. In: SEARC Agricultural Research 2015. Kansas State Univ. Agric. Exp. Stn. and Coop. Extn. Serv., Manhattan, KS. 76p Nebraska Activities: • Objective 1 o Ongoing work at the West Central Water Research Field Laboratory near Brule, NE and at the Monsanto Water Learning Center near Gothenburg, NE continues where research experiments aims to determine the effects of corn residue by grazing and baling. o The impacts of grazing cornstalk residue in 3 tillage methods on subsequent crops of corn, dry edible beans, and sugarbeets were evaluated. One year of data is collected. Subsequent yield was not different in any crop between grazing or not grazed. However, yield was greater for conventional tillage and zone tillage compared to no tillage. o Harvesting methods which collect different proportions of plant parts were evaluated. o Supplementation strategies of calves grazing residue were evaluated. o Collaborated with Iowa State University to submit a NIFA-CAP grant focused on integrating cropping and livestock systems using corn residue (Objective 1), double crop annual forages (Objective 3), and summer confinement of cows (Objective 4). • Objective 2 o Establishment of a project to evaluate success of interseeding annual warm-season grasses into existing cool-season grass pastures at three locations in Nebraska (Mead, North Platte, and Sidney) and three locations in Kansas (Parsons, Manhattan, and Hays). o Establishment of the multi-state experiment on interseeding annual warm-season grasses into existing cool-season grass pastures at Mead, Nebraska. o Collected and analyzed data from the first year of the interseeding experiment at Mead including measurements of forage production from smooth bromegrass before interseeding, soil moisture before planting, soil moisture 45 days after planting, annual warm-season establishment 30 days after planting, forage mass 45 days after planting, and forage functional composition (seeded species, cool-season grasses, and other species) 45 days after planting. o Established the interseeded annual warm-season grass experiment at Mead with a Great Plains No-Till Drill. Great Plains Ag is a Salina, Kansas based company that specializes in seeding equipment. o Continued the grazing studies on meadow and upland range at UNL’s Barta Brothers Ranch. The sixth year of field data is being collected in 2015. • Objective 3 o Summer annual forage mixtures (forage cocktails) were compared to monoculture species in a semi-arid region in a dryland cropping rotation. Forages were evaluated for dry matter yield, crude protein, and total digestible nutrients. One year of data has been collected. There were no statistical differences in any mixtures or monocultures in tonnage produced, total digestible nutrients or acid detergent fiber. Crude protein was improved in the mixtures compared to the monocultures. o Collaborated with Kanas State University to submit a NCR-SARE grant focused on strengthening management guidelines for use of double cropped annual forages including species selection and grazing management. • Objective 4 o A second year of comparing summer calving cows wintered in a dry lot or wintered on corn residue was initiated. o Gestating beef cows were limit fed energy dense diets containing wheat straw, complete sugar beets and wet distillers grains or wheat straw, corn, and wet distillers grains. Diets were balanced to be isoenergetic. No differences in BCS change or BW were detected after a 47-d trial. • Objective 5 o Research from Objective 4 has been presented at 10 producer meeting and 3 producer conferences. o 2 field days related to Objective 1 were held at the West Central Water Research Field Laboratory. o Research results from the grazing strategy studies in Objective 2 have been presented at the 2015 Barta Brothers Field Day, the 2014 Gudmundsen Sandhills Laboratory Open House, the 2014 Nebraska Grazing Conference, and multiple producer meetings. o Collaborated with University of Nebraska-Lincoln Extension to submit a USDA-Risk Management Agency Risk Management Education Partnership proposal to provide comprehensive risk management education to livestock and forage producers in 2015-16. Milestones: • Objective 1 o Fields were established or evaluations of established fields continued where residue was removed either by grazing or baling. Soil samples were collected from fields. • Objective 2 o Multistate interseeding projects were initiated as described in the Activities section above. o Data on the long-term impacts of grazing strategy on vegetation productivity and utilization, harvest efficiency, and rangeland health continues to be collected on meadow and upland range at the Barta Brothers Ranch. • Objective 3 o Purchased seed for the interseeding annual warm-season grass project, which is used across all locations, from Green Cover Seed in Bladen, Nebraska, a local source specializing in no-till cover crop seed and cover crop seed mixes. o Baseline soil measurements were taken on fields where cover crop research will be occurring. • Objective 4 o Two treatments were imposed on multiparous, cross-bred beef cows that calve in July: • Cows and cow/calf pairs are managed in a drylot 365 days. • Cows and cow/calf pairs are managed in a drylot and graze corn residue. • At least three years of pregnancy data needs to be recorded. • Based on year one data, supplementation strategy may need adjusted to get comparable cow and calf performance. • Objective 5 o Received funding ($26,316) from the North Central Extension Risk Management Education Center to provide market risk management and cost of production training to cattle producers in Nebraska in 2015-16.
