Objective 2. Facilitate organization, synthesis, and integration of component-based research findings and supporting data.

The underlying premise of this objective is that project participants collaborate or work together in teams to build a component(s) of the relational aspects of animal protein production presented in the CLD. Participants will make/share data available to support the CLD work via a publicly accessible database.    Planned activities to meet this objective include: (1) identifying the types of data participants have or being generated in their current work and (2) designing and hosting a publicly accessible database for sharing project data by participants to facilitate development/integration of system components outlined in the CLD (figure 1) Note the figure is available from Ron Lacewell (r-lacewell@tamu.edu). The accomplishments towards achieving this objective include:

• Project participants continue to identify and update the nodes relevant to their work and also indicated sets of data they have available to share, as listed in table 1.
• Some examples of specific data available and/or current research activities by project participants to generate data for potential use in completing the CLD are listed below.
  • Arkansas: Work continues in using poultry litter as substrate to produce renewable energy via anaerobic digestion (B19). Recent work has focused on developing methods to reduce the contaminants in the effluent water from the digester so that it can be recycled back to the digester to dilute incoming litter, as well as adding a carbon source to the litter to increase the carbon to nitrogen ratio. Some results have been published as journal articles.
  • California: Meyer has been a liaison with Dr. Jones (FL) regarding data harmonization for the NARDN-HD project, and reviewed the data dictionary proposed for dairy.
  • Iowa: A review of 250+ journal papers focused on mitigation technologies for odor, gas and particulate matter emissions from livestock production was completed and published in an Open Access article (Maurer et al, 2016). The study showed that only approximately only ~25% of research on mitigation technologies for odor, gases and particulate emissions from livestock farming was tested in field/farm conditions and the majority of research was completed for swine. The published study and associated data base (in form of spreadsheets) is an integral part of Extension website “Air Management Practices Assessment Tool (AMPAT) at Iowa State University serving public, farmers, livestock industry, regulatory agencies and other stakeholders.  Additional research is focusing on finding biomarkers of major livestock diseases in conjunction with the National Animal Disease Center in Ames, IA and USDA- APHIS-WS-National Wildlife Research Center in Fort Collins, CO. Microbial, feces, and breath biomarkers were identified warranting further development of approaches for non-invasive, fast detection of animal diseases. 
  • Idaho: Research is focused on mitigating gas emissions from manures by using polymers and anaerobic digestion of manures for biogas generation. They also conducted nutrient uptake research for which duckweed strains were cultivated on anaerobically digested dairy manure. Use of zeolites to retain nitrogen during composting treatment of dairy manure was evaluated and demonstrated. Through our efforts, new knowledge in the area of manure treatment has been generated, shared with peers, and disseminated to our stakeholders.
  • Kansas: Liu completed investigation of vegetative environmental buffers and ultraviolet light technology to reduce air pollutants from livestock facilities, and data will be published soon. We also estimated contributions of regional agricultural sources to air quality (PM2.5 and O3) through receptor modeling, and has published one journal paper on this topic. Systematic review and meta-analysis of NH3 and CH4 emissions from cattle operations were conducted, and two manuscripts were under review and will be published soon
  • Michigan: Powers and Safferman, with Texas member Auvermann have cooperatively advised a graduate student through the development of a nutritional model, and are working on expansion of the model to be better able to integrate additional loops and nodes in the future. Safferman maintains online, publically available decision support tools to convert animal waste into a resource. Specifically the Michigan Waste Biomass Inventory to Support Renewable Energy (Inventory) maps organic wastes (including livestock manure) in Michigan and conducts preliminary energy modeling. Included in the Inventory is manure from animal agriculture facilities. The Anaerobic Digestion Development Iterative Tool and the Combustion Renewable Energy Development Iterative Tool to model the economic, renewable energy production, and greenhouse gas emissions reduction from using organic residuals from farms. Safferman continues to investigate manure constituent separation using pretreatment and membrane systems. Pretreatment can be anaerobic digestion or coagulation/flocculation followed by filtration. Separated are clean water, solids, and nutrients. Examining the economics of the technology and barriers to implementation. New research by Safferman emphasizes phosphorus movement in soil, including that originating from manure. Members took a leadership role in the Michigan Water Federation Sustainable Energy Committee to share applicable technologies and community energy generation. As a result, new project participants and collaborators for grant opportunities have been identified, each of whom build on the skills of current membership.
  • Minnesota: A multidisciplinary research team is measuring energy use on dairy farms and swine production farms. The team is also installing photovoltaic solar systems and monitoring their energy production. The overall goal of the research team is to reduce energy use for swine and dairy production by identifying major energy uses and to increase use of renewable energy for swine and dairy production. Data collection and analysis is ongoing. A new project is to install another photovoltaic system and use the energy for cooling in the warm weather and heating in cool weather.
  • Missouri: Solid/liquid separation technologies and practicality, additional water/nutrient extraction, co-digestion potential to improve profits, and anaerobic digestion for mitigation of veterinary antibiotics are current research topics, whose data will support S1032 loops and nodes.
  • North Carolina: Kick has made progress in causal modeling of food insecurity for the world at large by connecting a huge number of variables down to a tractable set of around 40. Data from the World Bank, FAO, UNESCO etc were collected, coded, and underanalysis performed. Results from assessment of a range of analytial models will be integrated. Data, results and manuscripts will be placed in files and made available to scientific community and interested others. Classen, in conjunction with a graduate student, has made progress in integrating multiple analytical methods regarding technology performance and adoption, including Economic Input Output analysis, Life Cycle Assessment, and Techno-Economic Analysis. The outline of a method to synthesize these results has been created. A two stage reactor was built to (1) strip carbon dioxide from wastewater and (2) transfer gaseous ammonia from the wastewater across a hydrophobic gas-permeable membrane to a dilute acid stripping solution. A five-day test revealed significant ammonia recovery in the stripping solution. A model of the recovery system will be constructed and used to estimate the regional potential for ammonia recovery.
  • North Dakota: Nanoparticles were being applied at different application rates and encapsulation to investigate their effectiveness to mitigate hydrogen sulfide and GHG. The microbial analysis of manure was carried out using bacterial plate counts and RT-PCR methods. Morphology and chemical composition of alginate-nZnO beads were analyzed by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), and X-ray Photoelectron Spectroscopy (XPS). Alginate-nZnO beads or bare nZnO proved to be an effective NP in reducing H2S (up to 99%), CH4 (49-72%); and CO2 (46-62%) from manure stored under anaerobic conditions and these reductions are likely due to the microbial inhibitory effect from nZnO, as well as chemical conversion.
  • South Dakota: In conjunction with S1032 colleagues in Nebraska and Missouri, in addition to others, the Pathways Project was completed wherein the modes of information transfer among manure nutrient management professionals were surveyed. In addition to identifying the main means that different populations around an issue gain and share information, barriers to adoption were also identified. A journal publication is being prepared.
  • Texas: Researchers completed a comparative, wean-to-harvest, life-cycle analysis of five different beef-production systems characteristic of the Texas Panhandle: 100% native grass, grass to feedyard, improved pasture to feedyard, native grass to improved pasture to feedyard, and feedyard only.  Wean-to-harvest emissions of CO₂ equivalents per unit beef produced were lowest for the feedyard-only system (4.84 kg CO₂e/kg gain) compared to the other systems, with grass-only production emitting the most (26.49 kg CO₂e/kg gain).  The work was the basis of a dissertation and PhD conferred by West Texas A&M University. Casey continued measurements of N₂O, CH₄ and CO₂ fluxes from feedyard pen surfaces, and in collaboration with USDA-ARS engineers and scientists is cooperating in the study of N₂O emission under controlled conditions using a Los Gatos N₂O/CO continuous analyzer and 6, 1 m²
  • Virginia: This past year, experiments with lab scale thermophilic anaerobic digesters to evaluate influence of commonly used antibiotics in dairies on biogas production were conducted. A Master’s thesis and journal publications are being prepared.

Objective 3. Discover (reveal), substantiate, and interpret the broader impacts of component-level modifications to animal production systems.

In California, the amount of silage shrink between when material is deposited from the field for ensiling and when it is fed-out has been quantified. This has been transferred through eLearning decision support systems to aid dairy operators and consultants to understand importance of collecting representative samples and quantification of material applied to land and removed as crops.

Causal modelling in North Carolina by Kick is underway. The dataset includes 40 variables from over 200 countries. Through Structure Equation Modeling, multiplication of paths permits assessment of direct and indirect relationships among all variables, which include national geography, world power of nations, forms of national capital, agricultural production, food (in)security, obesity and environment outcomes. The model will predict how changes in any variable will change all others. Food security, obesity and environment are key dependent variables. Results suggest substantial “slippage” in the production of food production and distribution to food insecure populations. Food waste, food thievery, failure of state to deliver food to populations at risk are serious prolems. Also, food provided may generate problems with obesity among recipients. An overhaul of food production and distribution system is recommended.

In Michigan, data from a swine feeding study that measured dietary impact on air emissions and nutrient excretion continues to be modeled to reveal the longer term impact on soil nutrient accumulation and potential water quality. This work is in the early stages but will add in the feedback loops to the portion of the CLD under development (Objective 2).

In Missouri, researchers analyzed potentials and practicality to co-digest low amount of waste-grease for the producer. The solid/liquid separation can improve options for livestock production to reduce manure storage and make more flexible nutrient management (land application and nutrient export), and potential water recycling.  The antibiotic degradation research can improve how manure nutrient applied in the field and reduce risks of antibiotic pollutions.  

In Texas, Colorado, New Mexico, Oklahoma, Kansas, and Nebraska, researchers have begun a five-year Coordinated Agricultural Project (CAP) under USDA-NIFA’s Water for Agriculture program, focusing on conservation of the non-recharged portion of the Ogallala Aquifer and the crop and livestock production that depends on it.  Social and economic modeling of a variety of producer scenarios will inform the development and evaluation of policies to encourage adoption of ground water conservation strategies.
