  1. Annual update of normative values for N, P and K in animal manure

    Christian Friis Børsting, Martin Tang Sørensen, Peter Lund, Anne Louise Frydendahl Hellwing, Marleen Elise van der Heide, Peter Kai & Michael Jørgen Hansen

    Every year the normative values for N, P and K in animal manure is updated. These values are based upon mean values from commercial farms for feed intake and composition, as well as for the production for a large variety of farm animal categories. Furthermore, literature values are used for the composition of the animal products (meat from different species and eggs), whereas milk composition is measured on farms. Emission factors from stables and storage of manure are taken from the literature.
    The project is funded by the Danish Agricultural Agency as part of AU's public sector service.Description

  6. On-farm monitoring of methane from dairy cows is a prerequisite for implementation of mitigation strategies on animal, farm and national level

    Mogens Sandø Lund, Goutam Sahana, Jan Lassen, Peter Lund, Hanne Bang Bligaard, Troels Kristensen, Line Hjortø, Kevin Byskov & Tavs Nyord

    Vi vil sænke metanudledningen fra mælkeproduktionen i Danmark med omkring 171.875 tons CO2 ækv i 2030 svarende til 5 % af det nuværende niveau. Udgangspunktet er udviklingen af en målemetode til individuelle, kvantitative målinger af metanudskillelsen fra malkekoen direkte i stalden. Metoden vil give præcise målinger på et meget stort antal køer i danske malkekvægsbesætninger til en lav pris. Dette giver en unik fremtidssikret dataplatform, som er udgangspunktet for de øvrige aktiviteter. Derfor kan projekt som noget helt unikt på verdensplan udvikle og implementere et avlsindeks i kvægbruget, som gør det muligt at nedbringe udledningen fra malkekvægssektoren gennem et systematisk avlsarbejde under hensyntagen til koens fysiologi og sundhed. Data fra den enkelte ko kombineret med øvrige produktionsdata fra besætningen udnyttes til af identificere yderlige virkemidler som den enkelte mælkeproducent kan implementere og få dokumenteret i bedriftens klimaregnskab. Endvidere giver disse data et grundlag for løbende at kunne inkludere bedriftsspecifikke tiltag i Danmarks afrapportering til FNs klimapanel, IPCC. Opsamling af data og udnyttelse til de beskrevne formål, kræver en multidisciplinær tilgang og et tæt samarbejde mellem partnere fra universitet og industri, hvilket kan opfyldes af projektgruppen.Description

  11. High nitrogen utilisation by phase feeding of protein

    Mogens Larsen, Martin Riis Weisbjerg, Martin Tang Sørensen & Peter Lund

    The purpose is to create scientific knowledge to divide a given amount of protein optimally throughout the lactation period and to demonstrate phase feeding of protein in different barn designs. Overall, the purpose is to increase the nitrogen utilisation in dairy cows for the benefit of resource utilisation, economy, water environment and climate.

    The basic idea of this project is to obtain significant positive effects on the dairy cows' milk production and nitrogen utilisation by phase feeding of protein throughout the lactation period. At present, knowledge is lacking about for how long the higher yield lasts after cessation of extra allocation of protein and which effect phase feeding has on nitrogen and feed utilisation during the lactation period. Furthermore, knowledge is lacking about whether a very short allocation of extra protein, e.g. 700 g/day in 3 or 7 days after calving, results in the desired effect on yield in early lactation. Short allocation is relevant in herds with no automatic allocation of concentrate.

    The activities are organised in work packages 1 and 2 within the framework of AU-Foulum and SEGES-Cattle, respectively. Work package 1 includes activities that create knowledge to divide a given amount of protein optimally throughout the lactation period. Work package 2 includes activities that demonstrate phase feeding of protein in different barn designs.

  12. Udvikling af model for kvægbesætningens udledning af enterisk metan under forskellige management strategier

    Søren Østergaard, Anne Braad Kudahl, Martin Riis Weisbjerg, Jan Tind Sørensen, Vivi Mørkøre Thorup, Peter Lund, Lisbeth Mogensen, Morten Kargo & Long Chen

    En fortsat stor dansk mælkeproduktion kan være model for andre lande, hvis Danmark kan finde klimaløsninger, som dels er anvendelige i praksis, dels er effektive, både når man ser på bedriftens samlede klimagas udledning og på det økonomiske perspektiv. Den enkelte malkekvægbesætnings produktions-og managementsystem er et centralt og nødvendigt delsystem i, at kunne forstå og kvantificere den samlede danske klimabelastning for produktion af mælk og kød. Projektets hovedaktivitet er at udvikle en ny besætningsmodel til simulering af tekniske og økonomiske konsekvenser af managementtiltag til reduktion af klimaaftryk i malkekvægsbesætninger.

  15. Identification and elucidation of bioactivity of new compounds excreted into milk as the result of introduction of novel feeds and/or anti-methanogenic feed additives in diets for cattle

    Mette Olaf Nielsen, Marie Rønn, Natalja Nørskov, Stig Purup, Peter Lund, Christine Brøkner, Peter Langborg Wejse & Henrik Jørgen Andersen

    It is the aim of the PhD project to develop and validate (in this PhD: on 3-4 new feed additives) a methodological approach for identification and safety assessment of unknown compounds that potentially could be excreted into milk (or accumulated in meat) when novel feed additives are being introduced to markedly reduce enteric methane emission to be able to comply with climate goals defined by the EU, the Danish government, as well as the dairy/beef industry.
    Methane reduction efficiency and safety assessed of 3-4 new anti-methanogenic feed additives, which are presently being researched at AU as part of IFD projects: compound X and Nordic hemisphere macroalgae. 1) Validated targeted methods will be refined to accurately quantify compound X and possible break-down products in biological samples (e.g. blood, milk and meat). 2) Untargeted metabolomics approaches will be used to identify hitherto unknown compounds excreted into milk, when macroalgae or compound X based feed additives are included in cow diets.

  16. Forage preservation for premium protein quality

    Marianne Johansen, Martin Riis Weisbjerg & Egil Prestløkken

    The project EngProt addresses the challenge of increasing the proportion of domestic and human-inedible protein sources in Norwegian ruminant diets. Presently, silages contribute the major part of the crude protein fraction, but their direct and indirect supply of amino acids that can be absorbed in the small intestine (AAT) is very variable. Cost-efficient measures in forage production that sustain a high silage AAT value will be sought developed in the project, and the basic idea is that highly controlled, restricted fermentation during preservation has a considerable potential in this regard. Previous research has confirmed that crop wilting and/or application of acid additives and salts restrict fermentation and preserve water soluble carbohydrates, prevent proteolysis and improve silage AAT. There are indications that both the fraction of rumen undegraded protein and microbial protein synthesis are affected in situ, but positive responses in milk production remain to be validated. These relationships will be investigated in digesta flow studies and production experiments with high yielding cows. Preservation experiments at laboratory scale will be conducted in order to define targeted fermentation patterns for different crops and to find the best options for controlling fermentation. The findings from the experiments will lastly be inputs to feed optimizing models prescribing diets at differing milk yields and then further analysed in a bio-economic linear
    programming model that establishes optimal farming systems and economic rewards of different silage productions regimes. The model also produces outputs that enable an investigation of constraints and environmental consequences of improved silage protein value in the Norwegian dairy milk production sector.

  19. Flycloud - digitalizing insect production

    Jan Værum Nørgaard, Ida Elisabeth Berggreen, Janne Møller Poulsen, Jane Lind, Carsten Lind, Johan Egsgaard, Emil Jakobsen & Jens Toppenberg

    The outcome of the project is a digital tool (to be named Flycloud) that collect realtime data from an industrial-scale Black Soldier Fly Larvae (BSFL) production and organize and visualize the data to make it more accessible for the production staff to monitor the production efficiency. The digital tool will link gas emission measurements and production parameters into key performance indicators (KPI), such as e.g. BSFL growth, feed utilization and emissions of GHG.

    First main target (WP1) is to identify the most important production and environment KPIs. In the next target (WP2 – the scientific part) we will create knowledge about the relationship between CO2, NH3 and O2 data and feed utilization and growth of BSFL. The next target (WP3) is to develop and test Flycloud by validating the sensors needed and develop software and algorithms. At last (WP4) the tools will be tested and optimized in the production facilities at Enorm Biofactory A/S.

    The experiments conducted in this project on digestion, metabolism and emissions of BSFL, will show the relationship between some of the KPIs e.g. emission of gasses vs. feed composition and feed composition vs. feed utilization. The results will tell how the larvae are utilizing different nutrient sources in the feed and make it possible to adjust the feeding if irregular data are shown on Flycloud that can be associated with the feed. This will make it possible to meet the same production standard in each batch.

  24. SeaBioAct

    Natalja Nørskov, Mette Olaf Nielsen & Annette Bruhn

    Current climate policies represent a serious threat to the cattle industry, since cattle account for appr. 75% of emission from Danish agriculture of the powerful greenhouse gas, methane. It has been discovered that a tropical red macroalgae, Asparagopsis taxiformis, when fed in small quantities to cattle, virtually blocks the enteric methane emission. Northern macroalgae species (eg. Saccharina latissima, Ascophyllum nodosum, Alaria esculenta) induced a partial suppression of methane formation in an in vitro system simulating rumen fermentation. The bioactive compounds responsible for this are as yet unknown, but their use as anti-methanogenic feed additives for ruminants could have enormous market potential – nationally and globally.

    Lene Stødkilde-Jørgensen & Søren Krogh Jensen

    The project will promote commercialisation of grass protein through optimisation of key elements in the production and through production of high value products for strengthening of the production economy. The best varieties of grass and clover will be identified through screening, analysis of protein content and biogas value of the residual fibre fraction. Harvest methods, which will preserve protein content and quality will be developed. In addition, different shredding techniques will investigated. Tannins will be extracted from the grass material, to establish whether a tannin-containing feed additive having a reducing effect on intestinal worm infections can be developed. The Product environmental footprint (PEF) will be documented.

  26. Biochar produced from bio-refined grass clover pulp for feed and technical purposes

    Andrej Saner

    The objective of this PhD project is to support a sustainable production of protein feed from grass by Green Protein Plant. The grass protein production is challenged in order to make a truly sustainable business case. Adding pyrolysis technology will result in production of both renewable energy and biochar. The produced energy will be integrated with the protein separation process and cover the internal energy demand of Green Protein plant. This will make the production independent of fossil energy and reduce the energy costs. The biochar, which is expected to be low in ash and thus of high quality, has potential high value market applications as toxin binder in the feed industry and as pollutant remover. Adding an extra high value product to the green biorefinery concept as well as reducing dependence on fossil energy will improve the economics and sustainability of green protein production and make it a viable business case.Description

  27. Strategies in grass silage production to mitigate enteric CH4 emissions from ruminants

    Peter Lund

    In this project we will develop strategies in grass silage production that mitigate enteric methane (CH4) emissions from ruminants. Globally, enteric CH4 is a significant contributor to greenhouse gas (GHG) emissions and it accounts for almost half of the total GHG emissions from Norwegian agriculture.

    Grass silage is the dominating preserved forage in ruminant diets in Norway and the practice used for grass silage production is very diverse, resulting in wide variation in characteristics such as chemical composition and nutritive value, and hence influence on enteric CH4 emissions. Consequently, finding ways to produce grass silage that minimise enteric CH4 emissions is an important strategy to reduce GHG emissions from Norwegian agriculture.

    Målet med SeaSus-protein er at udvikle 2-3 funktionelle proteinprodukter fra dansk tang ved at 1) teste effekten af bioraffinering (fermentering, ekstraktion og tørring) på kvaliteten af proteinprodukter fra fire nordiske tangarter: søsalat, sukkertang, vingetang og søl, samt 2) optimere metode(r) til ekstraktion af protein fra disse. Projektet vil klarlægge hvilke tangarter og bioraffineringsmetoder, der er mest optimale med hensyn til højt proteinudbytte, smag, fødevarefunktionelle egenskaber, proteinkvalitet og fordøjelighed. De mest lovende produkter vil blive testet i ost, både som smagsgiver (reduktion af salt, positiv på sundhed) og som erstatning for mælkeprotein (positiv på klima) samt i et farsprodukt. Da søsalatprotein er et nyt produkt på markedet og masseforekomster af søsalat skaber problemer i danske fjorde, vil projektet udvikle og demonstrere skånsom høst af søsalat i stor skala.

    Peter Lund, Martin Riis Weisbjerg, Ole Hojberg, Anne Louise Frydendahl Hellwing, Maria Holst Kjeldsen, Troels Kristensen, Samantha Joan Noel & Christian Friis Børsting

    We will validate existing additives and, in collaboration with the industry, start the development of new safe additives, which in the long term can ensure a significant reduction in methane without compromising the animal's health and milk quality.

    In the project we will establish the phenotype for the effective dairy cow so that this can be included in the future breeding goals. The use of new mitigation-tools depends entirely on the possibility of implementation on the individual farm. We will develop tools to document the real production of enteric methane on a cattle farm.Description

  32. Grass Biochar – production of energy from press pulp residue from green protein biorefining for operation of the refining process and production of valuable biochar

    Søren Krogh Jensen, Lene Stødkilde-Jørgensen, Morten Ambye-Jensen & Aidan Mark Smith

    The purpose of the Grass Biochar project is to use a combined Steam Drying and Pyrolysis process (DTP) to produce green energy to drive the bio-refining process while producing Biochar of the fiber fraction from grass protein production.
    Hereby, two barriers for spreading the green biorefining concept can be overcome:
    - that the process requires large amounts of energy, which should be green if production is to be climate-sustainable
    that a high value must be created of all factions if it is to be economically sustainable. Fractions of the pulp that are not suitable for cattle silage or biogas production, such as the late-developed grass with a high lignin content, as well as grasses from pastures and meadows that are only harvested once or twice per year, are excellently suitable for energy and biochar production using The DTP process.
    The integrated plant must contribute to making grass protein production flexible to implement according to local conditions and fully sustainable, both environmentally and economically, which can create the breakthrough for it in Denmark and abroad.

  34. Pigs without antibiotics: A pig model of colitis-complex diarrhea with focus on colonic microbial fermentation

    Tina Skau Nielsen, Ole Hojberg & Charlotte Lauridsen

    Diarrhea in weaned pigs is one of the major causes of antimicrobial use in pig production. When pigs are 7-12 weeks of age, heavier and therefore takes larger doses of antibiotics to treat than right after weaning, a second phase of diarrhea typically occurs; the colonic colitis-complex diarrhea (CCD). In order to reduce the need for antibiotics, a new and deeper understanding of the colonic microbial fermentation pattern in the pathogenesis of CCD is needed and how this fermentation can be modulated by dietary means to prevent or alleviate CCD.

    In this project we will characterize the microbial composition and fermentation pattern in feces from commercial pigs with and without CCD and use this knowledge to establish a new CCD experimental disease model in pigs. Finally, we will test the model and investigate if inclusion of high-amylose maize starch (HAMS) high in resistant starch and butyrylated HAMS can prevent or reduce CCD.

  38. SUPIAF - Sustainable protein ingredient for animal feed - GUDP project

    Mette Olaf Nielsen, Jan Værum Nørgaard, Ivan Lund, Jørgen Holm, Vegard Denstadli, Arne Ringsing, Ina Karlshøj, Michael Jensen & Eleni Nitojou

    Uniprotein is an environmental friendly bacterial protein source based on fermentation of natural gas. Uniprotein has a protein and oil content equivalent to fishmeal and contains other functional nutrients. The high content of zinc in the protein has been shown in pilot trials to have favorable effects on occurrence of diarrhea in piglets and potentially on intestinal passage rate and nutrient uptake in salmonids due to the content of nucleic acids and phospholipids. The protein has been approved by the EU as a feed ingredient, and the patented production process has within the last years been matured and up-scaled for possible commercialization. The objective of the project is to further develop the potential of the bacterial protein as a feed for weaner piglets and farmed fish. The product will be optimized in relation to nutrient requirements in the above-mentioned species, so that it can be utilized by feed manufacturing companies as a sustainable protein ingredient and a functional additive. Uniprotein will be tested at different dietary inclusion levels for functional response and digestibility in farmed animals, and for impact on the physical characteristics and quality of the feed. The product can contribute to an increased growth in aquaculture and pig production through better feed utilization and health, reduced CO2 imprint in feed production for livestock, minimized use of animal derived protein sources that are over-utilized and have limited availability (eg. fishmeal), diversified feed factories assortment, increased returns and improved health in productionDescription

  41. Development of a new model for partitioning excretion of nitrogen between urine and faeces in cattle production

    Peter Lund, Marianne Johansen, Martin Riis Weisbjerg, Mogens Vestergaard & Ole Aaes

    There is currently a strong focus on ammonia emissions from livestock production, partly as a result of demands for a national reduction of 24% by 2020. There is therefore a strong focus on correct estimation of emissions and the effect of any interventions. Correct distribution of the excretion of nitrogen (N) in faeces and urine, respectively, is absolutely essential for subsequent prediction of ammonia emission, as the emission can be attributed to a fixed proportion of inorganic N in urine as opposed to organically bound N in faeces, where emission is calculated as being zero. In the Danish standard normative system for livestock manure content of nutrients, the excretion of N in faeces is calculated on the basis of dry matter intake and N content in the diet, and excretion of N in urine is subsequently calculated as a difference. The equation for predicting the excretion of N in faeces (and thus N in urine) for dairy cows is based on data from digestibility experiments published in the period 1973-1996. This is data that is 20-40 years old and thus at a completely different production level than the modern dairy cow. When the equation today is used to predict the effect of e.g. increased milk yield and dry matter uptake, we therefore have to extrapolate far beyond the production level on which the equation is based. For young stock, the model is even based on data for a completely different animal, namely sheep on maintenance. This is not sustainable with the political and business focus that is on these data today.

  42. Diversification of the discard fish from Coastal Fisheries in the Belt Sea, through improved utilization of discard fish to high-value feed for Zoos, aquariums and pets

    Søren Krogh Jensen & Anne Krog Ingerslev

    The purpose is to diversify fishing in the Belt Sea through the use of discard fish for high-value feed for zoos, pets and aquariums. These fish include small herring and small bottom net mackerel; but also eelgrass, cuttlefish and other species that are currently without commercial interest.
    The secondary purpose is to create financial incentives for anglers to comply with the discard ban.
    The project include mapping of which discard fish are caught and in what quantities. Determine the nutritional composition and the nutritional value of fat, protein and minerals, as well as selling sample batches to the target groups in order to end up in an actual development of the sale.
    The project intend to show that economic sustainability can be created in the fisheries in the western Baltic Sea, which is currently hard hit by restrictions in the cod fishery and in the eel fishery by diversifying the fishery (use).

  44. Max 17% crude protein in the feed ration for dairy cows

    Marianne Johansen, Peter Lund & Dorte Niss Brask-Pedersen

    Projektets formål er at reducere køernes kvælstofudskillelse og øge restbeløbet pr. kg mælk ved at reducere proteintildelingen i køernes foderration uden samtidig reduktion i mælkeydelsen. Det søges opnået dels på kort sigt ved at reducere proteintildelingen i køernes foderration i besætninger, der fodrer med mere end 17 pct. råprotein i foderrationen, og dels på længere sigt ved at fremavle mere kvælstofeffektive malkekøer og ved dermed at kunne sænke proteinnormerne.
