About 200 dairy farms in Sweden use recycled manure solids (RMS) as bedding material and the number is increasing. Advantages is low price, reliable availability and good cow comfort. The main disadvantage is the risk of increased bacterial growth on the lying area affecting especially udder health and milk quality. The aim of the project is to develop the use of RMS and create guidelines. The project will analyze the effect of using RMS on milk quality and animal health using data from 40 dairy farms and Swedish experiences from RMS by depth interviews on the farms. Bacteriological analysis of RMS from the farms will determine hygienic quality. Furthermore, controlled investigations on the effect of RMS and different treatments (after digestion in biogas plant, hygienized, added with acids or lime) on hygienic quality and ammonia emission will be done. In addition, methane gas potential of the manure, environmental and economical considerations at farm level will be evaluated.
Cirka 200 mjölkgårdar i Sverige använder gödselfiber som strömedel och intresset för tekniken ökar. Fördelarna med fiberströ är priset, tillgången är säker och det ger en bra kokomfort. Nackdelen är risk för tillväxt av bakterier på liggplatsen som kan ge försämrad juverhälsa och dålig mjölkkvalitet. Målet med projektet är att utveckla och fastställa rekommendationer för användning av fiberströ. Projektet avser att undersöka effekt på mjölkkvalité och djurhälsa
genom analys av data i kokontrollen från 40 mjölkkogårdar samt samla svenska erfarenheter från fiberströ till mjölkkor genom djupintervjuer hos gårdarna. Bakteriologisk analys av fiberströ från gårdarna görs för att bedöma den hygieniska kvalitén. Lab-försök görs för att undersöka hur rötning, hygienisering, syra eller kalk påverkar hygienisk kvalité och ammoniakavgång. Provrötning görs för att undersöka effekten av gödselfiber på gödselns metanpotential. Dessutom genomförs en ekonomisk utvärdering av gödselfiber som strö.

It is well known that storage of animal manure and digestate causes emissions of methane (CH4), nitrous oxide (N2O) and ammonia (NH3). A crust on liquid manure acts both as a physical barrier for NH3 and as a biofilter that oxidize CH4 and NH3. However, N2O can be formed in some crusts, and there …
