摘要

This review explores the literature regarding the use of Recycled Manure Solids (RMS) as a bedding material for dairy cattle, in the UK. Recent papers, which used robust statistical analysis of data and were peer reviewed were accessed using commonly available search engines (Pub Med, Google Scholar and Science Direct). The effects of RMS use on cow welfare (particularly lameness and pressure lesions), milk hygiene, the environment and human health are explored. The practice of composting (whether intentional or inadvertent) to produce RMS is prohibited in the UK as the evidence for its benefits is not yet convincing and there are risks of increasing the growth of thermoduric organisms. There are benefits to cow welfare and comfort when RMS is used in cubicle housing. Some data regarding bacterial load and the risks to milk hygiene and human health are promising, in that RMS may be comparable with other bedding materials, but the issues of parlour routine and farm husbandry confound the effects of bacterial load in any chosen bedding. Research to date demonstrates that RMS may have a place in dairy cattle housing, but that the lack of studies, particularly those on a large scale, limits the data available and the ability to draw safe conclusions. There are significant uncertainties regarding associated risks to animal and human health from using recycled manure solids making it difficult to establish whether recycled solids can meet requirements and be deemed as safe to use. A structured review of literature highlighted that the management of the bedding material itself is more important especially regarding diseases and that there are substantial gaps within the research yet to be addressed.
