| Ammonia emissions from barns have a severe impact on the environment. Especially dairy cattle, kept in loose housing, contribute to the total emission of ammonia up to 50%. Soiled walking areas like slatted floors, are realised as one of the main sources of the emission. In this study, a special cleaning device was used in order to remove manure from a slatted floor in an organically run dairy barn. It was investigated how the combination of a rubber-scraper, mechanical star discharge rotors and high-pressure water nozzles affects the ammonia emission from the floor. Six concrete test elements (55cm x 62cm x 20cm) were cut out of the existing slatted floor in order to be able to separate them from other sources of ammonia emission in the barn. With a... |

| Consumer trust in the food industry is heavily reliant upon accurate labelling of meat products. As such, methods which can verify whether meat is correctly labelled are of great value to producers, retailers, and consumers. This paper illustrates two approaches to classify between, fresh and frozen thawed, and in a novel manner matured and matured frozen-thawed, as well as fresh and matured beef using the 500-1010 nm waveband, captured using hyperspectral imaging, and CIELAB measurements. The results show successful classification based upon CIELAB between 1) fresh and frozen-thawed (CCR = 0.93), and 2) fresh and matured (CCR = 0.92). With successful classification between matured and matured frozen-thawed beef using the entire spectral range (CCR =... |
