The Danish dairy sector focus on reducing methane emissions from milk production before 2030. It is important that this is succeeded without compromising the milk quality. In our research projects, several feeding agents for methane reduction are tested e.g., 3-NOP and Nitrate, and the milk hereof is analysed with focus on vitamin, protein and lipid compositions.
Moreover, the use of fresh grass as cow feed has increased in Denmark due to new technologies and higher harvest yield. The use of fresh grass compared to silage has shown a comparable high yield in milk production and using locally produced fresh grass reduces the need for imported supplement protein, thereby reducing the carbon footprint. However, there is currently limited knowledge of the effects of using fresh grass as cow feed. Therefore, investigations of the milk quality from fresh grass-fed cows are needed to assess the use of fresh grass as cow feed in organic and conventional agriculture.
You will examine milk quality with for example GC-FID, HPLC, LC-MS, spectrophotometric assays, and use DCS, NMR, confocal laser microscope and Rheolaser for studying functionality of milk fractions.
The project is aligned to UN's SGD:
