The impact of brassica (such as rape, kale, turnip, swedes) on methane emissions in sheep were investigated in two PGgRc-SLMACC-funded trials. Changes in the microbial communities of sheep in these trials were investigated as part of the PGgRc programme (‘microbial ecology’ in support of ‘low greenhouse gas feeds’). The data from these trials are being prepared for publication. The sequencing data need to deposited in publicly available resources for gene sequences (e.g. NCBI or EBI) prior to publication. This is a common policy for international peer-reviewed journals and the process of data deposition can take several months. Due to the duration of this process and in order not to delay publication, Peter Janssen and Mark Aspin discussed the deposition of the data from the aforementioned trials prior to publication and agreed that the data can be submitted in advanced. This ROI serves to formalise this process.
