Technical Summary
This sub-programme investigates how forage chemistry and post-harvest changes of fresh forage affect ruminal fermentation, and the extent of genetic control. Transcriptomic and proteomic approaches together with bio-imaging and unbiased and targeted metabolite analyses of established in vitro and in sacco experimentation will be used to identify the key plant-based traits that can influence the rumen systems model. Candidate post-harvest responses for targetted analysis include control of plant-mediated proteolysis during rumen-induced plant cell death, microbial molecular pattern recognition, drought/ flooding responses and wound responses. Appropriate germplasm will be sourced and used in functional hypothesis testing. Forage characterisation will be performed by use of chemometrics (FTIR, Micro RAMAN, GC-MS, LC-MS) with multivariate data analysis to understand inputs delivered by the feed and the extent of its genetic control. High throughput screens under development will enable assessment of methanogenic properties of large numbers of forage genotypes. This will exploit the extensive genetic resources at IBERS, for example, ~14,000 populations of the forage grass Lolium perenne. The combination of high throughput screening and genetic variation of defined pedigree presents the opportunity to develop and use machine learning approaches such as genetic algorithms (GA) to streamline screening and selection by operating a virtual evolution.

| Description | 1. This work has lead to an increased understanding of control of plant metabolism in ingested forage. We have demonstrated similarities in post-harvest plant cellular response with systems known to be involved in stress tolerance and pathogen resistance in the field. These responses, and more recently exposure to stress events prior to ingestion have been shown by metabolomic and proteomic techniques to alter the functioning of the rumen microbial population. 2. Specific attention has been given to understanding the plant's role in delivery improved protein supply. We have used proteomics to identify specific protein targets for rapid proteolysis which is key to this inefficiency. These are largely chloroplast located and have in consequence identified the potential for the polyphenol oxidase enzyme to protect through phenolic complexing. We have extended studies with Festulolium grass hybrids to use a continuous flow rumen simulator (animal mimic system) to confirm indications from previous in vitro studies that whole genome hybrids can deliver better protein supply kinetics than a standard ryegrass sward. This has been published. |
| Exploitation Route | The aim of this work was to identify traits that to be taken forward by breeders for improved animal efficiency. We have shown that changes in forage genotype leading to subtle changes in phenotype can have significant implications for ruminal fermentation. The correspondence of response to systems where there is much existing work (eg pathogenesis) opens up potential for further research to exploit synteny with known genetic mechanisms in improved forage germplasm. The potential for development of festulolium hybrids in the context of an improved forage for grazing should next be established in a grazing trial. After this social and economic impact could be realised in a relatively short time. Hybrids are commercially available (eg AberNiche) and exisiting links with Germinal Holdings would facilitate up-scaling and commercialisation. |

| Description | Findings have been used in outreach activities at Royal Welsh Show and School Science Week to engage with farming community, general public and children. This involved hands-on experiences including viewing rumen micro-organisms under microscope and extracting DNA. Our research is also contributing to discussions as part of networks in South America and Africa in relation to sustainability and food security (via GCRF-IAA #BB/GCRF-IAA/09). This has raised awareness of our plant improvement activities to in-country organisations that can disseminate information to the appropriate communities for uptake of either materials or practice as required and appropriate. |

| Results and Impact | With British producers facing ever-increasing expectations - to deliver traceability, meet higher environmental standards and maintain the countryside - Waitrose, IBERS and suppliers have been working together to share experiences on topics such as animal and plant diseases, food security issues and strains on productivity. This event gave suppliers, large and small, direct access to Waitrose buyers, food technologists and scientists and helped smaller producers, in particular, to understand food legislation. The outcome of the event was a sharing of best practice throughout Waitrose's supply chain and beyond. |
