Exploitation of Ultrasound Technique for Enhancement of Microbial Metabolites ProductionMicrobial metabolites have significant impacts on our lives from providing valuable compounds for nutrition to agriculture and healthcare. Ever-growing demand for these natural compounds has led to the need for smart and efficient production techniques. Ultrasound is a multi-applicable technology widely exploited in a range of industries such as chemical, medical, biotechnological, pharmaceutical, and food processes. Depending on the type of ultrasound employed, it can be used to either monitor or drive fermentation processes. Ultrasonication can improve bioproduct productivity via intensifying the performance of living organisms. Controlled ultrasonication can influence the metabolites’ biosynthesis efficiency and growth rates by improvement of cell permeability as well as mass transfer and nutrient uptake rates through cell membranes. This review contains a summarized description about suitable microbial metabolites and the applications of ultrasound technique for enhancement of the production of these metabolites as well as the associated downstream processing.

Datafile: Estimated distribution of high nature value forest in the Republic of IrelandHigh Nature Value (HNV) farmland and forest systems play a vital role in supporting biodiversity and delivery of ecosystem services. Estimates of HNV forest area and distribution in the European Union (EU) are rarely conducted, despite having been a requirement of Rural Development Programmes. This work represents the first attempt to identify and estimate the area of HNV forest in the Republic of Ireland in a repeatable and transparent way. Relevant geo-datasets available for Ireland were collated and analysed. We investigated whether the datasets contained information on the indicators used in a recently-developed Nature Value (NV) index, and explored the potential of proxy indicators to determine the likelihood of a mapped area of forest being HNV. Based on these analyses, a likelihood map of the distribution of forest in different NV categories was produced and an accuracy assessment conducted. Results from this study suggest that HNV forest accounts for approximately 1 % of the Irish land area, or 8 % of the total forest area. Accuracy assessments indicated substantial agreement between the likelihood map classifications and the calculated NV status of National Forest Inventory plots. The methodology presented here could also be applied to existing similar datasets to estimate the extent and distribution of HNV forest in other regions. The mapped output provides a likelihood of a forest area being HNV and can provide evidence to inform the development of forest conservation policies.

Temporal trends in biosecurity in Irish pig herds using a standardized scoring systemAbstract Background Biosecurity measures are crucial to the introduction and spread of pathogens both within and between farms. External biosecurity focuses on preventing pathogens from entering or leaving the farm, while internal biosecurity aims to limit or stop the spread of pathogens within the farm. Implementing biosecurity measures not only protects animals from disease but also has positive effects on productivity, welfare and farm profitability. By reducing the need for antimicrobials, biosecurity measures also contribute to combating antimicrobial resistance. To assess and improve biosecurity, tools like Biocheck.UGent have been developed. In Ireland, the Biocheck.UGent tool has been widely used in pig farms since 2018. The aims of this study were firstly to assess temporal trends on biosecurity scores in Irish pig farms from 2018 to 2023 using the Biocheck.UGent tool and secondly to identify areas for improvement. Results There was an increase in the number of annual assessments over the study period, with the majority of farms being assessed multiple times. Overall, external biosecurity scores were higher than internal scores. Improvements in the scores were observed over time for most of the subcategories for external and internal biosecurity and across the different farm types. Analysis of the subcategories within the scoring system revealed areas with lower scores, including disease management, cleaning and disinfection, and measures between compartments. Weaner-to-finisher farms tended to have lower scores compared to other farm types. Conclusions While external biosecurity in Irish pig farms is generally high, there is room for improvement in internal biosecurity. This study highlights the importance of continuous efforts to improve biosecurity. The data obtained will aid in estimating the cost–benefit of implementing biosecurity measures, crucial for decision-making and better returns on investments.

Learning from Agricultural Land Market Regulation Policies in EU Member StatesThis article draws from economic theory and the recent European Commission report on agricultural land market regulation to assess the suitability of selected regulatory policies for agricultural land markets in Ireland. Insights from policy in other EU Member States indicates that some flexibility is always required to permit the existence of temporary land leasing contracts. Farmland rental prices in Ireland have mainly followed the underlying returns to agriculture and been much less influenced by speculative bubbles relative to farmland sales markets. The land rental data for 2019 do not point to the need for maximum price regulation. The availability of reliable statistics is not a sufficient condition to prevent bubbles from emerging, but farmland markets need to be closely monitored with up-to-date official statistics informing potential market participants and public policy.

Generational Renewal and Farm Succession: Insights from IrelandWe use Teagasc National Farm Survey (NFS) data to establish a better understanding about the age profile of people engaged in farming in Ireland and the related issue of farm succession. Insights are drawn from related research on the potential for farm partnerships to assist in improving generational renewal. The findings from the Teagasc NFS indicate a more complex relationship between economic performance and farm succession than is typically portrayed in the economic literature. The results indicate that in the non-dairy cattle system, the proportion of farm operators with an identified successor is lower for viable farms relative to non-viable farms and lower relative to viable farms in other farming systems. Cluster analysis of a sample of dairy farms indicates that the presence of young people in the household is just as important as farm economic viability in determining whether or not a farm successor is identified. The Teagasc NFS analysis indicates that many farms have young people contributing in terms of labour but delayed succession means fewer young farmers taking the role of farm manager. There is scope to increase the use of Farm Partnerships as pathways for younger farmers to progress from contributing labour on the farm to taking on a management role in the farm.
