Item Five-year old diversified pasture supports greater lamb liveweight gain than a standard perennial ryegrass-white clover pasture(New Zealand Grassland Association, 2023-03-01)This study investigated liveweight gain of lambs grazing five-year-old pasture of either Italian ryegrass, red clover and plantain (Diversified) or perennial ryegrass and white clover (Standard). Coopworth lambs were born to either diversified or standard pasture and reared there until weaning in December (early summer). Liveweight gain (LWG) from tailing to weaning was 23% higher in lambs on diversified pasture (0.335 kg LWG/lamb/day) compared to those on standard pasture (0.272 kg LWG/lamb/day). From summer to autumn (December to May), liveweight, pasture mass, botanical composition and nutritive quality was measured as weaned lambs progressed through rotationally grazed paddocks of either diversified or standard pasture. Similar lamb liveweight gain between pasture types was observed over summer and autumn, with both groups averaging 0.187 kg LWG/lamb/day. From December to May, dry matter intakes (DMI) and feed conversion efficiencies (FCE) were similar between lambs grazing on either diversified or standard pasture. Average final lamb liveweight off diversified pasture was 4.2 kg higher than off standard pasture. The higher pre-weaning liveweight gain and subsequent greater weaning liveweight off diversified pasture was maintained throughout the summer and autumn.Item Linking farmers to markets: Barriers, solutions, and policy options(Elsevier on behalf of Economic Society of Australia, Queensland, 2024-06)The 15 studies highlighted in this special issue collectively underscore the significant impacts of market participation on farmers’ well-being, income, poverty reduction, dietary diversity, and rural economic growth. They also delve into the importance of marketing channel choice and the role of e-commerce in enhancing farmers’ market linkages. In addition, they address farmers’ preferences for market access interventions and the examination of market power within the agricultural industry, especially in low-income countries. The key findings include: (1) Market participation is critical for improving farmers’ subjective and objective well-being, with studies demonstrating positive impacts on income, poverty reduction, and dietary diversity; (2) The choice of marketing channels significantly influences income, with evidence suggesting online sales can substantially increase farmers’ earnings; (3) E-commerce plays a pivotal role in connecting farmers to broader markets, leading to income growth and enhanced market visibility; (4) Understanding and addressing farmers’ preferences for market access through interventions like systematization policies and joint ventures can facilitate better market integration and support inclusive business models; (5) Analysis of market power within the primary foods industry reveals rising markups, particularly affecting low-income countries. These findings suggest that policies and interventions aiming to improve market access, promote e-commerce, and consider farmers’ preferences and market power dynamics can significantly impact farmers’ incomes, poverty levels, and overall rural economic development.Item Fostering resilience: Converging UNSDG 17 and future foresight collaborations(2023-11-09)The envisioned session seeks to equip participants with the means to apply a stakeholder ecosystem perspective, leading to the establishment of partnerships that foster SDGs and nurture global resilience for the future. This endeavour aligns seamlessly with the overarching concept of 'Promoting Resilience on the Rim by Using the Sustainable Development Goals.'Item Understanding the dynamics of psychological ownership and community embeddedness in family businesses: A case study Barker’s of Geraldine(2023-12-06)Family businesses are crucial in rural communities primarily due to their strong community embeddedness. However, existing literature lacks an in-depth understanding of the motivations and drivers behind this community embeddedness. This study explored the interconnections between psychological ownership, community embeddedness, and family businesses in rural communities and examined their practical implications. This study fills this gap by conducting an exploratory case study of Barker's of Geraldine, contributing to the literature by highlighting psychological ownership as a key motivation and driver for community embeddedness in family businesses. This research provides practical insights that guide policy and economic development initiatives in rural areas by investigating the link between psychological ownership and community embeddedness in rural family businesses.Item Nutrifermentics: Pioneering next generation fermented products(2023-11-20)Nutrifermentics” is a new concept we have developed to describe an approach to fermentation focused on understanding how specific dietary compounds impact on the epigenetic regulation of microbial strains. We use this knowledge to develop microbial strains for food and beverage production without resorting to genetic modification. Our innovative approach, rooted in epigenetics, allows us to modify the metabolomic profile of fermented products without directly altering the DNA of the involved microbes. This cutting-edge technique has already shown promising results in alcohol fermentation and wine production. Here, we investigated the epigenetic responses (changes in DNA methylation levels) of the probiotic gut bacteria Lactobacillus acidophilus, which is widely used in yogurt making, to dietary epigenetically-active compounds such as genistein. These epigenetic changes altered the metabolomic profile and produced beneficial primary and secondary metabolites, including antimicrobial compounds like 3-phenyllactic acid and health-promoting substances like trehalose. Moreover, this study demonstrated that individual genes or loci, such as those responsible for melibiose production which was upregulated 8 fold, can be altered without resorting to genetic modification methods such as CRISPR, thus highlighting the plethora of biotechnology applications for this technology. This in-depth multiomic analysis of the effect of certain dietary compounds on epigenetics, transcriptomics, and metabolomics in the probiotic gut bacteria Lactobacillus acidophilus, provides useful insights into the role of dietary compounds on the fermentative capability of bacteria. Furthermore, this study has shown that dietary epigenetic compounds can be used to alter the microbes used in the fermentation process, ultimately leading to the development of sustainable and non-GMO fermented products.
