Polyphenol Characterization And Antioxidant Capacity Of Multi-Species Swards Grown In Ireland—Environmental Sustainability And Nutraceutical Potential, Samuel Rapisarda, Nissreen Abu-Ghannam

Articles

Ruminant production systems are major contributors to greenhouse gases emissions, with animal feeding practices being the main cause for methane and nitrous oxide’s release. Although feeding animals forages has been proven to be more sustainable, traditional ryegrass monocultures still require a lot of input (e.g., fertilisers and pesticides). Multi-species swards, consisting of different swards, such as grasses, forage legumes and herbs, need less management and fertiliser, produce more dry matter, and also add a variety of phytochemicals into the animal diet. In particular, polyphenols have been associated with a positive impact on animal health and productivity. However, data on the …

Zoned Leasing Impact On Shellfish Aquaculture Industry Development, Rebekah Woodburn

All Theses And Dissertations

Shellfish aquaculture is a growing industry in the United States that supports many individuals and communities. An important step in establishing or growing a shellfish aquaculture operation is obtaining a lease in which to cultivate shellfish. While many states allow aquaculturists to find their own lease location, the often time-intensive and expensive process to have the lease approved and permitted can be a great barrier for new entrants to the industry. Zoned leasing is a way for state agencies to establish large areas and pre-approve them for shellfish aquaculture, then divide the areas into smaller parcels of leases to be …
