Alternative Methods To Improve Livestock Performance While Grazing Low-Quality Forages., Ivan Raynard Thomas Jr

Graduate Theses and Dissertations

Stocker cattle producers in the southeastern part of the U.S. heavily depend on traditional forages such as bermudagrass [Cynodon dactylon] pastures during the warm season for grazing. Summer annual forages offer stocker cattle operations a valuable alternative source of forage. These forages have high yield potential and can help extend the grazing season. This is particularly beneficial during the summer months when traditional forage sources may be limited. Warm-season annual grasses may experience a decrease in crude protein concentrations during late summer and early fall. As a result, it may be necessary to find alternative sources of crude protein or …

Ontogenetic Variation In Palatal Morphology In Tufted And Untufted Capuchins, Valerie Contreras

Graduate Theses and Dissertations

ABSTRACT Craniofacial variation and its relation to diet have been widely examined, but with less attention exclusively to the palate. Previous studies have shown that groups consuming a more resistant diet exhibit morphological differences in the craniofacial skeleton, including a longer and wider palate when compared to groups consuming a less resistant diet; similar patterns have been observed among captive vs. wild populations. Here, I present a 3D morphometric analysis of palatal ontogeny in tufted (Sapajus spp.) and untufted (Cebus spp.) capuchins and compare captive vs. free-ranging semi-provisioned Sapajus. Tufted capuchins are known to consume more mechanically resistant foods compared …

Breaking Down Barriers To Giving: Policy Reform Needed To Protect Donors, Volunteers, And Food Charities, Ally Depriest

Journal of Food Law & Policy

Charitable organizations often depend on public support to fulfill their missions. This is especially true in the charitable food system, a network of nonprofit organizations, including food banks, pantries, and meal programs, which provide no-cost food to those in need. Within this system, volunteers, donors, and food charities each play an important role, such as donating surplus food, directing traffic at food drives, stocking local pantries, and preparing and serving meals at soup kitchens. Together, they provide both hope and nutrition to those in need. Without this public support, many food charities would be unable to operate. Encouraging public participation …

The Soil Crisis In Modern Food Systems: Rethinking Agricultural Land Use, Antonia Moure Richard

Journal of Food Law & Policy

Feeding a larger world while preserving the resource that makes agriculture possible—soil—poses a governance problem. By 2050, food systems must support 9.8 billion people even as prevailing practices continue to degrade soils that are non-renewable on human timescales. Technological fixes (e.g., vertical farming, hydroponics) may complement production, but they cannot substitute for soil at scale. The question that follows is simple: are current uses of soil compatible with the future needs of food systems? This article argues that without a shift in governance, short-run productivity gains are achieved by drawing down the soil asset, thereby undermining long-run food security and …
