Animal and Food Sciences Faculty Publications

Selenium (Se)-deficient soils necessitate supplementation of this mineral to the diet of forage-grazing cattle. Functionally, Se is incorporated into selenoproteins, some of which function as important antioxidants. We have previously shown that the source of supplemental Se; inorganic (sodium selenite or sodium selenate; ISe), organic (selenomethionine or selenocysteine; OSe) or 1:1 mix of ISe and OSe (MIX), provided to Angus-cross cows affects concentrations of progesterone (P4) during the early luteal phase of the estrous cycle. In this study, we sought to investigate (1) the effect of form of Se on the expression of mRNA encoding selenoproteins in the corpus luteum …

Cultural Sensitivity: A Requirement When Developing Food Safety Interventions, Lillian Nabwiire, Angela M. Shaw, Gail R. Nonnecke, David D. Minner, Ellen Johnsen, Louis E. Petersen Jr

Journal of Extension

Extension materials that are sensitive to changing demographics and culture increase relevance and compliance with food safety practices. Produce safety extension materials were developed for U.S. Virgin Islands (USVI) produce growers to help with compliance with a new food safety rule. We developed employee training materials based on a needs assessment and behavioral change was evaluated six months after dissemination. The original materials were not seen as culturally appropriate but after modifications, improvements in food safety practices and behavior changes were observed. These results suggest that extension educators should seek feedback from target populations about potential interventions before implementation.
