Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2009, Katherine Mcgraw, Jennie Popp, Wayne Miller
Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2009, Katherine Mcgraw, Jennie Popp, Wayne Miller
Research Reports and Research Bulletins
This report is the sixth in a series of reports examining agriculture’s economic contribution on the Arkansas economy. Utilizing data from the United States Bureau of Economic Analysis (BEA), USDA Economic Research Service (ERS), USDA National Agricultural Statistics Service (NASS), and Minnesota IMPLAN Group, Inc. (MIG), the economic contribution of agriculture on the Arkansas economy was estimated for the most recent year available, 2009. Gross Domestic Product (GDP) by State information for Arkansas in 2009 was compared with those of other states in the southeast U.S. to give a measure of the relative importance of agriculture in Arkansas.2 The total …
Effects Of Tall Fescue And Lactate Dehydrogenase Genetic Polymorphisms On Dairy Heifer Growth And Immune Function, Rachel Henry, Marites Sales, Charles Rosenkrans
Effects Of Tall Fescue And Lactate Dehydrogenase Genetic Polymorphisms On Dairy Heifer Growth And Immune Function, Rachel Henry, Marites Sales, Charles Rosenkrans

Objectives of this project were to evaluate polymorphisms in upstream elements of the lactate dehydrogenase B (LDHB) gene in crossbred dairy heifers (n = 27) and their effects on immune function and heifer growth when grazing endophyte-infected tall fescue. Two cultivars of tall fescue were utilized: Kentucky 31 (KY31), a wild-type endophyte-infected tall fescue, and HiMag 4 (HiMag), a domesticated non-toxic endophyte-infected tall fescue. Crossbred dairy heifers (Holstein × Jersey) were stratified by weight and randomly allotted to forage. The LDHB gene codes for one subunit of lactate dehydrogenase (LDH), an enzyme that catalyzes pyruvate to lactate and back to …

Gene silencing is a process of suppressing activity of specific genes by producing “interfering” RNA encoded by foreign genes. This process serves as the principle of genetic modification in plants and animals, which is an important tool in genomics and biotechnology, allowing scientists to manipulate organisms to better meet human demands. New approaches of gene silencing may enable improvements on current practices of genetic modification, and broaden the application and impact of gene silencing in biotechnology. Recently, a novel vector design consisting of the transcription of short gene fragments lacking transcription termination signals was demonstrated to be effective in partial …
