Effects of body weight and research conditions on the determination of the productive energy content of corn germ meal fed to growing-finishing pigs.
Corn germ meal (CGM), a co-product of the corn wet milling industry, is an ingredient that could be used to reduce the cost of swine diets. Efficient use of any ingredient requires an accurate estimate of energy content and metabolizable…
Broadly protective nasal mucosal vaccine for influenza A virus of swine
Influenza A virus of swine (IAV-S) is widespread and causes significant losses to swine producers. Besides its economic burden, the virus also poses a great threat to public health due to its zoonotic potential. Therefore, successful control of IAV-S will…
Assessing the role of medium chain fatty acids as an alternative to medically important antibiotic
Research has demonstrated that medium chain fatty acids (MCFA) can serve as reduction strategies for bacterial and viral pathogens in animal feed and ingredients. However, it is unknown how the type or level of MCFA impact bacteria growt
Impact of host immunity and genetics on persistence of PRRS virus in tonsils
Despite extensive efforts to eliminate PRRS from US production facilities, it remains a key disease issue and poses a continued economic threat to the industry, particularly in pig dense areas.
Evaluating the effects of mitigation strategies on piglet welfare and future productivity after transport during different seasons
As consumer concern for swine welfare, husbandry methods, and antibiotic use in animal agriculture increase, so will the need for U.S. pork producers to demonstrate that current production practices not only increase animal performance, but also improve the overall health…
Enhancing growth performance in pigs by treating with iron at weaning and feeding antibiotic-free nursery diets containing elevated concentrations of copper or zinc
Addition of copper sulfate or zinc oxide to nursery pig diets at levels in excess of dietary requirements was previously shown to enhance growth performance.
Development and Validation of Novel Diagnostic Assays and Investigation of Disease Pathogenesis for Infectious Arthritis in Growing Pigs
Formerly a "fringe" issue, lameness in swine production has become a priority in the face of recent veterinary and producer-driven lameness investigations showing that losses attributable to lameness can reach $23 per growing pig, and culls or mortality due to…
Genome wide identification and annotation of functional regulatory regions in livestock species
The objectives of this study were to identify previously unknown regions in the pig genome that act to regulate genes, and therefore play a role in the traits the pigs exhibit.
Detection and differentiation of field strains and commonly used vaccine strains of Type 2 PRRS virus in the US
PRRS remains the most economically devastating swine disease with an estimated annual loss of $664 million in the US. The PRRS genome is constantly changing, making accurate diagnosis difficult. Many pairs of primers have been used in some commercial PRRS…
Estimating the National Prevalence of Salmonella spp. In Lymph Nodes from Market Hogs and Sows
The goal of this study was to determine the prevalence of Salmonella enterica in lymph nodes in sows and market hogs.
