Meta-analysis of swine manure and commercial fertilizer on environmental endpoints and soil health
Swine manure is a valuable asset when applied to the soil; however, to others it is a waste material with little value compared to commercial fertilizer. Comparisons between commercial fertilizer and swine manure are often difficult because of the conditions…
From feed to meat: investigation of the prevalence and distribution of Salmonella enterica serotype I 4,[5], 12:i: – a pathogen of interest in pork
Ensuring the safety of pork is essential for producers in order to maintain animal and human health, and also to continue serving export markets. One barrier to this is the rising occurrence of Salmonella contamination in pork. In order to…
Development of an interactive training app for timely and humane on-farm euthanasia in pre-weaned piglets
Euthanasia is a necessary act for any operation keeping live animals. However, science-based guidance for pig producers on proper on-farm decision criteria for euthanasia in piglets is deficient.
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…
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.
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…
