Background: Oxidative damage in feedstuffs represents a significant economic loss because it negatively affects pig health and growth performance. Lipid peroxidation occurs during the production of corn dried distillers grains with solubles (DDGS). Corn oil, which is typically present at…
Interactive effects of distillers dried grains with solubles (DDGS) and housing system on sow performance and longevity
Background: Use of DDGS in diets for growing swine has been the focus of much research effort in the past 5 – 7 years with little attention paid to DDGS use in diets for breeding females. In fact, sows are…
PRRSV Modulation of the Porcine Antibody Repertoire
Antibody responses play a crucial role in defense against many viral diseases, and knowledge of critical functions can be used to monitor and predict vaccine efficacy. We have identified the features of key antibodies produced in response to PRRSV, and…
Structural characterization of the PRRSv glycan shield
Knowing the composition and structure of PRRSV is an important prerequisite for development of immunological prevention and control strategies, just as knowing what a spark plug looks like is important when you need to replace it. The surface of a…
Assessment of the effects of diets containing DDGS with supplemental tallow on fat digestibility, growth performance, carcass and fat quality in growing-finishing pigs
The use of dried distillers grains with solubles (DDGS) in swine diets has increased dramatically in recent years due to the increased availability and cost competitiveness of this corn co-product compared to corn and soybean meal. Due to high ingredient…
Characterization of Mycoplasma hyorhinis transmission and spread within endemically infected populations
Bacterial diseases create a significant economic impact in today’s swine industry by causing an increase in mortality rates and a reduction in feed efficiency and growth. Polyserositis is one of the main causes of mortality in nursery pigs. The bacterium…
Application of FTA based technology for the collection and transport of clinical samples to detect PRRSV by RT-PCR
The ability for producers to succeed depends in part, on their ability to rapidly respond to emerging and existing disease challenges. Submission of fresh samples to diagnostic laboratories in a timely manner often represents a challenge. The use of FTA…
An assessment of air filtration for reducing the risk of PRRSV infection in large breeding herds in swine dense regions
As the US swine industry moves towards regional control and elimination of PRRSV, a critical component is the ability to reduce the risk of the airborne spread of the virus between herds. Therefore,the filtering of incoming air to has been…
Survival of porcine reproductive and respiratory virus and porcine circovirus on pork and pork products
The introduction of animal diseases through import/export of pork and pork products is a major concern for the swine industry. Trade restrictions have been imposed by several countries on uncooked meat and meat products of pigs because of the possibility…
Effect of a softer floor surface in the farrowing crate on the expression of lameness and subsequent sow performance
The aim of this study was to explore the effect of providing rubber mats in farrowing crates on the impact of lameness on sow welfare and performance. The study was conducted at Southern Research and Outreach Center, Waseca and involved…
