Retrofit an optimized gestation stall system based on sow well-being: A pilot study
October 27, 2009By Janeen L. Salak-Johnson PhD
Sow housing has become a controversial welfare issue for pork producers. We cannot begin to implement costly alternative housing systems without scientific data that support these changes that could...

Effect of Adding Sawdust and Corn Stover on Thermochemical Conversion of Swine Manure into Crude Oil
September 2, 2009By Yuanhui Zhang
Our research team was able to produce bio-oil with blends of swine manure and cellulosic biomass. Laboratorial tests showed that adding cellulosic materials like sawdust and corn stover did not...

Ileal and total tract apparent and true digestibility of fat in distillers dried grains with solubles and other corn oil products fed to growing pigs
July 7, 2009By Hans Stein
The objective of this research was to test the hypothesis that oil in distillers dried grains with solubles (DDGS) and other co-products from the ethanol industry such as high protein distillers...

Immunogenicity and potency of PRRS MLV vaccines with and without interferon-alpha suppressing capacity
March 2, 2009By Federico A. Zuckermann
Interferon (IFN)-alpha is the most important anti-viral substance produced by mammalian cells in response to a viral infection. Accordingly, the production of IFN-alpha by an animal during a viral...

Net energy of three sources of distillers dried grains with solubles fed to growing and finishing pigs
February 5, 2009By Hans Stein
In North America, when energy is considered in formulation of swine diets, it is usually expressed as either digestible energy (DE) or metabolizable energy (ME). An energy system includes energy...

Impact of Auto-sort Systems on Pig Welfare
February 2, 2009By Janeen L. Salak-Johnson PhD
A series of studies were designed to determine any impact of various autosort layouts on pig productivity and welfare. To accomplish this, Exp 1, we compared food-court, fast-lane, and water-pen...

Critical review of literature on feeding bio-fuels co-products to pigs.
November 23, 2008By Hans Stein
The digestibility of nutrients in distillers co-products vary among sources. The variability is of the same magnitude as for other co-products. Heat damage to lysine often occurs, which results...

Digestibility of dietary fiber from distillers co-products fed to growing pigs
October 17, 2008By Hans Stein
The rapidly increasing production of ethanol is generating large amounts of distillers’ co-products that are available for swine feeding programs. These co-products can help reduce feed cost....

Development of improved trailer designs and transport management practices that create the optimum environment for market weight pigs during transport and minimize transport losses
October 9, 2008By Michael Ellis
The micro-environment experienced by pigs on the trailer during transport is critical for animal well-being and, potentially, impacts transport losses and, ultimately, pork quality. Environmental...

North American Swine Energy System, 2nd Year
September 30, 2008By James Pettigrew
Energy is the most expensive dietary essential in pig diets, but it receives much less attention in North America than is deserved by its importance. The digestible energy (DE) and metabolizable...
