The Swine Liquid Feeding Association annual research update provides progress reports on three projects they are currently working on. The first project, Emulsifiers for liquid feed involves various ingredient additives and processing techniques that can be used to increase the time it takes for corn to separate from the liquid it is suspended in. The second study Microbes for delivery of epidermal growth factor looks at the potential of additives to liquid feed to improve gut health and growth of weaner pigs. Epidermal growth factor (EGF) was added to feed along with lactococcus lactis (LL) which enhances the effect of EGF. There was proven growth when tested on mice and improved gut health in pigs. Currently when the diet was applied to pigs there was no improvement in growth. The third study Increasing nutritional value of co-products attempts to improve the digestibility of DDGS and wheat shorts by adding microbial inoculants and enzymes. The study has so far found that enzymes improve the nutrient release of DDGS, enzymes and microbial inoculants improve positive fermentation of steeped DDGS, and both additives improve body weight gain without compromising meat quality.
