Research report: Effect of Sal-CURB® on digestibility of energy, amino acids, calcium, and phosphorus in growing pigs

Porcine epidemic diarrhea virus (PEDV) can be spread via contaminated feed. Treating PEDV-contaminated feed with formaldehyde has been shown to prevent infection in pigs that consume the feed. However, concerns have been raised about the effect of treatment with formaldehyde on the nutritional value of feedstuffs. Therefore, an experiment was conducted to determine the effects of adding a formaldehyde-based feed disinfectant to the diet on the apparent ileal digestibility (AID) of dry matter, crude protein, and amino acids, and the apparent total tract digestibility (ATTD) of dry matter, gross energy (GE), calcium, and phosphorus in nursery pigs.

Podcast: Effect of particle size of calcium carbonate on apparent and standardized total tract digestibility and retention of calcium by growing pigs

Laura Merriman, a Ph. D. student in the Stein Monogastric Nutrition Lab, present the results of her research on the effect of particle size of calcium carbonate on digestibility and retention of calcium and phosphorus by growing pigs.

Press release: Pigs gain the same with corn-ethanol co-product as with corn-soybean meal diet, says study

URBANA, Ill. - Distillers dried grains with solubles, or DDGS, are increasingly common in swine diets in the United States. In recent years, different types of DDGS have come on the market.

"Ethanol plants use different procedures to produce DDGS, which results in different end products," said Hans H. Stein, a professor of animal sciences at University of Illinois.

"To produce conventional DDGS, the corn is cooked to gelatinize starch prior to fermentation. However, uncooked DDGS can also be used if specific enzymes are used to pre-digest the starch prior to fermentation. Some ethanol plants also use a different fractionation technology to produce DDGS with more protein than conventional DDGS."
