Effects of inclusion of corn distillers dried grains with solubles in the diet of finishing pigs and gestating sows on nutrient excretion and gaseous emissions
Three experiments were conducted to determine the effects of DDGS on nutrient excretion and gaseous emissions by swine. In Exp. 1, a total of 80 pigs initially weighing 36.8 kg were blocked by...

Comparison of efficacy, emissions, compost characteristics, and costs of in-vessel rotating drum and open static pile composting of swine carcasses, whole and ground.
In the U.S. the use of composting to manage on-farm swine mortality has increased from 10.5 to 35.9% from 1994 to 2006 (USDA:APHIS, VS, CEAH 2001 and 2007). Very little is known about the emissions...
