Effect of Diet Composition and Particle Size on Nutrient Excretion of Finishing Pigs and Propensity to Cause Manure Pit Foaming
Fibre composition in soybean hulls has a greater impact on manure-foaming capability than the fibre in DDGS, report Zhaohui Luo, Pedro Urriola, Bo Hu, and Gerald Shurson of the University of Minnesota and Brian Kerr of USDA-ARS. They also found that diets of larger particle size increased the manure-foaming capability of the feed.
