Popis:	EPA in December, 2000 proposed rules that would bring more livestock operations under regulation and restrict manure application more closely to crop nutrient needs. This paper, using individual whole-farm modeling applied to survey data, assessed the impacts of the proposed regulation on hog farms in the Southern Seaboard region. Results showed impacts would be particularly severe on large-size farms (over 2,500 pigs) applying manure to Bermuda hay. Feeding hogs a phytase diet that reduces phosphorous in manure reduced the income loss for farms with limited acres for applying manure.
