Manure Value Exceeds Expectations: New study reveals hog manure boosts crude protein in forages as well as improves yields

摘要

Pork producers nave long known that hog manure is a great substitute for commercial fertilizer in crop production. A new study at the University of Manitoba shows that applying hog manure on tame grass hay land and pastures is also a great way to increase forage yield and quality. The three-year study found that forages treated with hog manure had up to 80% more crude protein than untreated fields, a surprisingly high advantage, says head researcher Kim Ominski, associate professor at the university's Department of Animal Science.
