Composting Livestock Waste Provides Benefits
...o large livestock producer: The total volume is reduced
by as much as 80 percent, which results in less hauling and spreading. "Composting offers a more efficient use of labor, which is a considerable cost savings," Hawkins says. The composting does not attract flies and other insects as manure does. ...
Mice Lacking The Pax8 Gene Suffer From Hypothyroidism And Fail To FormThyroxin-Producing Cells Of The Thyroid Gland
