Pig waste is a problem for both farmers and the environment. Pigs are unable to digest phytate, a phosphorus compound that makes up 50 to 75 percent of the phosphorus content of the grains and plants eaten as dietary staples by these animals. The phytate is then excreted in the pig waste, contaminating agricultural areas via run-off and drainage, sometimes resulting in fish kills. In addition, the pigs require supplementation. Researchers at the University of Guelph have attempted to find a solution to these problems – and they’re calling it
Enviropig.
