University of Guam conducts study into pig waste effects

Scientists from the University of Guam say a study shows that imported pig feed affects the run-off which in turn creates algae blooms and damages the coral reef.

A grant from the US department of agriculture allowed the university to conduct a study of the varying types of feed for the pigs, the resulting growth rates and the levels of nutrients.

Manuel Duguies of the University of Guam says the study shows that a reduction of commercial feed would lower both the cost of raising pigs, and the high levels of nutrients in pig refuse.

He wants to perform feeding demonstrations for Guam's farmers to show them the benefit of change.
