Abstract

Abstract: Study was performed on effect of type of feed on excretion of fattening pigs and major pollutants it contains.Results show that compared with pigs fed with concentrate feed,pigs fed with concentrate-green combined feed excreted 18.97% less dung,and 38.56% less urine.After 50 d of feeding,pigs fed with concentrate feed gained on average only 1.5 kg more in weight than those fed with concentrate-green feed.The use of concentrate-green feed,however,saved cost of feeding by 21.68% per kilogram weight gain.It is,therefore,concluded that feeding pigs with concentrate-green combined feed can not only reduce pollution discharge,but also save feeding cost and raise pig-rearing efficiency.

Key words: pig, pollution discharge, feed, main contaminants
