The digestibility variations of energy, protein and other nutrient components in feed which had been mixed with natural compound mineral was determined via throughout a digestive trial by using 6 growing boars from the progenies of 3-strain hybridization.The feed was labelled by Cr2O3 to monitor its passing duration through the digestive channel.The results showed that,the digestibility of crude protein of trial group increased 5.82 percentage(79.50%vs。 73.68%,P0.05):the digestibilities of general energy.crude fibre and Ca increased 1.44 percentage (71.25%vs.69.81%),0.56 percentage(40.09%vs.39.53%)and 1.11 percentage(47.48% vs.46.37%)respectively(p0.05):the digestibility of P decreased 1.13 percentage(54.81% vs.55.94%.P0.05) to compare with control group.The duration when feed passed through di-gestive channel of trial group was averagely 23 minutes Ionger than that of control group.
