Eight-month-old Wulong geese were fed with the diet with different proportions of Leymus chiesensis at the same energy and protein level.The activities of plasma Alkaline Phosphatase(AKP),Acid Phosphatase(ACP),Choline Esterace (CHE),Lactic Dehydrogenase(LDH),Glutamicoxalacetic Transaminase(GOT)and Glutamatepyruvate Transaminase(GPT) were determined and then their correlations with fiber digestibility and the apparent digestibility of Ca,P,Met and Cys were analyzed.The results showed that the activity of AKP took on a significant downtrend as the increasing of Leymus chinensis proportion(P<0.05).There was a negative correlation between the AKP activity and the digestibility of crude fiber(CF),neutral detergent fiber(NDF)and acid detergent fiber(ADF)(P<0.05).However,there was a significant positive correlation between the AKP activity and the apparent digestibility of Ca,Met and Cys(P<0.05).Moreover,the activities of the other five enzymes had no significant correlation with the digestibility of CF,NDF,ADF,and the apparent digestibility of Ca,Met and Cys(P>0.05).
