日粮中苹果添加量对圈养小熊猫健康的影响OA北大核心CSTPCD

This study was to investigate the effects of supplemented apple levels on the health of red panda.Two groups of apple content di-ets were set up(low apple diet for phaseⅠ,high apple diet for phaseⅡ)to investigate the effects of the diets on the intake and excretion of nutrients,apparent digestibility and physiological parameters of the pandas.Each phase lasted 20 days,for a total of 40 days.The results showed that the total feed intake and dry matter output of the red pandas in in phaseⅡ(high apple content)of the investigation were signifi-cantly higher than those in phase Ⅰ(low apple content)(P＜0.01),while the mean feed intake,fecal output,dry matter intake and dry matter digestibility of bamboo leaves of the animals were not significantly different between the two phases(P＞0.05).There were no signifi-cant differences in their body weight and blood physiology indexes between the two phases(P＞0.05).The hematological indexes of fruc-tosamine and blood potassium of the pandas at the end of phaseⅡwere significantly higher than those at the end of phaseⅠ(P＜0.05);the urea nitrogen was significantly lower than that at the end of phaseⅠ(P＜0.05),and the total bilirubin and blood amylase were highly signif-icantly higher than those at the end of phaseⅠ(P＜0.01).In summary,all the variables were within the normal range except urea nitrogen,which was slightly higher.Both feed formulations of the two phases provided balanced nutrition,but the amount of apples in the feed should be controlled,and the feed amount should be adjusted according to environmental changes for and the growth of the pandas.At the same time,weight monitoring and physical examination for the animals should be regularly performed.
