熊用益胆素对无管取胆的熊胆粉产量与质量的影响

选用 9头胆汁产量稳定、体况相近的无管取胆黑熊 ,随机分成 3组添加含天然绿色饲料添加剂 0 .5 %组 (试验Ⅰ组 )和添加德国的PINA T饲料添加剂 0 .5 %组 (试验Ⅱ组 )及空白组 (对照组 )试验。结果表明 ,试验Ⅰ组胆汁产量、干粉率、干粉量有极显著提高 (P <0 .0 1) ,而试验Ⅱ组无显著提高 (P >0 .0 5 )。Ⅰ、Ⅱ组粗脂肪的消化率比对照组分别提高 2 .15 %和 4 4 .92 % (P >0 .0 5 )。熊胆粉分析结果表明 ,试验Ⅰ、Ⅱ组及对照组UDCA含量无显著差异 (P >0 .0 5 ) ,但高效液相色谱分析图谱中UDCA所占峰面积比例试验Ⅰ、Ⅱ组分别比对照组提高 2 9.6 5 %和 14 .6 2 % ,同时CDCA所占峰面积比例试验Ⅰ、Ⅱ组分别比对照组提高 34.5 0 %和7.0 9%。熊胆粉氨基酸分析结果表明 ,试验Ⅰ组和试验Ⅱ组及对照组氨基酸含量无显著差异 (P >0 .0 5 ) ;但试验Ⅰ组除天门冬氨基酸外其余均有提高 ,但差异不显著 ;试验II组各氨基酸含量均与对照组相近

Effect of Feed Additives on Production and Quality of Bile Powder Obtained with Tubeless Method from Black Bear

Nine black bears with similar live weight and yield of bile powder were randomly divided into 3 groups of 3 and fed a basal diet (control group), basal diet supplemented with 0.5% green feed additive (experimental group Ⅰ) and 0.5% German made feed additive PINA T (experimental group Ⅱ). The results showed that bile production, dry matter content of bile and bile powder production for group Ⅰ were significantly higher than those for control group ( P < 0.01 ), while there were no significant differences between group Ⅱ and control group ( P > 0.05). Crude fat digestibility for group Ⅰ and Ⅱ increased 2.15% and 44.92% compared with control group. Data of bile powder analysis showed that there were no significant differences in UDCA between groups ( P >0.05), while the pick areas of UDCA and CDCA in HPLC chromatogram for groups Ⅰ and Ⅱ increased 29.65% and 14.62%; and 34.50% and 7.09% compared with control group, respectively. Amino acid content of different groups did not differ significantly.
