中国本地肉用狗对日粮营养物质消化利用的研究

STUDY ON RATION NUTRIENT DIGESTIBILTIES OF CHINESE LOCAL DOG

选择本地肉用狗作试验动物,采用高、中、低质量不同的三种商品日粮作试验日粮,按全收粪法进行消化率的测定。试验结果,本地肉用狗对日粮营养物质的表观消化率分别是:干物质为83.48％,能量为85.76％,粗蛋白为85.8％,粗脂肪为89.26％,粗纤维为11.89％和无氮浸出物为69.29％。结果表明:三种日粮之间的干物质、粗蛋白、粗纤维和无氮浸出物等的消化率差异不显著(P>0.05),而A、B两组的能量和粗脂肪消化率显著高于C组(P<0.05),中国本地肉用狗对脂肪和蛋白质的消化率较高,而对植物性成份的碳水化合物(无氮浸出物和粗纤维)的消化率较低。

The digestable experiment was conducted with Chinese local dog and three kinds of different quality dog rations. The trial was conducted to gather all faces. The results showed that the apparent digestibities as follows- dry mater (DM) 83. 48%; gross energy (GE) 85.76%; crude protein (CP) 85.80%; ether extract (EE) 89.26%, crude fiber (CF) 11. 89% and nitrogen-free extract (NFE) 69. 26%.The difference of digesgtiblities of DM , CP, CF and NFE between 3 rations was not significant (P>0. 05). But the difference of GE and EE digestibilities was significant (P<0. 05) between ration A and ration C or ration B and ration C.
