| 摘 要： | 试验选用 3只 15月龄的非洲鸵鸟 (1公 2母 ) ,采用全收粪法对鸵鸟表观消化率进行了测定。其测定结果为 :干物质 5 5 .9%± 0 .2 1% ,粗蛋白 6 8.5 %± 0 .2 2 % ,粗纤维 5 7.4 %± 1.2 1% ,粗脂肪 5 8.8%± 1.35 % ,无氮浸出物 75 .3%± 0 .6 2 % ,总磷 5 5 .2 %± 1.10 %。钙消化率因消化道中存留较多的沙石而未能测得。同时探讨了鸵鸟消化率测定的适宜方法

| Abstract: | Three 15 months age ostriches(1♂2♀)were used to determined apparent digestibility of nutrients in this experiment. The result showed that apparent digestibility of DM ,CP, CF, EE, NFE and total P were 55.9%±0.21%, 68.5%±0.22%, 57.4%±1.21%, 58.8%±1.35%, 75.3%± 0.62% and 55.2±1.10% respectively. The digestibility of Ca was not measured because there was lots of sand in alimentary tract. The proper determination method of digestibility in ostrich was discussed as well. |
