动物园人工饲养蓝孔雀营养状况分析

Analyses of Nutritional Condition of Zoo Raised Blue Peafowl(Pavo cristatus)

以蓝孔雀为研究对象,用常规养分分析方法测定对其人工投喂食物中的粗蛋白(CP)、粗脂肪(EE)、粗灰分(Ash)、钙(Ca)和磷(P)等主要营养成分,参考营养需要量对其进行群体营养状况评价。结果表明:动物园提供的食物中蛋白质、钙、磷等养分均不能满足其在生长、繁殖、产蛋期的营养需要,动物园应适当调整孔雀在不同生理阶段、不同季节的营养配比,以改善孔雀的营养状况。

The nutritional condition of the zoo raised blue peafowl （ Pavo cristatus ） in Yunnan Wild Zoo was evaluated by regular laboratory nutrient determination of coarse protein （CP）, EE, Ash, calcium （Ca） and phos- phorous （P） contents out of the food artificially fed to the birds. The results showed that the protein, Ca and P nu- trition elements from the food supplied by the zoo were not sufficient to meet the nutritional demand of growth, de- velopment and reproduction stages of the birds. It was proposed that the nutrition ration of the blue peafowls in the zoo should be adjusted by different seasons and physiological phases to improve the healthy condition of the birds.
