昆明动物园笼养倭蜂猴的能量代谢

食物是动物适应性生存的基础,能量平衡对动物生存、繁殖和进化起着至关重要的作用 (McNab,1988).

Energy metabolism of Pygmy loris(Nycticebus pygmaeus)in cage of Kunming Zoo

The Pygmy loris (Nycticebus pygmaeus) is a small prosimian living in Vietnam, Laos, eastern Cambodia and the south of part China. In China it is only found in Pingbian, Hekou, Jinping, Luchun of Yunnan Province. As yV. pyg-maeus is seriously threatened by hunting, trade and habitat destruction, it is listed in Appendix II of CITES, and in 2006 the IUCN classified it as " vulnerable". But the Pygmy loris is nocturnal which creates difficulties to study in the field. In order to understand the characteristics of energy metabolism in N. pygmaeus, the energy intake, digestable energy intake and digestability were estimated by means of feeding trials in Kunming Zoo. The results obtained mainly were as follows: N. pygmaeus intook dry food averaged 9. 28±0. 48 g per day. Therefore they were estimated to gain 160. 94 ± 8. 05 kJ/d from food intake, and earn 34. 00 ±7. 74 kJ digestable energy intake per day with 82. 84± 1. 98% of the digestability. All these characteristics of energy metabolism in N. pygmaeus of cage are possibly related with their body mass, climate, habi-tat , and might be considered as the adaptive characteristics to their survival environment in tropical semi-evergreen and sec-ondary forests.
