圈养赤斑羚夏季日食量及表观消化率的探讨

<正>野生动物营养学是野生动物生态学和管理学的重要组成部分,是了解野生和圈养野生动物种群生存和繁殖的核心内容之一(Robbins,1983)。动物采食是一个复杂的、动态的、生物和非生物因素相互作用和相互影响的过程(Van Soest,1994),同时受动物自身、环境和饲料等多种因素的影响,有时还存在互作(NRC,1996)。采食量决定营养物质的摄入量,决定着动物能够从环境中获得营养物

The daily food intake and apparent digestibility by captive red gorals in summer

To analyze the daily feed intake and apparent digestibility to forage nutrition of red goral (Nemorhaedus cranbrooki) and determine diet composition,from June to August 2012,8 healthy adult red gorals from the Shanghai Zoo were selected and separated into 2 groups,group I and group II,based on different dietary roughage,to compare the daily food intake and apparent digestibility by red goral to different forages. The results showed that:(1)The average daily food intake of adult red gorals was (2801.44 ± 245. 02)g during the summer;(2)Male daily food intake (P <0. 05),apparent digestibility of crude fiber and apparent digestibility of dried matter and crude protein were significantly different between the two groups (P <0.05),and the difference in crude fat between the 2 groups was not significant. Red gorals showed preferences toward palatability of the Group II diet with higher daily intake and digestibility;therefore,Group II is the recommended diet for captive red gorals.
