| 中文摘要: |
| 通过饲喂自然种子及人工饲料块等单宁和皂苷含量不同的食物,研究了食物中单宁或皂苷水平对小白鼠(Mus musculus domesticus)食物选择的影响,以及取食经历在其食物选择中的作用。结果表明,(1)无论有无取食经历,小白鼠均优先取食次生物质含量低的锥栗(Castanea henryi)或花生(Arachis hypogaea),而很少取食单宁含量高的栓皮栎(Quercus variabilis)或皂苷含量高的油茶(Camelia oleifera);(2)小白鼠的取食经历能增强其对种子中单宁或皂苷水平的识别,从而减少其摄入;(3)小白鼠的食物摄入量随单宁或皂苷含量的增加而显著降低。本研究说明单宁或皂苷均可显著影响动物的食物选择,且取食经历能增强动物对食物的识别能力。 |

| We tested the effects of food tannin and saponin on diet selection of mice(Mus musculus domesticus) by using natural seeds and artificial food with different amount of tannin or saponin.We also investigated the effects of feeding experiences on diet selection.The results showed that:(1) regardless of feeding experiences,mice preferred to consume more seeds with lower tannin(i.e.Castanea henryi) or saponin(i.e.Arachis hypogaea) over those with high tannin(i.e.Quercus variabilis) or saponin(i.e.Camelia oleifera);(2) feeding experiences for mice could enhance its ability to identify tannin or saponin levels in seeds,resulting in less food intake;and(3) food intake of mice significantly decreased with the increase of food tannin or saponin level.Our study indicates that food tannin or saponin can highly influence food selection by animals and feeding experiences can promote the animals to identify and use different kinds of food. |
