ABSTRACT

1. The purpose of the present study was to examine whether zymosan, which is a component of fungi, affects feed passage through the digestive tract in chicks (Gallus gallus).

2. Intraperitoneal (IP) injection of 2.5 mg zymosan significantly reduced the crop-emptying rate and this effect was similar to that of 100 µg lipopolysaccharide (LPS). Zymosan affected phenol red transit from the proventriculus.

3. Zymosan significantly affected the gene expression of interleukin-1β (IL-1β), IL-6, IL-8 and histidine decarboxylase in various regions of the digestive tract.

4. The present study suggested that zymosan retarded feed passage through the digestive tract in chick and interleukins and histamine may be participating in this process.

摘要

1.本研究的目的是检查作为真菌成分的酵母聚糖是否会影响雏鸡（鸡胆）通过消化道的饲料通过。

2.腹膜内（IP）注射2.5 mg酵母聚糖显着降低了作物的排空率，该效果与100 µg脂多糖（LPS）相似。酵母聚糖影响了来自前列腺的酚红转运。

3.酵母聚糖显着影响白细胞介素-1β（IL-1β），IL-6，IL-8和组氨酸脱羧酶在消化道各个区域的基因表达。

4.本研究表明，酵母聚糖抑制了雏鸡和白介素及组胺中饲料通过消化道的过程，可能参与了这一过程。
