Abstract

This experiment was carried out to investigate the effects of dietary mulberry leaf power on gastrointestinal function of rats. Plot containing one and ten percent mulberry leaf powder was supplied with rats. The food efficiency ratio (FER) of rat fed with 10% mulberry leaf powder was decreased 14%. the transit time of rat fed with 1% and 10% mulberry leaf was faster 16% and 21% than that of control respectively. Intestine length was increased 10% and 11% at 1% and 10% dietary mulberry leaf respectively. The transit speed was faster 30% at 1% dieatry mulberry leaf than that of control. The pH of rat's feces supplied with mulberry leaf was lower than that of control. The amount of daily rat's feces fed mulberry leaf was much than that of control. As above results, we suggest that mulberry leaf was evaluated to improve the function of rat's gastrointestine.

흰쥐에게 뽕잎을 4주동안 투여하여 장기능에 미치는 영향을 알아본 결과, 사료이용효율은 10% 투여구에서 14% 감소되었고, 장 통과시간은 1% 투여구에서 16%, 10% 투여구에서 21% 빨라졌다. 장의 길이는 1% 투여구에서 10%, 10% 투여구에서 11% 증가되었고, 장 통과속도는 1% 투여구에서 30%, 10% 투여구에서 40% 빨라졌다. 변의 pH는 대조구가 6.91인데 비해 1% 투여구는 6.07, 10% 투여구는 5.95로서 뽕잎 투여량이 증가함에 따라 변의 pH는 점차 낮아졌다. 변량은 1% 투여구에서 57%, 10% 투여구에서 91% 증가되었다. 변중의 무기성분 중에서 K의 함량이 50% 증가하였으나, 이는 뽕잎 중에 K함량이 많기 때문으로 생각된다.
