a decreasing trendp >0.05
The activity of amylase and trypsin in the duodenum were significantly reduced ( p <0.05), the lipase activity was non-significantly different ( p >0.05); the trypsin in the jejunum was significantly reduced ( p <0.05), but the activity of amylase and lipase showed a decreasing trend ( p >0.05); the amylase and trypsin activities in the ileum were significantly decreased ( p <0.05), while that of lipase were non-significantly changed ( p >0.05), as shown in Table 4 .
