Worthington (1993) using iodine to reveal non-hydrolyzed
starch. Lipase activity was determined by measurement
of fatty acids released by enzymatic hydrolysis of
triglycerides in a stabilized emulsion of olive oil
(Borlongan, 1990; Jin, 1995). Cellulase activity was
measured according to Jin (1995). Protease, amylase,
lipase and cellulase activities are expressed as specific
activity (U g−1 intestine content).
Statistical analysis using one-way analysis of variance
(ANOVA; Statistical Analysis System, SAS, version
6.03) was used to find any significant difference between
various parameters for the treatment and Control groups.
A significance level of Pb0.05 was used.
