Following a 14-d recuperation period, the pigs were fed two diets according to a crossover design, twice daily. Two maize starch-based diets were formulated to contain 12 and 24% CP from soyabean meal. The experiment consisted of 2 periods of 12 d each. The average BW at the start of periods 1 and 2 were 24.0 ± 1.1 and 31.3 ± 2.6 kg, respectively. The average BW at the conclusion of the experiment was 40.2 ± 1.6 kg. The daily volume of secretion was slightly higher (P 0.05) in total protein output in pancreatic juice although the protein concentration (g/l -1 ) was higher (P 0.05) of dietary CP level of the total activities (units 24 h -1 ) of chymotrypsin, trypsin, amylase and lipase. The specific activities (units l -1 ) of chymotrypsin and amylase were higher (P<0.05) when the high protein diet was fed. An increase in BW augmented (P<0.05) the secretion of volume of pancreatic juice, protein output and total activities of chymotrypsin and lipase. In conclusion, there were no differences in total protein output and total enzyme activities in pancreatic juice when the dietary CP content ranges from 12 to 24%. %A Li, S. %A Sauer, W.
