Gastric and pancreatic enzyme activities and their relationship with some gut regulatory peptides during postnatal development and weaning in calves
Article Abstract:
A study was done on the relationship of gastric and pancreatic enzyme activities on some gut regulatory peptides during postnatal development and weaning in calves. It was shown that the values for enzyme activities increased with age for carboxypeptidases A and B, ribonuclease, alpha amylase, chymotrypsin and elastase and decreased with chymosin, colipase and lysozyme. It was further shown that enzyme regulation is modified by colostrum and milk intake as well as by weaning.

A method for estimating the available energy of incompletely digested carbohydrates in rats
Article Abstract:
A method used to estimate the available energy of incompletely digested carbohydrates in rats was evaluated. Comparison of values from radiolabeled breath, feces, carcass and intestinal contents was used to calculate for energy directly available by digestion. The method was found to be reliable compared to other methods despite the fact that it overestimates available energy because of the more efficient digestive metabolism of germfree rat.
