Regulation of pancreatic exocrine secretion in ruminants: a review
Article Abstract:
The regulation of the exocrine function of the pancreas in both ruminants and nonruminants is reviewed. Among nonruminants, secretion of pancreatic digestive fluids is regulated by an array of control mechanisms that involve the central nervous system and hormonal signals from the entire gastro-intestinal tract. Since pancreatic control among ruminants, on the other hand, is poorly understood. Pancreatic enzymes enhance the digestion of nutrients within the gut, it is therefore necessary to understand regulatory mechanisms controlling pancreatic activity. Some of these mechanisms are discussed.

Determining optimal heat treatment of soybeans by measuring available lysine chemically and biologically with rats to maximize protein utilization by ruminants
Article Abstract:
The effect of heat treatment on the bioavailability of lysine in soybeans was investigated to maximize ruminant protein uptake. Heat effects were found to be dependent on the intensity and duration of treatment. Bean exposure to temperatures ranging from 140 degrees to 160 degrees Centigrade from 120 minutes to 30 minutes, depending on intensity, significantly increased the available lysine for intestinal absorption in ruminants. This indicates that roasting soybeans at the recommended temperature and duration will greatly increase its efficacy as a feed supplement.

Dietary influences on carbohydrases and small intestinal starch hydrolysis capacity in ruminants
Article Abstract:
Available literature on the effects of diet on intrinsic enzymes catabolizing carbohydrates in the gastro-intestinal tract of ruminants is reviewed. Alpha amylase concentration in the pancreas has been shown to be influenced by energy and carbohydrate intake. However, intrinsic carbohydrases in the small intestine are minimally affected by diet type and amount. Further studies elucidating dietary effects on digestive activites are recommended.
