Pancreatic juice and duodenal fluid flow rate in cow calves from birth to early ruminant state.

The present investigation on pancreatic juice (PJ) and duodenal fluid (DF) was carried out in 10 crossbred (Jersey x Kankrej) male cow calves from birth to early ruminant state (15 week). The respective samples were measured in situ by cannulating the pancreatic duct and duodenal lumen, 30 minutes before feeding (BF) and 30 minutes after feeding (AF) both during morning (MH) and evening (EH). The results revealed significant increase in PJ and DF flow rate with age. Diurnal effect was nonsignificant except a significant increase recorded during EH on 4 d for PJ and 3 d for DF.
