Implication

Experimental study reveals how dietary fat and non-milk proteins alter abomasal emptying and pancreatic enzyme output in calves, highlighting dietary effects on digestive efficiency.

Key Points

To determine the effects of dietary fat removal and non-milk protein substitution on duodenal digesta flow and exocrine pancreatic secretion in preruminant calves.
Studied four Friesian calves (N=4) fitted with duodenal and pancreatic cannulas fed four milk-substitute diets from 13 to 37 days of age.
Tested diets containing skim milk with or without margarine fat, or with 50% skim milk replaced by soy flour or fish-protein concentrate.
Collected 12-hour postprandial secretions and digesta using polyethylene glycol, tritiated lysine, and beta-carotene as fluid, protein, and lipid markers.
Pancreatic enzyme output peaked during the first hour after feeding, whereas the primary outflow of nitrogen and lipid occurred 5 to 10 hours postprandial.
Removing fat markedly lowered pancreatic fluid and enzyme secretions, but increased abomasal proteolysis, with only 42% of ingested protein marker exiting within 12 hours compared to 53% for the fat-supplemented diet.
Diets with soy or fish protein accelerated abomasal outflow of protein, reduced proteolysis efficiency, and tended to decrease overall pancreatic enzyme secretion compared to milk-protein diets.
