Effect of Duodenal Infusion of Glucose on Blood Parameters, Ileal Flow, and Digestibility in Preruminant Calves Fed a Nonclotting Milk Replacer

摘要: Abstract Four Holstein male calves, each fitted with a simple duodenal cannula and reentrant ileal at 7 to 10 d of age, were fed nonclotting milk replacer based on skim powder. The calves divided into two groups infused either saline (control) or saline-glucose solution (treatment) according switchover design. Glucose infusion improved N retention decreased plasma concentration amino acids urea. Insulin triglycerides in not different between the groups. Ileal flow digestibility dietary components affected by glucose infusion. data suggest that additional energy as is needed optimize utilization preruminant replacer.
