Effect of suckling isotonic or hypertonic solutions of sodium bicarbonate or glucose on abomasal emptying rate in calves.

摘要: Objective—To determine and compare the abomasal emptying rates in calves suckling milk replacer or an isotonic hypertonic solution of NaHCO3 glucose. Animals—5 male Holstein-Friesian that were < 30 days age. Procedures—Calves fed 2 L (300 mOsm/L) (600 solutions glucose containing acetaminophen (50 mg/kg). Venous blood samples transabdominal ultrasonographic dimensions obtained periodically after feeding, luminal pH was continuously monitored by placement a electrode through cannula. Abomasal rate assessed time to maximal plasma concentration, determination half-time emptying, for return within 1 unit preprandial value. Results—Hypertonic emptied slower than solution, ...
