Technical note: An improved surgical model for the long-term studies of kinetics and quantification of nutrient absorption in swine

An improved technique to study kinetics and quantitative absorption of nutrients in pigs is described. Three female pigs (35 kg of BW) were surgically modified with catheters in the hepatic portal vein and carotid artery and an ultrasonic flow probe around the portal vein. Catheter placement and pat...
