    The Effect of Feeding on: III Plasma Free Fatty Acids (FFA) Release and Uptake by the Hepatic Portal Drained Tissues and Liver in Normal Adult Sheep
    (Tanzania Veterinary Journal, 1991) Pereka, A .E.
    Adult sheep with implanted catheters in hepatic vessels were used to study the effect of feeding on hepatic plasma flow, plasma FFA concentrations and plasma FFA release and uptake by the liver. Sheep were fasted 48 hours prior to experiment, and feeding was restricted to last only 40 minutes. Splanchnic tissues were releasing FFA into portal vein at a rate of 1.73+2.27 mmole/min.kg0.73 while hepatic uptake was 6.58+0.22 mmole/min. kg 0.73 in fasted sheep. During feeding the splanchnic FFA release significantly decreased to 0.94+0.79 mmole/min. kg0 .73 as well as the hepatic uptake decreased to 2.42+ 1.5 mmole/min.kg0.73
