This study was carried out on 10 crossbred male sheep aged 1-1.5
year. An innervated crosskopf abomasal fundic pouch was made in
each animal and effect o f starvation an d feeding on abomasal
volume and composition were assesed . The results indicated that
during starvation, volume of secretion , total acidity and K
concentration decreased to a low level, while pH and Na
concentration reached higher levels. Mainly, 60 minutes after
feeding, volume of secretion , total acidity, K and pepsin
concentrations were in creased , while pH and Na concentration
decreased (p<0 .05). The respective increase and decrease in these
factors continued up to 180 minutes, in relation to starvation
(p<0.05). The chloride concentration were increased after feeding
non significantly.
