Effects of intraruminal administration of zinc on gastric acid secretion in sheep.
Intraruminal administration of zinc sulphate at 100 and 200 mg Zn/kg bodyweight resulted in central and peripheral effects in sheep. Feed intake was reduced, pH of the duodenal contents elevated and the secretion of acid from isolated pouches of the abomasum doubled. Suggested explanations include a local inhibitory effect of zinc on abomasal acid secretion elevating duodenal pH and a resultant increased release of gastrin stimulating secretion from the pouches.
