title: Postprandial plasma zinc changes in pigs.
abstract: In growing male pigs fitted with jugular catheters, changes in plasma zinc concentrations were followed up to 330 min postprandially. In pigs with normal fasting zinc values (greater than 70 micrograms/100 ml) plasma levels decreased significantly (p less than 0.05) up to 35% below, whereas in pigs with lowered fasting values plasma level increased up to 36% above the respective fasting values within 120 and 180 min after feed intake. The amount of feed administered was without effect on the postprandial decline. No dose-response relationship between the intake of graded amounts of zinc in the inorganic (ZnSO4) or naturally bound form (barley) and changes in plasma zinc level was found.
