Effect of Coprophagy on Experimental Iron Absorption in the Rat

Abstract
In a 7-day experiment of radioiron absorption (ferrous-59 sulfate) in mature male Fischer rats the effect of coprophagy was studied in three groups: the control group; a group prevented from practicing coprophagy by anal tail cups; and a group with sham tail cups. Hematocrits were similar and normal in all. There was no difference in iron absorption between the “cupped” groups. The greater iron absorption of the control group was of borderline statistical significance.
