ABSTRACT
The bioavailability of zinc from feed rations contained zinc oxide and Zn-glycine was determined in growing lambs’ investigation. Apparent absorption and retention of zinc as well as content of zinc in selected soft tissues were accepted as an indices of zinc bioavailability. Apparent absorption and zinc retention were greater in lambs receiving Zn-glycine than in the control group. Similar tendency for content of that microelement in kidneys and liver was stated. Obtained data point out better bioavaliability of zinc form Zn-glycine than zinc oxide.
Key words: zinc, zinc oxide, Zn-glycine, apparent absorption, bioavailability.
