The Durvet Lamb and Kid Selenium/Vitamin E Gel Supplement is a unique combination of selenium and vitamin E at levels designed for goats and sheep. The selenium and vitamin E found in this sheep and goat supplement are all natural. Selenium and vitamin E gel is included in a real gel base that melts at body temperature so as goat and sheep supplements are administered, they will not roll off the tongue. There's no need for additional selenium goat mineral supplements; this gel is to be used as the sole source of selenium. Use this gel supplement with goats, lamb and sheep of all life stages.
