Reference for Temurah 41:16

א"ל אביי

BUT NOT A FIRSTLING AND AN ANIMAL TITHED.<span class="x" onmousemove="('comment',' Since if these animals become blemished they are not redeemed so as to render the wool and the working of them permissible. Also the money obtained is not holy, as there is no need to bring another offering in their place, only when blemished they are eaten by the owners themselves.');">¹⁴</span>
