A Method for Determining the Ash Content of the Leg Bones of Chicks With Slipped Tendon

Abstract

STUDIES which have previously been reported indicate that the ash content of the leg bones of chicks afflicted with slipped tendon is not significantly different from that of the leg bones of apparently normal chicks of the same nutritional history. In most of these studies the bones of chicks afflicted with the disorder were taken at the end of the experimental period, and the chicks having slipped tendon were compared with normal chicks from the same lot. There are two disadvantages in this method. It is entirely possible that the chick which one chooses as normal might have developed slipped tendon within a short time and is, therefore, not really a normal chick. This difficulty can be somewhat obviated by choosing a sufficiently large sample. The practice of analyzing the bones of chicks with slipped tendon only after the chicks are eight or ten weeks of age is open to .
