The Pantothenic Acid Requirement of Poults for Early Growth

A HEATED diet which was satisfactory for pantothenic acid deficiency studies with chicks proved unsatisfactory for similar studies with poults, since even when it was supplemented with pantothenic acid, poor growth and high mortality results (Jukes 1938). Later results confirmed the inadequacy of the heated diet for poults, but experiments with an extracted type of ration indicated that the poult requirement of the vitamin for growth was definitely greater than that of chicks (Lepkovsky et al. 1945). A series of experiments with a modified heated ration was conducted to study deficiencies in the heated diet and to determine more accurately the level of pantothenic acid required for early growth of poults. EXPERIMENTAL In an attempt to formulate a basal ration which would produce a pantothenic acid deficiency in poults and would give satisfactory growth when supplemented with pantothenic acid, some exploratory experiments were conducted. In one trial the heated diet . . .
