In addition to the six crystalline factors of the B group of vitamins, growing chicks maintained on the heated diet require the eluate factor in yeast (factor U), cartilage, and biotin. Factor U and biotin may be supplied by liver residue. Pantothenic acid, biotin and one or more factors in the factor U fraction are destroyed by the dry heat treatment.
