Both the vitamin B12 and pantothenic acid (PA) in the diet of chicken hens influenced PA storage in eggs produced. Vitamin B12 deficiency in the hen diet intensified PA deficiency as measured by (1) hatchability of eggs, (2) growth and viability of progeny and (3) PA storage in the eggs produced. For the breeder hen, the PA requirement was not over 3.0 mg/lb. of B12-a-dequate diet, but was over 4.5 mg/lb. in a B12-deficient diet. The PA requirement tended to be higher for chick viability than for hatchability or for growth of surviving chicks.
