Groups of breeding albino rats and mice of the dba strain were maintained on a commercial dog chow with and without a 100 µg. per gram supplement of calcium pantothenate.
During the course of the experiment fifty-eight control litters averaged 5.4 offspring per litter, and sixty litters produced by the animals on the vitamin enriched diet averaged 6.7 offspring per litter an average increase of 24% for the latter.
A study of brain and heart weights in day-old rats produced by control and experimental groups indicated that the calcium pantothenate supplemented diet was associated with a relatively smaller brain and heart in the offspring.
