Unidentified Growth Factor(s) Present in Alfalfa Water-Solubles for Young Guinea Pigs 1

Abstract

Summary

At least one unidentified factor is present in alfalfa which stimulates growth (and may alter hematological values) in young guinea pigs. These factor (s) are organic, water soluble, partially methanol soluble, heat stable, and of relatively large molecular size (> 5000 mol wt) or attached to large molecules. They are active at low levels (1% or less) in a purified basal diet. Further studies are in progress to characterize these factors.
