Solubility Issues with Milk Replacer Powders— An Easy Fix

Abstract

Wildlife rehabilitators caring for young mammals prepare and use milk replacement formulas. Most rehabilitators, over the years, have dutifully followed the mixing instructions indicated on product labeling. Instructions generally say to add water, gently stir, and the liquid formula is ready to use. This paper discusses issues related to these products’ lack of complete solubility, laboratory tests performed to measure insolubility, and minor adjustments to formula preparation that easily address these issues.
