The scores were used to evaluate mother-infant interactions in the SPF breeding colony, and recorded in each female’s health record. Typically, a score was assigned upon first observation of an infant the morning after birth, then 24-, 48-, and 72-hr later. These scores were used to evaluate the likelihood an infant would thrive if reared by the mother.
