Mother Are Concerned: The experiments of American sychologist Harry F. Harlow's work with moneys is relevant. He was concerned with the vari-bles that produced the bond between mother ad infant. Earlier theories had proposed that lis bond arose from the association of mother with le delivery of food, but Harlow demonstrated lat the tactual sensations from being held by le mother were even more important.
This prevents her from inflicting Rh disease on her next baby. Thus, each pregnancy after injection becomes a "first" pregnancy insofar as the blood antigens of the mother are concerned. The mother must, however, be revaccinated following each birth or miscarriage, because the vaccine's immunizing effects are only temporary.
Gestation takes 16 days; 7-15 in litter; young born pink, naked, and blind. Do not disturb young or mother for at least a week after birth; if disturbed mother will either kill and eat the young or neglect them and allow them to die. After 3 weeks, remove young from mother; otherwise, mother fights with them and often kills them. Sexes should be separated before young reach maturity at 43 days.
