This behavior is known as the "aunting to death" phenomenon; these non-lactating female primates gain mothering-like experience, yet lack the resources to feed the infant.

[1] Killing infants may also bring breastfeeding females out of lactational amenorrhea and back into fecundity, improving the male’s chance of fertilising the female if he returns to mate with her again soon.
