Animal infanticide is studied in zoology, specifically in the field of ethology. Ovicide is the analogous destruction of eggs. The practice has been observed in many species throughout the animal kingdom, especially primates (primate infanticide) but including microscopic rotifers, insects, fish, amphibians, birds and mammals.

Infanticide in non-human primates occurs as a result of exploitation when the individuals performing the infanticide directly benefit from consumption or use of their victim. [1] The individual can become a resource: food ( cannibalism ); a protective buffer against aggression, or a prop to obtain maternal experience.
Scientists hypothesize that this is because many cheetah litters have cubs from different fathers and males would not want to kill any cubs in case they killed their own. [13] The promiscuity of female cheetahs helps to protect the threatened species not only by preventing infanticide but also by bringing greater genetic diversity. [ 15 ]
Some rodent species (most typically males) will take the chance to kill neonates that are unrelated to them should opportunity permit. There is thought to be several benefits by doing so, which not only include nutrition benefits (particularly where food is in short supply [8]) but also non-direct benefits, such as allowing access to more resources, improving reproductive opportunities and the ...

The Bruce effect, or pregnancy block, [1] [2] is the tendency for female rodents to terminate their pregnancies following exposure to the scent of an unfamiliar male. [3] The effect was first noted in 1959 by Hilda M. Bruce, [4] and has primarily been studied in laboratory mice (Mus musculus). [1]
