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.

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 ...
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] This behaviour has been seen in captive bonobos, but not wild ones. It is not clear if it is a natural bonobo trait or the result of living in captivity. [2]
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]
Giant otters in captivity must be given privacy when raising their litters as cases of parental infanticide have been reported in the species, potentially caused by human visual and acoustic interference. Though not confirmed, it has been suspected that similar occurrences happen in the wild due to tourists. [1]
Some animals starve to death shortly after birthing their young while others are eaten by their own young -- but these mothers make the ultimate sacrifice. Click through for 10 animal mothers that ...
This is who is affected by abortion legislation.
White children are bred on ranches for consumption and slaughtered at around 12 to 14 years of age (when their flesh is considered particularly tasty) or sometimes already as babies. Boys are often castrated several years before their death, as that is thought to improve the quality of their meat. [122]
