Male infacticide in plains zebras
Male Infanticide in Captive Plains Zebra The department of Zoology and science faculty at Charles University planed this experiment with the following hypothesis. “Introducing a new zebra male into a herd of breeding females should increase foal Mortality in comparison with herds in which the sire of the foals is still present “ (Pluhacek and Bartos, 2000). The younger the foal the higher the infanticide rate. “Male Infanticide is the killing of newborns or young juveniles by an adult male”(Pluhacek and Bartos, 2000). The encouragement for this experiment came for data recorded from five herds in two different zoological gardens in the Czech Republic. Some of the data that was obtained during this experiment included, nine records of infanticide in plains zebras and three cases of abortion that was probably induced by force. Fifty percent of breeding mares conceive while still lactating. Most mares are providing nutrients for both foal and fetus. “When a new stallion is introduced he benefits more from initiating abortion than killing foals” (pluhacek and Bartos, 2000). The methods for this experiment are as followed. Five breeding herds of plains ze
