Male Infanticide in Captive Plains Zebra Journal of Animal Behavior, 2000 Jan Pluhacek and Ludek Bartos 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 …showed first 75 words of 837 total…

The sooner the new male arrived after conception the more likely the mare would loose her foal. The survival rate for the foal was greater when the new male was introduced before or after the foal’s birth. The foal’s chance for survival also increased by being at least one month of age. ------------------------------------------------------------------------ **Bibliography**
