Further evidence for sex differences in suckling behaviour of captive plains zebra foals

Original language description

Sex differences in suckling behaviour could be explained either by different maternal investment or by different behaviour of young. Previously, we found sex differences in rejection and termination of suckling bouts in captive plains zebras (Equus burchellii). In this study, we analysed the length of suckling bout interruptions and unsuccessful subsequent attempts which followed a successful suckling bout in plains zebra foals at Dvůr Králové Zoo. When a suckling bout was interrupted, male foals resumed the bout sooner than female foals. The probability of a subsequent attempt decreased with increasing age in female foals but did not change in male foals. These results demonstrate higher effort in suckling interest by male foals, who tried to suckle more than female foals. Although we found sex bias in the effort to suckle, which suggested higher parent?offspring conflict in male offspring, we cannot omit a sex bias in milk supply by the mother
