Promiscuous behaviour disrupts pregnancy block in domestic horse mares

Popis výsledku v původním jazyce

Based on questionnaires from horse breeders, we found that bringing a pregnant mare which had been mated away from home into a vicinity of a familiar male who was not the father of her foetus increased probability of pregnancy disruption. These mares aborted in 31% of cases, while none of those mated within the home stable aborted. Repeated sexual activity either by a stallion or dominant gelding from the normal home group was observed shortly after the mare came from away-mating. Pregnant mares isolated from home males by a fence were even seen soliciting them over the fence. We speculate that, once returned to the home "herd", and introduced to familiar males, mares were more likely to terminate their pregnancy to save energy and avoid likely futureinfanticidal loss of their progeny by dominant male(s) of the home social group. This is a newly discovered phenomenon where a mare manipulates the male's paternity assessment by promiscuous mating. It may explain a common increased incid
