Hormones affect the social behavior of guinea pigs. During estrus, the animals increasingly avoid confrontations.
Guinea pigs are social animals that live together in pairs or groups. There is a hierarchy among the animals, which is fought out through confrontations between conspecifics.
According to researchers at the Vetmeduni Vienna, animals that have a sense of when to assert themselves and when to retreat are the most successful and better integrated.
Stress in the hot phase
Stress hormones play a key role in this process, as they mobilize energy in the body for flight or fight. In behavioral experiments with female guinea pigs at different times of the menstrual cycle, the team of scientists observed that aggression occurs independently of the sexual cycle. In the so-called hot phase, however, the animals often fled in the face of the opponent.
On the other hand, peaceful “sitting together” could only be observed during non-estrous periods.
Interestingly, non-receptive animals sought physical contact despite high cortisol levels. This could serve as a stress buffer for the animals, according to study director Glenn.
