Tolerance reflex
In female mammals, the phase of rutting (also "heat" or, depending on the species, " horses ", " intoxication ", " heat ", " heat ", "bulls") is referred to as the tolerance reflex or phase of tolerance (sometimes also rigid tolerance ) in which the animal tolerates occupation (copulation) by a male animal. This is also known as the “standing time”, as the animals remain in a position that is favorable for penetration and allow the partner to jump up ( sawhorse position , turning the ears backwards, holding the tail to the side, presenting the vulva ) until the mating is completed is. Here play vertebrate pheromone and the Jacobson's organ (vomeronasal organ) play a key role.
In order to be able to determine the tolerance phase, a trial stallion, bull or boar or a search buck is often used. Even with geldings , many mares react with the corresponding attitude. In the case of cats and bitches, the presence of a male animal is usually sufficient to test willingness to tolerate. In the case of sows, the willingness to tolerate can be determined via flank grip , support and riding tests. For assigning the observation of toleration phase because in this period is important ovulation (ovulation) occurs.
Time:
- in the dog the last third of the heat , when the discharge clearly decreases
- in the case of the horse, one day before the end of the horse phenomena
- in cattle one day after the end of the symptoms of oestrus
In a figurative sense, the term rigid toleration is often used as a metaphor for human behavior in which one is passively waiting for change in an unpleasant situation.
