Document Summary
Aggressive behavior between sows after mixing: body lesions in the lose herds, vulva lesions caused by biting. Aggression is behaviour that causes or leads to harm, damage, or destruction of another organism: fails to include hostility and threat, behaviourally speaking threat and hostility appear as separate processes, but from neurological view it is similar. Types of aggression: predatory aggression: unrelated to other forms of aggression, attack response triggered by prey, fear induced aggression: animal prevented from escape, maternal aggression: when offspring is in danger, mother defends them. Aggression can turn to violence: injurious form of offensive aggression that is out of control and out of violence, no additive function. Differs both quantitatively and qualitatively from normal adaptive offensiveness. Physiology of aggression: based on brain mechanisms, brain steam consists of medulla oblongata, pons and midbrain (mesencephalon) connects spinal. Learning and hormones cord and rest of brain.
