Pigs can use their knowledge of other pig perspectives to their own advantage and even to influence others' behavior. [1] In one study, pigs used their theory of mind skills to mislead other pigs away from food rewards. [1] Like corvids and primates, pigs are capable of tactical deception. [15] [16] Pigs can figure where humans are looking and ...
Many people liken pet pigs to their pet dogs. Pigs are extremely intelligent, social, love to cuddle, and get along well with other animals. Another cute thing that they do just like dogs do is ...
Pigs are social animals and a female's social support network can play an important role in postpartum piglet-directed aggression. Free ranging pigs form sounders, or small social units, give young gilts the opportunity to observe gestation and parturition and exposing them to normal maternal behavior. [7]
Some rodent species (most typically males) will take the chance to kill neonates that are unrelated to them should opportunity permit. There is thought to be several benefits by doing so, which not only include nutrition benefits (particularly where food is in short supply [8]) but also non-direct benefits, such as allowing access to more resources, improving reproductive opportunities and the ...
Altricial birds are less able to contribute nutrients in the pre-natal stage; their eggs are smaller and their young are still in need of much attention and protection from predators. This may be related to r/K selection; however, this association fails in some cases. [18] In birds, altricial young usually grow faster than precocial young.
Romans sacrificed pigs to their gods and created an elaborate pork-based cuisine, including some dishes — such as roast udder of lactating sow — that could make even a gentile shudder ...
Possible reasons it was not treated as a prevalent natural phenomenon include its abhorrence to people, the popular group and species selectionist notions of the time (the idea that individuals behave for the good of the group or species; compare with gene-centered view of evolution), and the fact that it is very difficult to observe in the field.
Because of their relative lack of sweat glands, pigs often control their body temperature using behavioural thermoregulation. Wallowing , coating the body with mud, is a common behaviour. [ 9 ] They do not submerge completely under the mud, but vary the depth and duration of wallowing depending on environmental conditions. [ 9 ]
