Pigs possess both apocrine and eccrine sweat glands, although the latter are limited to the snout. [6] Pigs, like other "hairless" mammals such as elephants, do not use thermal sweat glands in cooling. [7] Pigs are less able than many other mammals to dissipate heat from wet mucous membranes in the mouth by panting.
The protruding teats and accompanying glands can be located anywhere along the two milk lines. In general, most mammals develop mammary glands in pairs along these lines, with a number approximating the number of young typically birthed at a time. The number of teats varies from 2 (in elephants and anthropoids) to 18 (in pigs).
A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring.Mammals get their name from the Latin word mamma, "breast".The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs ...
An udder is an organ formed of two or four mammary glands on the females of dairy animals and ruminants such as cattle, goats, and sheep. [1] An udder is equivalent to the breast in primates, elephantine pachyderms and other mammals. The udder is a single mass hanging beneath the animal, consisting of pairs of mammary glands with protruding ...
These glands include the sudoriferous glands (located on the forehead, between the antlers and eyes), the preorbital glands (extending from the medial canthus of each eye), the nasal glands (located inside the nostrils), the interdigital glands (located between the toes), the preputial gland (located inside the foreskin of the penis), the ...
The glands are located in large preorbital pits in the lacrimal bone, and are surrounded by specialized facial muscles that compress them to express the secretions more effectively. In contrast, the saiga antelope ( Saiga tatarica ) is a polygamous and somewhat nomadic species which does not occupy any permanent territory at any time during the ...

Male fetal pigs have an urogenital opening located behind the umbilical cord. The swelling behind the hind legs of the fetal pig [ 24 ] is the scrotum . The male's internal reproductive system has two scrotal sacs, which depending on the age of the fetal pig may or may not have developed testes . [ 25 ]
