- Type of Hair
- The type of hair of the horse –forelock, mane, tail, and “feathers” (behind the fetlock).
- the hair coat of the pig; the cilia (eyelashes), vibrissae (hairs of the nostrils) and “beard” (hair of the submandibular region) of the goat.
- Composed of an undercoat of animals bred for their ability to produce usable fibers. Lacks guard hairs so that the fleece is soft and curly, made up of long fine hairs. Angora goat(mohair) and cashmere goat (cashmere wool) and camelids.
- It has an oily feel, a product of cutaneous sebaceous glands.
- Acquired from sheep (merino and rambouillet).
- It is Hair Follicles in Farm Animal that is single.
- It is Hair Follicles in Farm Animal that is compound hair follicles with single primary hair and a group of smaller secondary hairs
- It is Hair Follicles in Farm Animal that is single follicles grouped in cluster
- It is Hair Follicles in Farm Animal that issingle follicle with primary guard hair surrounded by clusters of compound follicles
- Hoof pads or bulbs are comparable to the digital pads of carnivores. The metacarpal, metatarsal, carpal, and tarsal pads are missing in all domestic species, except the carnivore.
- In sheeps, at medial canthus of eye, larger in rams than in ewes; used for marking
- In sheep, the midline above the hoofs between the digits of all four feet; are used as trail markers.
- In goats, Caudal to the base of the horn, secretion is increased during breeding season and especially pungent in bucks
- In goats,Two glands below the tail responsible for the buck’s characteristic smell
- In pigs, the mediopalmar aspect of the carpus; Produces sexual pheromones, marking the sow during mating
- In pigs, a wart-like skin eminence on the chin; has both tactile and secretory (marking) functions
- only in cats; in the skin around the mouth esp. the lower lip; called “cleaning glands” but functional significance is probably for marking
- In sheeps,Near the base of the udder or scrotum
- In pigs, is the secretions mix with degenerated cells to form a called substance smegma in horses
- Predominant in man. Restricted to the footpads of carnivores, frog of the horse, nasolabial region of ruminants and swine, and carpus of pig. Function relates to territorial markings and thermoregulation.
- Predominates in domestic species. Distributed throughout the skin, ducts open into hair follicles.
- is the only farm animal that sweat readily and sweats the most (“lathering up”), cat and dog the least.
- It is a sweat gland that occurs in cow
- It is a sweat gland that occurs in sheep and pig (in hairless area)
- are sensitive to circulating epinephrine. this is rich in protein and will foam when agitated by working muscles.
- Thought to be modified sweat glands that nourish the young.
- Term designating all the mammae in the ruminants and the horse (sometimes in sow).
- The four parts of the bovine udder are each associated with one teat; all four quarters are completely seperated from each other.
- External indication of the separation of the two halves of the udder
- usually 10 mammae; 5 (4-6) mammary complexes on each side separated by an intermammary groove.
- 8 mammae, four on each side of the ventral adominal wall.
- 14 (10-18) mammae; seven on each side.
- 4 mammae, two (quarters) on each side, all bound together to form an udder
- 2 mammae forming a pendulous udder.
- 2 mammae forming a small udder.
- teats; usually have the same number as females.
- extra teats may or may not be connected to primary mammary gland tissue in both male and females.
