The term "livestock" is nebulous and may be defined narrowly or broadly.
Domesticated animals typically raised for production of food or fiber include pigs, cows, goats, sheep, horses, donkeys, mules, reindeer, alpacas, yaks, bulls and various types of poultry (including chickens, geese, ducks and turkeys). All of these are certainly livestock. In addition, camels, llamas, bison, peafowl, emus, and ostriches may be intentionally reared and be "livestock". This definition includes mammals and birds. The type of livestock reared varies worldwide and depends on factors such as climate, consumer demand, native animals, local traditions, and land type.
On a broader view, "livestock" could incorporate the intentional rearing of butterflies, silk worm and honey bees. Taking 'livestock' to mean 'domesticated animal' could include aquaculture, including fish, mollusks, shrimp or other water-borne invertebrates.
By contrast, on a very narrow view, "livestock" refers to red meat animals: cattle and lamb.
