The document discusses the economic value and uses of livestock. Livestock are raised for food including meat and dairy products. They also provide fiber materials like wool and leather. Manure from livestock is used as fertilizer and livestock can be used for labor like plowing fields. The grazing of livestock can help manage land by reducing risks of wildfires. Poultry farming specifically focuses on chickens, which are the most numerous farm animal, raised for both meat and eggs globally in the billions each year.

5.  The term "livestock" as used in this article does not
include poultry or farmed fish; however the inclusion
of these, especially poultry, within the meaning of
"livestock" is common.

component of modern agriculture.
 It has been practiced in many cultures since the
transition to forming from hunter-gather lifestyles.
‘Livestock’ are defined, in part, by their end purpose as
the production of food or fiber, or labour.

6. The economic value of livestock
 Meat
The production of a useful form of dietary protein
and energy.
 Dairy products
Mammalian livestock can be used as a source of
milk, which can in turn easily be processed into
other dairy products, such as yogurt, cheese,
butter, ice cream.

7.  Fibre
Livestock produce a range of fibre/textiles. For
example, sheep and goats produce wool and mohair;
cows, deer, and sheep skins can be made into leather;
and bones, hooves and horns of livestock can be used.
 Fertilizer
Manure can be spread on fields to increase crop
yields. This is an important reason why
historically, plant and animal domestication have
been intimately linked. Manure is also used to
make plaster for walls and floors, and can be
used as a fuel for fires. The blood and bone of
animals are also used as fertilizer.

8.  Labour
Animals such as horses, donkey, and yaks can be used
for mechanical energy. Prior to steam power, livestock
were the only available source of non-human labour.
They are still used for this purpose in many places of
the world, including ploughing fields, transporting
goods, and military functions.
 Land management
The grazing of livestock is sometimes used as a way to
control weeds and undergrowth. For example, in areas
prone to wild fires, goats and sheep are set to graze on
dry scrub which removes combustible material and
reduces the risk of fires.

12.  Poultry are farmed in great numbers with chickens being the
most numerous.
 More than 50 billion chickens are raised annually as a source of
food, for both their meat and their eggs.
 Chickens raised for eggs are usually called layers while chickens
raised for meat are often called broilers.
 In total, the UK alone consumes over 29 million eggs per day.
 In the US, the national organization overseeing poultry
production is the Food and Drug Administration (FDA). In the
UK, the national organization is the Department for
Environment, Food and Rural Affairs(Defra).
