Animal Science Exam 1 With Questions AndCorrect Answers Latest Version
Per-capita calorie and protein supply Answer: the supply of calories and protein on a per person
basis specific to a region or population.
mechanization Answer: application of technology and machinery to a process.
animal agriculture Answer: application of human creativity to the stewardship of livestock to
produce fiber, food numerous by-products, and draft power.
chronic persistent hunger (CPH) Answer: a state of consistent malnourishment.
famine Answer: a shortage of food due to a catastrophic event that disrupts the food supply
infrastructure from hurricanes, drought, or civil war.
food secure Answer: situation where all family members have sufficient and predictable access
to an appropriate diet.
food insecure Answer: situation of limited or uncertain access to an appropriate level of
nutrients.
by-products Answer: product of considerably less value than the major product.
ex. U.S. meat animals hide,pelt and offal are by products and meat is the major product
gelatin Answer: by-product created from connective tissue
,draft purposes Answer: to use animals as a source of power
companion animals Answer: animals kept as pets.
compare and contrast the global distribution of livestock and poultry Answer: The world
numbers for livestock are far less than poultry. Both of their uses come mainly from their meat;
outside apparel and what they produce (milk and eggs). Livestock was domesticated earlier than
poultry and livestock was mainly for draft purposes, whereas poultry was for food.
Describe the role of animal products in the diets of consumers in developed and developing
countries Answer: Per-capita caloric supplies of both calories and protein have increased in
more areas of the world. The contribution of animal products to the per-capita protein supply has
increased in most of the world. The differences between countries in the importance of animal
products in their food supply can be mostly explained by available resources and development of
those resources.
How have expenditures for food purchased at home, away from home, and on a per capita basis
changed over time? Answer: Mechanization has resulted in an increased food production and is
allowing people to turn their attention to professions other than production agriculture. At-home,
the US has had an increase in the productivity of agriculture and has lowered their relative costs of
food. Away-from-home, most countries with only a small percentage of the population involved in
agriculture have higher standards of living and a higher per-capita consumption of animal products.
Releasing people from producing their own food has given them the opportunity to improve their
per-capita income with abundance of animal products so reduced costs of animal products.
Describe the role of animal products to the global caloric and protein supply. *possible essay
Answer: Animal products are primarily a source of proteins and essential amino acids, but when
they are a major constituent of the human diet they also contribute a significant portion of total
calories. In developed countries, they provide more than 30% of calories in the diet. In developing
countries, however, this proportion is less than 10% but they are a good source of amino acids that
balance the largely vegetable based proteins.
,Describe the hunger situation in the United States. *possible essay Answer: Even developed
nations, such as the US, are not immune to the effects of hunger for part of the population. 85% of
households in the United States are considered food secure. About 15% are labeled food insecure
which is divided into two categories: 9% without hunger,which are the people that are able to gain
access to groceries via food assistance programs or community outreach programs and then 6%
with hunger. Only .7% of children in the U.S. are food insecure coupled with periods of hunger.
Define the value of nonfood values of the livestock and poultry industries. Answer: Clothing by-
products include wool, hair, hides, and pelts. There are tallows and greases which are used as
lubricants and industrial uses. They can manufacture pharmaceuticals, candles, cosmetics, and
leather goods. Livestock contribute to work and power needs, companionship, and research.
cash receipts Answer: gross sales form a specific enterprise or set of enterprises.
world trade Answer: trade across the globe that influences probability of US animal industries
beef industry Answer: a coordinated set of supply chain enterprises that produce, process, and
distribute beef and beef byproducts to the market place
cow-calf Answer: management unit that maintains a breeding herd and produces weaned
calves
stocker-yearling Answer: weaned cattle that are fed high-roughage diets (including grazing)
before going into the feedlot
feedlot Answer: enterprises that utilize high energy rations to grow cattle (sheep) to ideal
market weights
commercial feeders Answer: 1) a carcass grade of cattle; (2) livestock that are not registered or
pedigreed by a registry association
, farmer-feeders Answer: smaller feed yards managed as part of an integrated farming operation
to market high energy feed-stuffs produced on the farm
dairy industry Answer: a coordinated set of supply chains enterprises specifically in place to
produce, process, and distribute milk products and byproducts to the market place
Eohippus Answer: an early ancestor to the modern horse
horse industry Answer: a loosely coordinated set of enterprises focused on the recreational,
working, and sporting use of horses
poultry industry Answer: the raising of domesticated birds such as chickens, ducks, turkeys and
geese for the purpose of farming meat or eggs for food
tariff Answer: taxes or fees placed on imported goods often used as political leverage
broiler Answer: a young meat-type chicken of either sex (usually up to 68 weeks of age)
weighing 35 lbs. Can also be referred to as a fryer or young chicken
browse Answer: woody or brushy plants. Livestock feed on tender shoots or twigs
forbs Answer: weedy or broadleaf plants, as contrasted to grasses that serve as pasture for
animals
sheep industry Answer: raised principally for their meat (lamb and mutton), milk (sheep's milk),
and fiber (wool)
