QUESTIONS AND CORRECT ANSWERS
Question:
1. Grains and pulses can be fed to livestock and also consumed by humans to meet their dietary needs.
Answer:
True
Question:
2. While a discussion of competition between humans and livestock for grain and other high quality foods
is largely of philosophical interest and without relevance for the real world, there is no question that
animals and humans compete for all feed items used in their diets.
Answer:
False
Question:
3. Along with the domestication of animals, man also moved towards the ingestion of cereal grains as a
major component of his diet about ________ years ago.
Answer:
10,000
Question:
4. The cereal grain that is consumed by humans and livestock in the greatest quantity in the world today is
______ ?
Answer:
Maize
Question:
5. From a dietary perspective, chickens are best described as _________.
Answer:
Gramnivores
Question:
6. When cereal grains replaced animal-based meat diets for hunter-gatherers the following physiological
events could be attributed to this change in their diets. From the list below, please choose all events which
are correct.
Answer:
Reproduction in Stature Increase in iron-deficiency anemia Increase in osteomalacia and osteoporisis
Decrease in lifespan Increase in infectious diseases
Question:
7. Based on traditional natural diets of swine and poultry, neither are considered to be competitors for
human feed items. However, in today's industrial farming of these species, every feed item they consume
in their ration makes them a primary dietary competitor for humans.
, Answer:
False
Question:
8. Today, intensive modern livestock production of swine and poultry in both industrialized and
developing countries is based on feeding grains and other concentrates to finish these animals to market
weights.
Answer:
True
Question:
9. Today, corn is a major source of mammalian dietary carbohydrates that is primarily grown for livestock
and poultry feed in the US.
Answer:
True
Question:
10. Birds excrete uric acid, an excellent source of nitrogen found in dried poultry waste, which can be
effectively used by ruminants and swine as a source of non-competitive nitrogen for protein synthesis (as
long as we are cautious about possible drug residues and possible high copper levels).
Answer:
False
Question:
11. By reducing meat consumption in developing countries, this practice is not only good for humans but it
will have the additional significant advantage of improving the health of people in developing nations
through the release of large amounts of grain for their direct and efficient consumption (i.e. more net
energy available).
Answer:
False
Question:
12. Even though industrial production of pigs and chickens have made them competitors for human feed
stuffs, their energy efficient short cycle physiology and use of feed stuffs that would otherwise be wasted
by man make them ideal livestock for man to use as a source of meat in developing and developed nations.
Answer:
True
Question:
13. In an ideal world, the greatest potential for raising livestock in a non-competitive way for humans in
developed nation is through the efficient use of crop residues and a minimum of concentrate feeding.
Answer:
True
