Introduction To Animal Science Chapter 1 Study Questions 2025

Define animal science. Why did animal science begin? - Correct Ans-It is the combination of disciplines that together comprise the study of domestic animals.(Easier definition: The branch of science that deals with domestic animals). It was caused by the need to manage, care for, and use domesticated animals to our advantage. Explain why all of the world's occupations are tied to agriculture. - Correct Ans-Every person depends upon agriculture for his or her daily food. When did animal domestication occur? When were each of the major animal species domesticated? - Correct Ans-No one truly knows when animal domestication occurred. However, archaeological evidence suggest that the dog was domesticated about 14,000 (1,200 B.C.) years ago. DNA sequencing technology, though, suggests that the dog was domesticated from a now extinct wolf as long as 30,000 years ago. The earliest domestic food animal species was sheep (somewhere around 8000 B.C ), followed by goats, pigs and cattle (6,500 B.C.); llamas (5,500 B.C.); horses (3,500 B.C.); donkeys (4,000 B.C.); reindeer (3,000 B.C.); chickens (6,000 B.C.). (Idea of how to remember: Rihanna Had Dog-Like-Cats Go Purchase Cat Stuff. Also, every other number has a 500 rather than just in the thousands if you organize them that way. Additionally, you just have to remember that there is not a 4,500 and it jumps up to 5,500 and then there is no 7,000 or 7,500 because it skips to 8000) Define the specialties of animal science. - Correct Ans-Genetics, Nutrition, Physiology, Animal Health, Animal Behavior, Meat Science. Dairy Product Science, and Biotechnology. (Idea of how to remember: GNPAHABMSDPSB - The way that my brain connects these letters is that GNPA sounds like Grandpa, HAB sounds like Had, MS spells Ms. and DPS is like Department of Public Safety and B is the only letter left out. So, the crazy sentence that my brain remembers is: Grandpa had Ms. DPS Baby. I know that I'm explaining my strange brain waves, so please come up with a way that makes sense to you! ) Genetics: Genetics is the science of heredity and the variation of inherited characteristics Nutrition: The study of nutrients and how the body uses them Physiology: The study of physical and chemical processes of an animal or any of the body systems or cells of the animal. ANIMAL ANIMAL Animal Health:The study and practice of maintaining animals as near to a constant state of health as is possible and feasible. (Other definition provided: The study of how diseases, parasites, and environmental factors affect productivity and animal welfare) Animal Behavior:The study of animal welfare assessment, optimizing production, behavioral control, behavioral disorders, and behavioral genetics. (Idea of how to remember: WAOPBCBDBG We Are Open People Because Cats Bring Dogs Bones Generationally. - the reason this sticks in my brain is because this is a strange animal behavior! Why would a cat bring a dog a bone and why does it only happen generationally?) Meat Science: The science of handling, distributing, and marketing meat and meat products. Dairy Product Science: The science of providing milk and milk products as food. Biotechnology: A collective set of tools and applications of living organisms, or parts of organisms, to make or modify products, improve plants or animals, or develop microorganisms Why is the specialization in animal science disciplines both a help and a hindrance? - Correct Ans-"By breaking the discipline of animal science down into smaller units, we have made it easier to learn but harder to grasp - we know the pieces of the puzzle better, but it is harder to put the pieces together. Always remember that it is the combination of the specialties that constitutes the whole discipline of animal science." - pg. 5 (bottom paragraph) Study table 1-1, which gives livestock numbers in the world. Notice the relative numbers of each species. Offer some reasons why animals are distributed as they are. Based on the numbers in this table, what are the world's major farm species? - Correct Ans- Table 1-2 gives an overview of the foods and services derived from domestic animals by humans. (These are explored in detail later in the text.) Develop a list of uses from this table that are ranked from "most useful" to "least useful" from your current perspective. (At the end of the book, come back to your list and see if your perspective has changed.) - Correct Ans-This question is a personal opinion question, so I can't really answer it for you! What proportion of human food energy and protein comes from animal products? - Correct Ans-17.7% of energy. 27% in the U.S. 40% of protein consumed by the world. What proportion of the U.S. calorie and protein supply comes from animal products? How do other countries compare? - Correct Ans-17 - energy world 27 - energy U.S. 40 - protein world ANIMAL ANIMAL 66 - protein U.S. If a person does not eat meat, what are the most common reasons? - Correct Ans Religion or cost Which animals supply most of the world's meat? - Correct Ans-I believe the answer it cattle based on the chart in the book, but please check me on that! Meat is important as a food door the human population because it is nutrient dense. What does "nutrient density" mean? - Correct Ans-A measurement of the nutrients provided in a food compared to the calories it contains. (Examples include: meat, eggs, and dairy products) List some of the important products made from by-products of the slaughter industry. - Correct Ans-1. Pharmaceuticals 2. Insecticides 3. Crayons 4. Cosmetics 5. Plastics 6. Cellophane 7. Glass 8. Water filters 9. Plywood adhesive 10. Soap 11. Gelatin 12. Air filters 13. Animal feed How important are draft animals to subsistence agriculture? Name six important draft animals. - Correct Ans-As much as 80% of the nonhuman power of subsistence agriculture is provided by draft animals. Draft animals include oxen, water buffalo, yaks, donkeys, camels, and dogs. (Idea of how to remember: Oprah Winfrey Bought Your Deaf Cute Dog) What is the role of animals in medical research? - Correct Ans-They provide a test subject other than humans and do not violate the majority of ethical laws found within science. Briefly discuss some of the ways that animals provide companionship, recreation, and entertainment to humans. - Correct Ans-Companionship and recreation: House pets (boosts mood, physical activity, and spiritual activity) along with service animals or therapy animals (they are two very different things) Entertainment: Horse races, rodeo, bull fighting
