Unformatted text preview: Animal Science Exam Review Dr. Gentry 2007 Chapter 1—Introduction to Animal Science Vocab Domestic animals—those species that have been brought under human control and that have adapted to life with humans Hunter- gatherer—before agriculture, all these people were this kind. They supported their needs by hunting game, fishing, and gathering edible and medicinal plants Animal breeding and genetics—the study of the genetic code and how it can be changed and manipulated to produce more productive and healthier animals Physiology—the study of the physical and chemical processes of an animal or any of the body systems or cells of the animal Ethology—the study of animals in their natural surroundings Meat science—the science of handling, distributing and marketing meat and meat products 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 for specific uses Renewable resources—those resources that can be replaced or produced by natural ecological cycles or management systems Omnivore—an animal that eats both animal- and plant-based foods Calorie—a measurement of food energy Nutrient density —a measurement of the nutrients provided in a food compared to the calories it contains Diet —the total of the foods and water being consumed by an individual or group Essential amino acids—those amino acids required by the body that must be consumed in the diet Draft animal —an animal whose major purpose is to perform work that involves hauling or pulling I. Introduction a. Animal- mankind relationship precedes recorded history b. Domestic animals serve us in many ways i. Primarily for food ii. Welfare in other ways c. Hunter- gatherers->Farmers->Agriculture d. All people are dependent on agriculture for their existence e. The more developed a country is, the higher their standards of living become. II. Animal Science Specialties a. Animal Breeding (Applied Genetics) i. Utilizes genetics and its applications for successful animal selection ii. Helps to select best animals to be parents of next generation b. Nutrition i. Feeding animals ii. Combines feeds with feeding management to bring about the economical production of livestock and/or health and long life to animal companions c. Physiology i. Study of mechanisms of life ii. Broken down into the study of the workings of physiological systems 1. Reproductive physiology 2. Renal physiology d. Animal Health i. Study of how diseases, parasites, and environmental factors affect productivity and animal welfare ii. After domestication, disease and parasites became widespread iii. Causes around $17 million of value loss e. Ethology i. Animal behavior ii. Confinement systems reduce costs associated with labor and management and maximize feed use 1. Provide greater control of animals and maximize genetic potential 2. Bring about new problems with behavior f. Meat Science...
