ANS 144 - Beef Cattle and Sheep Production
3 Credits / Spring 2013


The purpose of this course is to provide the student with information and skills needed for management of beef cattle and sheep production enterprises. This entails the integration and application of principles of genetics, physiology, nutrition and economic and business to the operation of these enterprises. In addition, current issues of concern to these livestock industries will be discussed.


The student should have had Animal Science 41 and upper division courses in nutrition and genetics, equivalent to Nutrition 115 and Animal Genetics 107. Also, some familiarity with micro-computing is required, such as Agricultural Science and Environment 21. A course in Range Science is recommended.
