This document appears to be a midterm examination for an animal science course covering cattle breeding topics. It contains multiple choice and short answer questions testing students' knowledge of cattle terminology, breeding systems, cattle raising operations, and cattle physiology. The exam is divided into four sections addressing definitions, identification, enumeration, and discussion of key terms. Some example questions identify the correct definition of progeny test, types of cattle raising in a cow calf operation, and ask students to discuss the estrus cycle and post-partum physiology. The exam was prepared by an instructor and includes spaces for students to write their answers.
