This document appears to be a midterm examination for an animal science course taken at Central Philippines State University. The exam contains multiple choice, fill-in-the-blank, and short answer questions testing students' knowledge of topics related to animal breeding and reproduction, including estrus cycles, hormones, sexual maturity, fertilization processes, and external anatomy of reproductive organs. It provides the course name, instructor's name, student identification fields, and sections for identification questions, enumeration questions, and a discussion question. The last page is a return slip for acknowledging the exam was discussed and returned to students.
