The University of Jordan Reproduction and Artificial Insemination Faculty of Agriculture (602451) (3 credit hrs) Dept. of Animal Production Prerequisite: Dairy production (602315) Lecturer: Prof. Mufeed Alnimer E-mail:- amufeed@ju.edu.jo COURSE DESCRIPTION:To learn the latest developments and methods that control estrus and ovulation in cattle and sheep. To develop the necessary skills required for improving the method of freezing of cattle and sheep semen. Provide students with the opportunity to learn recent developments in techniques of artificial insemination in cattle and sheep. Week Subject 1&2 INTRODUCTION LIVESTOCK IMPROVEMENT THROUGH REPRODUCTION AND ARTIFICIAL INSEMINATION Genetic improvement of cattle The role of Artificial Insemination Advantages of Artificial Insemination. 3 THE REPRODUCTIVE SYSTEM OF THE COW Origin and development The ovaries Tubular genitalia 4 THE ESTROUS CYCLE Hormones the regulate estrous cycle Puberty and first estrus Periods of estrous cycle Ovarian and tubular changes Artificial Control of estrous cycle 5 OVULATION AND FERTILIZATION Ovigenesis Ovulation Fertilization In vitro fertilization Superovulation and embryo transfer 6 GESTATION Preparation of the reproductive tract Changes in the uterus The hormones in pregnancy Diagnosis of pregnancy 7 PARTURITION Initiation of parturition 1 Signs of approaching parturition Normal and abnormal presentation of the fetus Stages of parturition. 8 THE REPRODUCTIVE TRACT OF THE BULL The scrotum The testes The duct system The accessory sex organs The penis 9 THE FORMATION AND EJACULATION OF SPERMATOZOA Spermatogenesis Spermiogenesis Endocrine control of spermatogenesis Transport of spermatozoa in the ducts Ejaculation 10 SEMEN AND ITS COMPONENTS Semen formation Composition of sperm cell Morphology of spermatozoa 11 PHYSIOLOGY OF SPERMATOZOA IN THE FEMALE REPRODUCTIVE TRACT Site of semen deposition Transport of spermatozoa in the female reproductive tract. Interaction between semen and the female reproductive tract. 12 SEMEN COLLECTION AND EVALUATION Methods of semen collection Gross examination semen Semen quality Morphology of sperm cells Concentration of sperm cells Motility of spermatozoa Staining of live and dead spermatozoa 13 EXTENDERS AND EXTENSION OF SEMEN Principles of sperm preservation Extenders for refrigerated semen Extenders for storage at ambient temperature. Extension procedures and rates 14 FREEZING SPERMATOZOA 2 Aspects of freezing and thawing Extenders for freezing Variation in semen quality 15 INSEMINATION OF THE COW Techniques of insemination Site of insemination Optimum time for insemination 16 CONCEPTION RATE AND FACTORS AFFECTING IT: Sterility and reduced fertility Measures of reproductive efficiency Physiological causes of reduced fertility COURSE OUTCOMES The practical portion or the course will allow students to develop the technical skills necessary to implement a successful Artificial Insemination program on their farm or ranch. Students should come out familiar with the basic principles and practices in the control of estrus and ovulation, handling and evaluation of semen quality, recent development in techniques of artificial insemination in cattle and sheep and how to prepare males and females for an artificial insemination program. Students will also learn methods of semen collection, dilution, cooling and freezing. CLASS PARTICIPATION Students are expected to attend classes on time, and fully participate in class work and discussions. Your attendance is crucial, as each class builds upon the previous class session. Actual participation in class work is a very important part of your learning experience in this course, so you are expected to come and to be prepared to do the work, ask questions, and fully engage with the course.
