65863 - Innovative Reproductive Technologies in Zootechnical Species

Learning outcomes

At the end of the course the student should know the animal reproductive physiology. He/she should possess knowledge of the main reproductive biotechnologies applied to zootechical species.

Course contents

Estrous cycle: generalaspects and species-specific characteristics. Hormonal control of the estrous cycle. Follicular wave and ovulation. The luteal phase and the corpus luteum. Luteolysis: peculiaritiesof species. Seasonal reproductive activity. Induction and synchronization of estrus. Male reproductive system: hormonal regulation of the reproductive function. Gametogenesis, fertilization and embryo development. The endocrinology of pregnancy and parturition. Physiology of lactation. Physiology of reproduction in teleosts and in birds.

Semen collection and storage. AI with fresh, cooled and frozen semen. Sperm sexing. Multiple ovulations and embryo transfer (MOET) in cattle. Embryo transfer in horses. Collection and cryopreservation of oocytes. Principles of cloning and trangenesis.

Assessment methods

Written examination with the aim to evaluate if the student has acquired the knowledge related to the topics that have been treated during the course.

The written exam will consist of 60 questions (either multiple choice questions or very short questions with open answers); each multiple choice question will present a little number of alternatives and can have more than one exact answer. The score may be 0 (zero) or 1 (one) for each answer. In case of open questions, the answer must not exceed the available space. The score ranges between 0 (zero) and 1 (one) depending on whether the answer is exact and pertinent to the question. No answer will have a score equal to zero.

Since March 2020, due to COVID emergency, the exams have been carried out orally.  The grade of the oral exam will be decided according to the following "learning evaluation scale":

A very thorough knowledge of the topics covered in the course, together with high skills of critical analysis, link capacity and a confident command of specific terminology: maximum score (30-30L).

A thorough knowledge of the topics addressed in the course, together with a good analytical and critical ability and the possession of a sure command of specific terminology: good marks (27-29).

A technically adequate preparation and a sufficient analytical capacity, even if not particularly articulated, expressed in a correct language: fair evaluations (23-26).

A sufficient preparation and capacity for analysis, expressed in a language just formally correct: sufficiency (18-22).

The student will not have the possibility to use textbooks, memos or data storage devices.

The exam will be considered as passed if the total score is equal or above 32 points.

The final grade of the integrated course of Biotechnologies applied to animal production comes from the final evaluations of the different teachings that make it up, weighted on the CFU of each course.
