72711 - Biotechnologies Applied to Animal Reproduction, Genetic Engineering and Cloning

Learning outcomes

The student will learn developmental biology epigenetics of gametes and embryos in physiological and pathological conditions. The student will be able to perform collection, handling, preservation of gametes and embryos of livestock species. Assisted reproductive techniques, sexing of embryos, nuclear transfer cloning. Genetic engineering of livestock species. Set up and management of laboratory and equipment for assisted reproduction. The student will learn to work in a team and work in a laboratory. He/she will be able to understand the impact on health and welfare on the animals of the techniques both for agriculture and biomedical applications.

Slides and papers provided by the teacher

Teaching methods

Lectures with power-point presentation support to deliver information, ideas and theories on animal reproduction and connected technologies of main livestock species. Classes will be complemented by practical laboratory sessions to give an insight into a working environment, knowledge of experimental methods and techniques and an understanding of academic material taught on the course. These sessions will be hands on so that each student can immediately practice what he /she has been shown or taught during lectures with the equipment available. During the week of exercise, the students, in groups of 5/6, must submit a research project (the bibliography, objective, materials and methods, aim to be achieved) power point taking a cue from one of the topics covered in class.

Assessment methods

There will be an oral examination that will consists of questions to assess what the student has learnt during lectures and the techniques that have been practiced during training in the teaching laboratory.In the final evaluation and drafting of the questions the teacher will take into account the presentation made to exercise.

Teaching tools

Use of PC with multimedia projector, videos, scientific publications in specialised journals, specialised web sites. For laboratory sessions specialised equipment will be used for recovery, handling, manipulation and for cell culture.
