This course introduces the biotechnologies used in animal production and in the processing of animal products. It follows the chain from the farm to the factory: reproduction (artificial insemination, embryo transfer), genetics and genomics (genomic selection, genome editing), animal nutrition and health (feed additives, vaccines, rapid diagnostics), and dairy and meat processing (starter cultures, enzymes, biopreservation). It also covers authenticity and new products such as cultured meat and precision fermentation, and discusses the ethical, regulatory and economic limits of these technologies.
