The productivity of livestock is dependent on good reproductive management. Production-oriented selection pressure (meat, milk, etc.) has had adverse consequences on animal fertility. Having made this observation, researchers in the field of livestock have never ceased to try to increase reproductive performance by adopting modern methods of livestock management, both in terms of the management of reproduction and nutrition, only by using biotechnology techniques such as the production of embryos in vivo and in vitro. Research has also focused on reducing the pressure of pathologies having a direct or indirect impact on reproductive performance, whether of bacterial, viral, parasitic, nutritional or metabolic origin. By organizing this seminar, we try to shed light on all aspects related to the reproduction of farm animals in different species. Recommendations will be put in place to reduce the influence of limiting factors in order to optimize the reproductive performance of the animals, and manage to use their production potential as well as possible. At the end of the seminar, convention and scientific and educational collaboration projects will be discussed with our partners and our invited representatives of affiliated training structures.
