Reproductive biotechnology applied to the farm animals

The research topic is related to the optimization of the use of inseminating dose in large ruminants. Innovative insemination catheters types will be compared intra and inter species. Ultrasonography (B-mode and Doppler), thermography, semen analysis, seminal plasma composition, natural fluids composition and semen filtering will be the main diagnostic tools integrated in the innovative approach to obtain a higher reproductive efficiency in farm animals (Bovine, Bubaline). Satellite experiments on other farm animals will be consider for new insemination catheters design.
