  • Shiitake mushroom contains several therapeutic actions such as antioxidant and antimicrobial properties, carried by the diversity of its components. In the present work, extracts from shiitake mushroom were obtained using different extraction techniques: high-pressure operations and low-pressure methods. The high-pressure technique was applied to obtain shiitake extracts using pure CO2 and CO2 with co-solvent in pressures up to 30 MPa.

  • Ideally, multiple traits would be considered for selection, such as milk yield, AFC and longevity, to consider both production and functionality. Such a plan might be difficult to implement quickly, so, for more simplicity, evaluation could initially be based on ‘likeability’ scores assigned by the farmer. To evaluate likeability, farmers would be asked to assign an animal a score of from 1 to 5, where 1 and 5 indicate an extremely poor or good cow, respectively. Such a trait would comprise a mixture of productivity, reproduction and health.
