Scientific and technical book mainly focused on the management of pig farms working with hyperprolific genetics, which almost completely monopolise the market in this species in both productive and reproductive terms, and are the target of the most of the investment and research conducted in the field regarding search for optimization of productivity and profitability of farms. This is an innovative and updated work within pig production with a distinctly practical approach to the veterinarian technician. The author, a renowned experienced specialist with this type of genetic, provides key information to facilitate the management of these lines by veterinary professionals.
