The genetic improvement makes our animals grow more in less time and with less fodder year after year, also makes them more sensible, and as a consequence, the gains in terms of weight are penalized even more if the environmental conditions are not optimum. Exafan´s constant development has given as a result, the most complete range of computers capable of managing all the required factors for such environmental conditions to be perfect; this way we achieve some unbeatable conversion rates so highly valued by the integrators.
