Cebadero

A 90-minute, 4-round basic Express simulation for Spanish vocational training (Formacion Profesional), module 0478 Produccion de carne y otras producciones ganaderas of the Tecnico en Produccion Agropecuaria (Real Decreto 1634/2009).

The learner is Lucia Zarzoso, a newly qualified manager of a fictional family beef feedlot of 750 calf places in a village of Salamanca (Castilla y Leon) through the 2027-28 feeding year, with 486 tonnes of live weight to gain and a feed budget of 174.3 euros per 100 kg gained.

Four situations set the feedlot's course: October 2027, and how the calves are bought (by lot from known farms, with their history, not the cheapest calves from three markets) and how they are fed (a ration by phase, not the finishing feed from the first day); January 2028, and how the calves are kept healthy (a health plan with the vet) and how many go in each pen (each pen at its planned number, aired); April 2028, and when each lot goes to the slaughterhouse (at the weight its next kilo says, not forty days more) and how the sheds face the heat (clean water, shade and ventilation); and July 2028, and how sick, lame and dead calves are handled (a protocol with the vet, no unfit calf loaded, the authorised collection) and how the year is closed (gain, conversion, cost and records in order).

Two critical errors cap the round: giving every lot an unlabelled growth product bought from a dealer, and loading lame or sick calves for the slaughterhouse. Some mistakes look fine on the day and come back periods later. KPIs: gain reached (per cent of the attainable), feed cost per 100 kg gained, calves treated per 1,000 and calves dead. Lesson: every extra kilo costs more feed than the one before.
