Veterinarian Andrés Cornejo and his sons are running a bovine genetic improvement project designed for commercial production rather than show circuits. Cabaña Las Veteranas held its first auction in July 2026, marking a milestone for a family initiative that prioritizes functionality over aesthetics.
Pedigree studs usually orient their selection toward criteria linked to rural shows and exhibitions, where judging by type and conformation prevails. That logic left, for decades, much of the commercial cattle industry disconnected from the sires available in the market.
The Cornejo family project set out to invert that trend, prioritizing productive indices such as fertility, weight gain and maternal aptitude.
The first auction of Las Veteranas was held in July 2026 with an initial offering focused on grass-fed Angus bulls evaluated using objective data on feed conversion efficiency and scrotal circumference.
The day attracted producers from the Cuenca del Salado and marginal areas, with average values below those of show studs but with good receptivity among breeders who prioritize economic results.
The Las Veteranas experience shows that there is a growing niche for studs producing functional sires, in line with the global trend of valuing pastoral and low-input cattle production.
If the model is replicated, it could create competitive pressure on traditional studs and expand the base of improving bulls available for Argentine cow-calf operations.
