The Santa Inés breed of cattle, originally from Brazil but with improved genetics imported from Paraguay, is gaining popularity in Argentina. Argentine producer Mauro Pintos has seen success with the breed, which is rustic but requires care in colder climates. The breed has shown potential, with instances of quintuplets and triplets. However, the lack of diversity in bloodlines due to inbreeding is becoming a challenge. Pintos suggests the need for more imports to introduce new bloodlines. He also emphasizes the benefits of a commercial relationship and technology exchange between Paraguay and Argentina, despite the challenges of legal and financial barriers.
