Caracu: the secret of the rusticity and heat resistance of taurine cattle

Livestock farmers, the choice of a bull for extensive cattle farming in hot climates requires an in-depth analysis of its genetics. The Caracu, an adapted taurine, stands out for its unparalleled rusticity and resistance to heat. Check out the video below and discover more about the breed. Natan Eduardo, from Mirante (MA), asked what genetic and physiological characteristics of Caracu cattle contribute to its adaptation compared to other taurine breeds. On Tuesday, September 16, zootechnician Alexandre Zadra, an expert in genetics and industrial crossing of cattle, answered the question in the "Giro do Boi Responde" segment. He explained that the Caracu's adaptation is the result of a long process of natural selection and its physiological characteristics. The Iberian breeds, from which the Caracu descends, were brought to Brazil 500 years ago. The animals that survived this long process of evolution, by natural selection, were the most adapted to the tropical climate. The expert ...
