Caracu: the bovine genetics that adapted to the heat of Brazil. Understand

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. Natan Eduardo, from Mirante, in the state of Maranhão, asked what genetic and physiological characteristics of Caracu cattle contribute to its adaptation compared to other taurine breeds. Watch the video below. On Tuesday (16), the 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 adaptation of the Caracu is the result of a long process of natural selection and its physiological characteristics, which make it ideal for our climate. 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 ...
