Análise da pecuária de precisão

Abstract

Precision livestock is a management concept applied within animal production with the objective of collecting data through the introduction of technologies that will assist the producer or technician in decision making. The application of precision livestock concepts in Brazil was initially more widespread in poultry and pig farming, with Brazilian livestock still considered traditional in terms of data collection. In cattle breeding, the use of more intensified systems, using automatic weighing scales installed in the pasture, electronic earrings and necklaces, injectable transponders, the use of infrared thermography to detect diseases such as mastitis and laminitis, and the use of of infrared cameras to measure the score and body condition of the animals. In Brazil, the most frequently measured parameters using precision technologies and considered most useful by the largest milk producers are daily milk production (4.67), estrus detection (4.43) and mastitis (4. 26). In poultry and pig farming, the technology and air conditioning of the facilities guarantees the well-being of the animals and the highest productivity of the system. Technified installations such as raising chicken in dark house aviaries showed a greater performance in weight gain compared to animals raised in traditional systems, with a daily weight gain of 0.0705 kg and 0.0630 kg, respectively. The concept of precision animal husbandry, despite being widespread in the country, is still being retaliated against by producers due to the costs of acquiring technologies and the cultural aspects of production.
