Aditivos na nutrição de bovinos

Abstract

In Brazil, cattle are raised mainly in pasture-based systems, which represent a complex nutritional source, since the low concentration of dry matter in these feeds is a factor that can compromise animal performance, especially during dry periods. To overcome this limitation, the use of nutritional additives, such as ionophores, non-ionophores, enzymes, probiotics, plant extracts and essential oils, has been an efficient strategy to improve ruminal fermentation and optimize nutrient utilization. The choice of the ideal additive should take into account factors such as diet composition, animal nutritional requirements and supplementation objectives, always balancing productivity, animal welfare and sustainability. With the growing search for natural alternatives, additives such as probiotics and essential oils have been standing out as viable options, providing benefits similar to traditional additives, but with a lower risk of residues. When incorporated strategically and supported by technical knowledge and good management practices, additives can contribute to the efficiency of livestock production, ensuring profitability, food safety and reduced environmental impact.
