Períodos discretos do comportamento ingestivo de bezerros de corte oriundos de vacas com suplementação injetável

Abstract

Cattle ranching for beef is an activity that has great economic and social relevance in Brazil. The country holds one of the largest herds in the world, being the largest exporter of beef. According to ABIEC (2022), Brazil traded with over 124 countries, selling about 2.48 million tons of carcasses. In line with this context, the production system of cattle in the country is based on pasture, presenting a significant growth potential, given the high availability of degraded lands that can be recovered. And because its basal diet is grass, it optimizes the efficiency of the system, as pasture is the least costly food source in ruminant farming. According to Figueredo et al. (2019), due to the irregular production of beef cattle in pasture systems caused by differences in water precipitation throughout the year, it is ideal to raise animals that utilize dietary nutrients more efficiently as a means to reduce.
