Supplementation strategies for beef cattle managed in integrated systems: Impacts on animal production and grain yields

Abstract

Abstract The use of feed supplements can enhance land yield in crop‐livestock integrated systems (CLIS). Thus, a study was conducted in Montes Claros de Goiás, Brazil, between 2020 and 2023. The system comprised soybean [ Glycine max (L.) Merr.] cultivation during spring/summer (generally, sowing in November and harvesting in March), followed by Zuri guinea grass ( Megathyrsus maximus ‘BRS Zuri’) cultivation grazed by beef cattle (heifers) during autumn/winter (generally, grazing from May to August). Three supplementation strategies were evaluated during this period: mineral supplementation with an expected intake of 0.03% of live weight (LW), protein‐energy supplementation (0.5% of LW), and high‐intake supplementation (1.5% of LW). Each supplementation strategy was applied to three paddoc
