Resumen
Cattle raising is the main agricultural activity worldwide (Gutiérrez et al., 2018). In the tropical regions of Mexico, cattle raising is practiced in extensive systems, in which vast extensions of land are used to grow native and introduced grasses (REDGATRO, 2018). This system accounts for 78.5% of the domestic production (García et al., 2018). Given their high cell wall levels, low digestibility, reduced protein content, and high nitrogen compound degradability, the quality of tropical grasses is associated with animal productivity (Rojo et al., 2000). This situation delays the growth of calves, reducing productivity and fertility (Rodríguez, 2011). Since feeding accounts for 70% of their total production costs, production units frequently seek to improve their feeding efficiency. Therefore, finding new feeding alternatives —which produce a biological and economic efficiency improvement— is fundamental (García-Balbuena et al., 2022).
