Abstract: Beef cattle farming in Acre stands out as one of the main economic activities of the state’s agricultural sector, contributing significantly to both state and national GDP. The sector has experienced continuous growth, with herd expansion, technological intensification, and stocking rates exceeding the national average. Among sustainable intensification strategies, the intercropping of grasses with legumes—particularly Arachis pintoi—has proven promising. Studies conducted by Sales, Urbanski, Abreu, and others demonstrate substantial improvements in animal performance under intercropped systems, with notable increases in average daily gain (ADG) and productivity per hectare. Despite these advances, results show high variability, even under similar experimental conditions. This heterogeneity is attributed to environmental, management, and genetic factors, characterizing animal production as a stochastic process. In this context, the use of probabilistic statistical tools, such as probability distributions and frequency analysis, is essential. These tools allow risk estimation and performance forecasting, supporting robust decision-making and production planning. The chapter also addresses key concepts of randomness and stochastic variables, emphasizing indicators such as ADG, total weight gain, neutral detergent fiber, and crude protein. It highlights the importance of selecting appropriate probability distributions (Normal, Log-normal, Gamma) to represent production data and discusses methods like the method of moments and maximum likelihood for robust estimation. Frequency analysis is presented as a tool to predict the probability of productive events, using concepts such as exceedance risk and return period, with parallels to hydrology and economics. It concludes that the integration of technological innovation in livestock production with probabilistic statistical methods enhances sustainability, production efficiency, and resilience of cattle farming in Acre, strengthening its strategic role in the Western Amazon.
