abstract = {The study investigates the performance and adaptability of Nellore sires across different regions, focusing on weight traits at 205 days (W205) and 550 days (W550). Analysis reveals significant variations in progeny weight means among evaluated sires, highlighting the importance of sire selection for herd improvement. Notably, certain sires consistently exhibit superior weight traits across diverse environmental conditions, indicating their potential for widespread applicability. Regression analysis further elucidates the adaptability of sires to specific herds, with some demonstrating adaptability to favorable conditions while others exhibit stability across various regions. Additionally, variance components and coefficients of determination serve as valuable tools for assessing stability and predictability in sire performance. Findings emphasize the critical role of informed sire selection in enhancing herd productivity and resilience. By leveraging these insights, livestock producers can optimize breeding strategies to achieve long-term profitability and sustainability in diverse environmental contexts},
