The efficient production of feed for broiler chickens faces the challenge of achieving homogenous and stable mixtures, as the lack of uniformity may compromise the nutritional quality and profitability of the final product. In this context, mixing time is a crucial factor influencing both blend homogeneity and moisture content, essential parameters to ensure the feed quality. This study evaluated the effect of five mixing times (60, 90, 120, 180, and 210 s) on uniformity and moisture percentage of the broiler feed using ferromagnetic microtracers and advanced statistical analysis. Homogeneity was assessed using the coefficient of variation (CV) and the Poisson distribution, whereas moisture content was analyzed using non-parametric tests. The results showed that intermediate mixing times (120 and 180 s) resulted in homogeneous mixtures (CV < 10%), in contrast to the shortest and longest durations, which exhibited greater variability. Although the Kruskal–Wallis test revealed significant differences in moisture content across different mixing times, Spearman's correlation suggested no direct, linear relationship between mixing time and moisture. These findings underscore the importance of establishing an optimal mixing duration, particularly in the range of 120 to 180 s, to enhance feed quality, improve process efficiency, and reduce production costs, thereby contributing to the sustainability of the poultry industry. |
