This study develops a quantitative simulation-based predictive model to assess the potential of slick hair genetics in maintaining milk production under increasing Temperature–Humidity Index (THI) conditions in lowland smallholder dairy systems in Java, Indonesia. Secondary climatic, genetic, physiological, and production parameters from studies published between 2020 and 2025 were integrated into four THI scenarios. Predicted milk yield declined in both genetic groups as THI increased, but the reduction was smaller in slick dairy cows than in non-slick dairy cows, at 8.04% and 10.11%, respectively. The slick genetics × THI interaction indicated a buffering effect on heat-related production losses. These findings support slick genetics as a potential climate-adaptation strategy, although longitudinal field validation using genotyped dairy cows remains necessary.
