High-producing ruminants require high-concentrate diets, but these can cause sub-acute ruminal acidosis (SARA). This study develops a novel three-step modeling approach to quantify individual dairy goats' adaptation to a high-concentrate diet using rumen pH as an indicator. The model summarizes post-prandial rumen pH kinetics, describes short- and long-term effects of the diet, and ranks goats based on their resilience. Results showed high individual variability in responses, with two main strategies: minimizing pH variations or oscillating between increases and decreases. This approach helps identify biomarkers for adaptation and optimize feeding strategies in precision livestock farming.
