### Fitting the model to Dry Matter Intake (DMI) and Milk Fat Content (MFC) in goats before, during and after a 2 days nutritional challenge (grey rectangle).

<p>Data (observed values Â± SE) are expressed as fold changes. The inverse of DMI is illustrated since DMI is decreasing during the challenge. Stiffness (K) and resistance to change (C) parameters of the model were fitted on the mean of the DMI (K = 0.04, C = 0.06) and MFC (K = 0.72, C = 0.97) measures.</p

### Sensitivity analysis of the model where the parameter K varies and a continuous perturbation occurs between time 20 and 60.

<p>For this analysis, perc was set to 1, Fpert to 1 and C to 2. K varied between 0.1 and 1. We define the value T = C/K as the decay constant, characterizing the recovery capacity of the system, x<sub>max</sub> the value of x at the end of the perturbation and x<sub>inf</sub> the value of x if the perturbation continues indefinitely.</p

### Pearsonâ€™s correlation coefficients between model estimated parameters.

### Sensitivity analysis of the model where the parameter Fpert varies and a continuous perturbation occurs between time 20 and 60.

<p>For this analysis, perc was set to 1, K to 0.1 and C to 2. F<sub>pert</sub> varies between 1 and 10. We define the value T = C/K as the decay constant, characterizing the recovery capacity of the system, x<sub>max</sub> the value of x at the end of the perturbation and x<sub>inf</sub> the value of x if the perturbation continues.</p

### Model estimated (K and C) and derived (T and xinf) parameters, for two isogenic lines subjected to a confinement challenge.

### Fitting the model to cortisol release rate, oxygen consumption, group activity and group dispersion in rainbow trouts facing and recovering from a confinement challenge (grey rectangle).

<p>Data (observed values Â± SE) are expressed as fold changes. The model fit is shown for each measure by the solid line. Stiffness (K) and resistance to change (C) parameters of the model were fitted on the mean of the cortisol release rate (K = 0.028, C = 0.384), group activity (K = 0.143, C = 1.137), oxygen consumption (K = 0.314, C = 3.052) and the group dispersion (K = 0.542, C = 9.809) measures.</p

### Sensitivity analysis of the model where the parameter C varies and a continuous perturbation occurs between time 20 and 60.

<p>For this analysis, perc was set to 1, K to 0.1 and Fpert to 1. C varies between 0.5 and 20. We define the value T = C/K as the decay constant, characterizing the recovery capacity of the system, x<sub>max</sub> the value of x at the end of the perturbation and x<sub>inf</sub> the value of x if the perturbation continues indefinitely.</p
