To generate the linear regression, digesta Ca outputs were regressed against dietary Ca concentrations by using thefollowing statistical model:
CaO-DMI(g/kg) = (TCaI × CaI) + IECaL
IECaLwhere, CaO-DMIrepresents the Ca concentration in digesta on DMI basis (dependent variable), CaIrepresents Ca concentrationin diet on DM basis (independent variable), TCaI represents true Ca indigestibility, and IECaL represents the mean ilealendogenous Ca estimates on DM basis. In this equation, TCaI and ECaL are the slope and intercept, respectively, of the simplelinear regression of CaO-DMIon CaI.
True Ca indigestibility is an indirect measure of the inefficiency at which dietary Ca is extracted by the birds. The trueileal digestibility Ca digestibility was calculated as follows
TIDC = 1 − TCal
where, TIDC and TCaI represent the true ileal digestibility and true ileal indigestibility coefficients of Ca, respectively.
