An analytic method to evaluate performance of lactating animals by use of a parameterized algebraic model based on hypotheses about the physiology of lactation. Observed production data are fitted to the model to generate a set of parameter values which optimize compliance between model and data. Fitted parameter values summarize the lactation production of the animal or group. Inferences can be made from the fitted parameter values by referring to the physiologic assumptions made in deriving the model, and from their relationship with global or localized standards. Inferences can be used in managing health and productivity of the individual or group, for the development and testing of products which influence the health and productivity of lactating animals, and for evaluating genotype of animals or environmental conditions. Parameter values can be used recursively to improve the fitting process.
