L. F. Brito, Silva, F. G., Melo, A. L. P., Caetano, G. C., Torres, R. A., Rodrigues, M. T., and Menezes, G. R. O., Genetic and environmental factors that influence production and quality of milk of Alpine and Saanen goats, vol. 10, pp. 3794-3802, 2011.

Data from 1279 lactations of 783 Alpine and Saanen goats of the herd of our university in Minas Gerais, Brazil, were used to study environmental effects on and to estimate genetic parameters for milk production until 270 days of lactation (MP270) and for production and percentages of fat (PFAT and %FAT), protein (PPROT and %PROT), lactose (PLACT and %LACT), and total dry extract (PEXTR and %EXTR). Environmental effects were estimated by a statistical model that included contemporary group effect, type of kidding, genetic grouping, and kidding order.
