Changes in dry matter content, protein, fat, lactose and pH were followed in five goats of the Brown Short-haired breed in the second and/or subsequent lactation. Analyses were carried out from 2 to 72 hours after parturition. Within this interval, the content of dry matter decreased from 23.83 to 16.03 %. Contents of crude protein, true protein, whey protein and fat dropped from 13.47 to 5.38 g/100 ml, from 12.24 to 5.12 g/100 ml, from 8.93 to 1.57 g/100 ml and from 7.52 to 5.26 g/100 ml, respectively. The content of casein increased from 0.98 to 3.55 g/100 ml and that of lactose from 2.80 to 4.20 g/100 ml. The values of pH fluctuated from 6.28 to 6.59. Dependencies of mean values of the nutritional parameters under study on the postpartum time interval were evaluated by means of regression analysis.
