A study was carried out to establish milk production and composition of the 119 lactating goat from Bulgarian white dairy breed at different lactation.Individual milk samples of goats were taken four times during the lactation period at monthly intervals over a peroid from April to July 1999.Investigated goats have not statistically proved differences (P<0.05)in milk production at 3.2% fat corrected milk and at 3.0% protein corrected milk.There were found statistically significant differences in the lactose content between second and over second lactation (P<0.05) and no differences were found in the freezing point (P<0.05>.The results for somatic cell count differ statistically between first and over second (P<0.01) and second and over second (P<0.001) lactation respectively.Mean value for fat, protein, lactose, freezing point, total solids, solids non fat and somatic cell for I, II and over lactation were 4.66, 4.35 and 4.49; 2.76, 2.82 and 2.87; 4.25, 4.29 and 4.19; -0.546, -0.547 and -0.547; 12.82, 12.62 and 12.61; 8.15, 8.26 and 8.22; 1 140 000, 1 524 000 and 2 916 000 respectively.The prepared yoghurt was with good quality and normally dynamic of whey separation - 75.2% at 180 min.
