Özet
In this study, milk of healthy 20 goats in the 3rd-4thlactation periods was analyzed in different lactation stages. While milk pH, fat, fat-free dry matter, protein, lactose and freezing point were similar between groups in all lactation stages, electrical conductivity and Somatic Cell Count (SCC) increased with the continuation of lactation (P<0.05; P<0.001). Nonspecific relations were found between SCC and electrical conductivity in mastitis-free goats. Also, correlations were found between milk quality parameters and different lactation stages at the significant levels (P<0.05, P<0.01). There was a positive correlation between SCC and milk fat in early lactation (r=0.619; P<0.05). On the other hand, a negative correlation was found between freezing point and electrical conductivity in the late lactation (r=-0.474; P<0.05). It was understood that milk composition and especially SCC values were different in different stag-es of lactation in Damascus goats.The relationship between the components of milk was found to be related to the lactation period. As a result, while the chemical composition of milk did not change during the lactation, it was conclud-ed that the milk produced in the early lactation had lower SCC and electrical conductivity values than in the other lacta-tion stages, and the milk produced in early lactation stage was higher quality.
