DÜZCE'DE YETİŞTİRİLEN ANADOLU IRKI MANDA SÜTLERİNDE LAKTASYON BOYUNCA MEYDANA GELEN DEĞİŞMELER.

In this study, changes in some physico-chemical properties of Anatolian buffalo milk during lactation were investigated. The study was carried out on 30 Anatolian buffalos and 462 milk samples were analyzed. As a result, the general average dry matter value of buffalo milk samples analized was 15.74%, fat content 6.49%, protein 4.30%, milk salts 0.77%, lactose 5.40%, pH 6.72, specific gravity 1.030, freezing point -0.62°C, electrical conductivity 2.73 mS/cm and somatic cell count 152760 cells/mL. Dry matter values of the samples were higher at the end of lactation (P <0.05). The highest fat value was observed in September and October (P <0.05). Lactose values were high in July. Specific gravity ranged from 1.029 to 1.033. The conductivity values increased up to 2.95 mS/cm in August. Freezing point values decreased until July and increased in the following months (P <0.05). Somatic cell counts were highest in May (P <0.05). [ABSTRACT FROM AUTHOR]
