Chemical Composition and Physical Properties of Milk in Norduz Sheep

Öz

The objective of this study was to uncover the milk composition traits of Norduz sheep, which are bred in the Gürpınar district of the Van province, during the mid-term lactation period. The chosen ewes exhibited no signs of clinical or subclinical mastitis. A total of 104 sheep milk samples were meticulously collected to undergo comprehensive milk composition analysis. The chemical and physical attributes of Norduz sheep milk were methodically determined utilizing a milk autoanalyzer. The mean values for various milk constituents were as follows: milk fat (%), 2.48±0.11; solids-not-fat (SNF) (%), 10.76±0.08; milk protein (%), 5.09±0.04; lactose (%), 4.79±0.04; pH, 6.93±0.02; conductivity (mS/cm), 4.41±0.04; freezing point (°C), -0.602±0.80; salt (%), 0.8035±0.66; and density (kg/m3), 1039.73±0.39. Noteworthy negative and statistically significant correlations were observed between milk fat and protein (r=-0.36, p<0.001), milk fat and SNF (r=-0.32, p<0.001), as well as milk fat and lactose (r=-0.36, p<0.001). Conversely, positive and significant correlations emerged between SNF and milk protein (r=0.90, p<0.001), SNF and salt (r=0.87, p<0.001), and SNF and lactose (r=0.90, p<0.001). In summation, the protein content of Norduz sheep's milk exceeded that of the majority of sheep breeds reared in Türkiye. These findings carry the potential to make a valuable contribution to enhancing the milk composition of Norduz sheep.
