Sažetak
The aim of research was to determine the influence of stages of lactation on the chemical composition and physical properties of sheep milk. The analysis involved a total of 202 milk samples in various strages of lactation (beginning, midpoint, end). Milk analyses included determination of the content of dry matter, fat, protein, lactose, solids-non-fat, degree of acidity, pH values and freezing point. Data was statistically processed in accordance with the SAS statistics package )1996). Sheep milk contained on average 19.11% total solids, 7.52% fat, 5.90% protein, 4.55% lactose, 11.45% solids-non-fat. Titratable acidity of milk amounted to 9, 30°SH, ionometric 6.78, and freezing point was &#8211; 0.566°C. In the middle and at the and of the lactation period the contents of total solids, fat, protein, and pH value were significantly higher (P<0.01) than at the beginning. In the same period lactose content and titratable acidity values were significantly lower (P<0.01).
