摘要：Milks of 220 Saanen x Kilis goats’ were taken during 22 weeks of lactation. Chemical compositions, energy values and mineral contents of goats’ milk samples were determined. As results of the goats’ milk samples analyses, the mean values were determined as 12.12% for dry matter; 3.45% for fat; 3.81% for protein; 4.12% for lactose and 261.5 kj/100g for energy value, 6.86 for pH, 6.71 SH for titratable acidity and 1.031 g/cm3 for specific gravity during lactation. The mineral contents of the samples were similarly found to be 220.5 mg/100g for calcium; 108.8 mg/100g for phosphorus; 153.5 mg/100g for potassium, 20.1 mg/100g for mag¬nesium and 67.5 mg/100g for sodium. Results of the statistical analyses indicated significant lactational effects on the contents of total solids, fat, non-fat dry matter, protein, lactose, energy value, titratable acid-ity, pH, specific gravity (P<0.01) and sodium (P<0.05), but there was no similar effect on the contents of calcium, phosphorus, magnesium and potassium values of goats’ milk (P<0.05).
