The composition of bulk milk of 18 herds of ewes and 14 herds of goats and the milk of 10 individual animals of each ewes and goats during a 12 weeks lactation period was studied. The average percentage of acidity of bulk ewe's milk (0.22), fat (6.4), lactose (4.3), total nitrogen (0.9) calcium (0.169), ash (0.940) and total solids (18.6) were higher than 0.17, 4.0, 3.9, 0.62, 0.130, 0.81 and 12.8 of bulk goat's milk. Phosphorus (0.074) was almost similar to (0.077), while non-protein nitrogen (0.0022) was about thirteen times lower than 0.028 of goat's milk. Determined parameters increased, whereas lactose and non-protein nitrogen decreased with progression of the lactation period. Individual ewe's milk occasionally contained 1.4% fat and 0.56% total nitrogen closely resembling individual goat's milk.
对18群母羊和14群山羊的混合奶以及每群母羊和山羊中10只个体动物在12周泌乳期内的奶的成分进行了研究。母羊混合奶的平均酸度（0.22）、脂肪（6.4）、乳糖（4.3）、总氮（0.9）、钙（0.169）、灰分（0.940）和总固体（18.6）百分比高于山羊混合奶的0.17、4.0、3.9、0.62、0.130、0.81和12.8。磷（0.074）与山羊混合奶的磷（0.077）几乎相似，而非蛋白氮（0.0022）比山羊奶的0.028低约13倍。随着泌乳期的推进，所测定的参数增加，而乳糖和非蛋白氮减少。个别母羊的奶偶尔含有1.4%的脂肪和0.56%的总氮，与个别山羊的奶非常相似。
