Variations in the milk yield and milk composition of a dairy cow colony (n = 23) were analyzed during 11 months of lactation. Milk yield followed a characteristic decreasing pattern in negative correlations with solid components (milk protein, lactose, total solids, milk fat). Titrable acidity (degree SH) was significantly (p < 0.1) higher in the milk of fresh-milking cows and it correlated negatively with lactose and positively with milk protein, milk fat and total solids. The concentrations of Zn, Fe and Cu tended to decrease, while Mn showed insignificant variation during lactation. Milk vitamin A showed a significant positive whilst milk vitamin E had a negative correlation with milk fat.
在泌乳的11个月期间，分析了一个奶牛群体（n = 23）的产奶量和乳成分变化。产奶量呈现出特征性的下降模式，与固体成分（乳蛋白、乳糖、总固体、乳脂肪）呈负相关。刚挤奶的奶牛所产牛奶的可滴定酸度（SH度）显著更高（p < 0.1），且与乳糖呈负相关，与乳蛋白、乳脂肪和总固体呈正相关。锌、铁和铜的浓度趋于下降，而锰在泌乳期间变化不显著。乳维生素A与乳脂肪呈显著正相关，而乳维生素E与乳脂肪呈负相关。
