Careful friends will notice that imported milk has a slightly yellowish color, similar tosoy milk.In contrast, the color of domestic milk is snow-white.This is because the normal color of human breast milk is also slightly yellowish, so some people believe that the white color of domestic milk is due to the use of antibiotics on domestic cows.In reality, the color of milk is related to the season and the feed given to the cows, but it has nothing to do with whether the cows are given antibiotics.According to a farmer who raises cows, the color of the milk, whether it is yellowish or white, is largely related to what the cows eat. Cows fed with feed produce milk with a slightly whitish color, while cows fed with pasture produce milk with a slightly yellowish color.

The color of milk also changes with the season. In summer, cows can eat pasture and vegetables rich in carrots

and lutein, at which time the milk produced will also be yellowish.

In winter, when cows can no longer eat these pastures and vegetables, the milk produced becomes milky white.Fresh milk contains about 3% to 4% fat, which is mainly yellowbutter.If the proportion of butter in milk is high, the milk will naturally be yellowish in color, and the yellow color of the butter comes from

carrotsand lutein.Therefore, the yellowish color of imported milk is due to the fact that they mainly feed their cows with pasture and vegetables rich in carrotsand lutein, which produces milk with a higher fat content.The white color of domestic milk is therefore self-evident.

Therefore, it can be inferred that the reason imported milk turns yellow is that the cows are mainly fed with pastures and vegetables rich in carotene and lutein, resulting in milk with higher fat content.So, the reason for domestic milk being white is self-evident.
