A cow eats green grass but how does it give white milk?
Answers
Milk contains no chlorophyll (so no green color) but is an emulsion and a solution of fats, protein, and minerals in water, giving a white appearance, although during certain seasons, if the animal is feeding on fresh lush grass, the cream and especially the butter can take on a slightly more golden hue
Heya!
Answer:
We, human beings eat food and excrete out the harmful substances.
Cows eat grass and give out milk as the grass inside their body is digested and we can also treat it as natural!
In human beings, the food gets digested and the whole process occurs and hormones and many enzymes are released inside our body which we study about.
I am not very particular about this but may be if we study about animals more, we will get to know!
In a nutshell, we can say that it's natural as they eat grass it gets digested and we are able to get milk from her body!
