From the facebook page, I learned 5 interesting things.
1.The color of butter (June 20)
"The yellow color of butter occurs naturally because of the beta-carotene found in the grass cows eat."
The color of the products reflect food which cows ate. If cows have eat the grass which don't contain the beta-carotene, would we make white-colored butter?

2.The products which milk ie used (May 31)
The picture show how milk is used in easy way to understand. There are many products which were made from milk. For example, cheese, yogurt, cream and butter.
3.The importance of the milk (June 3)

This vintage poster show us the importance of the milk. It implies that the milk is useful to mae good teeth and strong bones, and the milk not only gives us vitality, but also makes us endurance.Already we know, milk is good for our health.
4.The golden birthday lady (May 2)
Even though I know and understand it is "business", it is painful for that we have to kill "useless" cows... I want her not to be killed, but she has to provide the milks constantly in order not to be killed. However, it may become difficult for her because she will be old...

4.The difference between cows (June 15)
Actually, I didn't know the difference between these cows. And I was not able to identify which cows gives us the milk. The cows lives in Gingue Brothers Dairy farm has black and white color; they are dairy cattle.
I write this blog with concentrating with only cows. So this Thursday, when we visit the farm, I'll care about not only cows and milks but also crops!
