Farming of the Future

So over the past 50 years, farming has changed drastically. On dairy farms, you had to milk the cow by hand, leave the milk just in a bottle, and you would have to take it someone right away so it wouldnt go bad. You also probably did not have that many cows on your farm, because it was alot to handle. It was mostly your family working for you too.
Now there are many new ways to make farm work more efficient.
There are machines now that you can hook up to a cow's udder and it will extract the milk from the udder instead of doing it by hand. This saves time because it will suck the milk into a large tank, instead of having the person put it in a small bucket, then having to leave and get new buckets and empty it. This tank also keeps the milk cold, and refridgerated.
I have friend, lets call him Neil Thomas Kruse. He lives on his family's dairy farm. It has been in their family for 3 generations. They sometimes milk the cows by hand, because they have 200, and do not have that many machines. Himself and his brothers have to work on their farm.
All of his 200 cows are girls. They have to artificially inseminate the cows, because they do not own any male cows, aka bulls.
The milk the cows produce, they sell to many dairy companies, so they can pasturize it. But Neil does drink the milk when it is unpasturized, and he says it is much better that way.
They feed the cows hay and grass, which is what all cows eat.
Neil tells me that he has never had a cow with mad cow disease. Which is usually caused when you feed cows the remains of other cows, to save money instead of buying them food.
As you can see, there are many new farmers techniques, and there will be many more in the future. These new techniques
