I was wondering how companies distinguish how much fat, saturated fats, trans fat, protien, vitamins, cholestorol in the food we buy. I could understand some products like Ice Cream but how do they know that in milk or meat that there is specifcally like 14g of protein and 14mg of calcium.

Since most things are made with a consistent recipes (even the cows are fed the same thing everyday) they are able to take an average reading. Numbers are obtained sometimes by simply knowing how much was added in, or by running specific assays for each nutrient (bomb calorimetry, acid digestion/spectrometry, ether extraction, HPLC).
Bomb calorimetry is the most fun b/c you get to blow stuff up to find out how many calories are in it. We were goofing off at work one day and decided to check the value Cheeto's printed on their bag, it was right on the money!

I believe they use estimates and averages. Good question, though.
