In an attempt to improve the quality of cow milk, milk from thirty cows was assessed before and after a controlled dietary and hormonal regime over eight weeks. A control group of thirty cows kept under the usual regime was also included.
The `milk_cows` data set provides the complete before/after milk composition data for the sixty cows, with the proportions of protein (`pr`), milk fat (`mf`), carbohydrate (`ch`), calcium (`Ca`), sodium (`Na`), and potassium (`K`).
