Milk composition study


In an attempt to improve the quality of cow milk, milk from each of thirty cows was assessed by dietary composition before and after a strictly controlled dietary and hormonal regime over a period of eight weeks. Although seasonal variations in milk quality might have been regarded as negligible over this period, it was decided to have a control group of thirty cows kept under the same conditions but on a regular established regime. The sixty cows were of course allocated to control and treatment groups at random. The 'milk_cows' data set provides the complete set of before and after milk compositions for the sixty cows, showing the protein (pr), milk fat (mf), carbohydrate (ch), calcium (Ca), sodium (Na) and potassium (K) proportions by weight of total dietary content.
