Analysis of the physical-chemical properties of the milk collected from Jersey and Simmental cows
reveals that the protein and fat contents in the milk produced by Jersey cows are higher by 0.6%, and 1.23% respectively.
Also, the weight content of casein is different. Jersey milk is the richest in casein content.
It contains 0.55% more casein than the milk of Simmental cows (Table 1).
Also, the Jersey cows slightly surpassed the Simmental cows in the density indices and contents of nonfat milk solids
and minerals.
