Milk composition is economically important to milk producers and processors and nutritionally important to consumers. It has been known for years that variations in milk composition occur; however, the composition of milk marketed nationally has been rather constant over the last 15 years, averaging 3.6 percent fat, 3.2 percent protein, and 4.7 percent lactose (Young et al., 1986).

Apr 1, 2006 · This paper will review the major scientific advances in manipulation of milk composition over the last 25 yr. A multitude of factors influence the final composition of milk including genetics and breed of animal, environment, stage of lactation, parity, and nutrition of the cow. Although all of these factors work in combination to determine the ...

May 5, 2021 · The differences in gross milk composition observed among cow breeds are of considerably greater magnitude than those which can be achieved through dietary interventions and, although genetic effects are the primary determinants of the AA composition of proteins, changes to cow diets nonetheless have a notable influence on concentrations of gross milk proteins and can be more readily altered by ...

Milk Proteins. Plant Oils. Lactose. A number of major scientific advances have been realized in the last 25 yr in determining the opportunities and limitations of altering milk composition through nutritional manipulation. Because of the greater sensitivity of milk fat to dietary manipulation than either protein or lactose, nutritiona ….
