Objective of this review is focus on effect of feeding protected fat and protected protein on milk yield and its composition and how these nutrients are protected. Many researchers in this review investigate that the responses are highly dependent on the type of fat and protein supplement and the stage of lactation. A higher milk response was observed with saturated than with unsaturated fat supplements. Diet with added fat increase milk production compared with a control diet without added fat in cows. Feeding of bypass fat resulted in significant increase in milk yield and Fat Corrected Milk yield particularly in early lactation. The source of Protected fat are (origin (animal, plant, processed or whole oilseeds, calcium salts) and Cereal Grains such as corn, wheat, Barly, oil seeds, sun flower, cotton seed, soybeans and canola). The supplementation of protected protein in the diets of lactating animals increases the milk yield due to proportionate increase in the supply of amino acids to the host postruminally Milk yield in cows fed protected methionine for the whole experimental period was numerically higher than in cows of the other groups. However, the difference was not statistically significant .At the centeral high land of Ethiopia the Treatment of shredded wheat and barley straw with urea, molasses, salt and water prior to feeding is a technology that should be considered . Cows with excessive body tissue mobilisation at this stage may take up to 20 weeks to regain a positive energy balance status.
