Effect of rumen protected fat supplementation on milk yield and its composition: A review
Harish Rohila and Amar Shroha
Role of the bypass fat/RPF (Rumen Protected Fat) in the rations of the high producing dairy animals is very crucial for enhancing the energy density of ration. Dietary fat, that resists lipolysis and bio hydrogenation in rumen by rumen microorganisms, but gets digested in lower digestive tract, is known as bypass fat or rumen protected fat or inert fat. High producing buffaloes in early lactation do not consume sufficient dry matter to support maximal production of milk. Demand for energy is very high during early stage of lactation but supply is not commensurate with demand due physiological stage. It may affects production potential of animal in the whole lactation length resulting in lower milk yield. Rumen protected fat plays an important role as source of energy in the ration of high yielding dairy animals for optimum productivity. So, diets containingrumen protected fat often stimulate increased milk production, milk fat percentage because of increased energy intake, improved efficiency of utilization of energy.
