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.

Excerpt from the Book
2.1. Effect of feeding Dairy cows with protected fat on milk yield
Application of supplements of protected fats and polyenoic fatty acids of vegetable origin in a diet of different age and productive groups of cattle stimulates metabolism in the animals, increases their productivity and improves quality of milk (Pavkovych et al 2015) . Dietary fat, that resists biolysis and biohydrogenation in rumen by rumen microorganisms, but gets digested in lower digestive tract, is known as bypass fat or rumen protected fat (inert fat) ( Naik,2011). Supplementation of fat to pasture based system appears to increase milk production by dairy cows grazing high-quality pastures such as (Perennial rye grass, Red clover, White clover, Alfalfa,in cool season) and Cereal Grains such as corn , wheat , Barly , oil seeds, sun flower, cotton seed, soybeans and canola) (Muller, 2003) and by products of cereal grains and oilseed during feed shortage for lactating cows in Ethiopia ( Hassen A et al 2010). The responses are highly dependent on the type of fat supplement and the stage of lactation.
A higher milk response was observed with saturated than with unsaturated fat supplements . The effect of supplementation of dietary fat on milk and FCM production was related to the degree of saturation of the fat supplement and to the stage of lactation. Supplementation with unsaturated Fatty Acid sources did not significantly increase milk or FCM production where as both parameters were increased by saturated FA supplements.
Summary of Chapters
1.Introduction: This chapter highlights the challenges of meeting the nutritional requirements of high-yielding dairy animals in tropical regions and introduces the potential of protected fat and protein supplements.
2. Literature Review: This section provides a comprehensive analysis of research regarding the impact of protected fats and proteins on milk yield, composition, and the economic benefits associated with these nutritional interventions.
3. Methods of protein protection: This chapter explores various technical methods, including formaldehyde and heat treatment, used to shield dietary proteins from ruminal degradation to enhance nutrient availability.
4.Conclusion: The conclusion summarizes the effectiveness of bypass nutrients in improving milk yield and cow health, while identifying the need for further location-specific research.
5. Recommendation: This chapter outlines practical advice for government bodies and farmers in Ethiopia regarding training and the balanced formulation of dairy diets.
