Abstract

One of the most important aspects of livestock is the supply of essential quantities of balanced nutrients manufacture. In several physiological functions of nutrients, concerning organisms, protein has an important role. Ruminants are not wholly protected of amino acids by microflora degradation of animal feed sources and by maintaining proteins from the breakdown in the rumen where both high and medium yielding ruminant amino acids are required, they must be met; therefore, rumen-protected protein (RPP) dietary supplementation, including primarily rumen-protected protein (RPP), methionine (RPMeth), protected from rumen flora, it was necessary. Numerous scientists are attracted in the study of the character of (RPMeth) in a dairy cow about it’s an impact on milk produce, growth rate, N- efficiency, coefficient digestibility, intake of DM. Unluckily, the findings obtained from many RPMeth investigations showed excessive fluctuation results in ruminant nutrition between its helpful and useless influence, specifically during early and late lactation periods. Thus, for ruminants, when they use this review post, farm owners may be careful when they are plan to apply RPMeth to the diet of animals. In summary, supplementation RPMeth also has a positive balanced effect, even with no detrimental effect on the yield of milk, animal productivity and hemato-biochemical parameters, especially during the early lactation when used with a ruminant diet low in crude protein.
