Dear Shahzaib Shakeel, thanks for your question. It is essential to calculate the amino acid supplementation on the basis of the metabolizable methionine or lysine content. The mMet content of Mepron is 612g/kg. If we used another product with the same mMet content, we supplemented the same grams of that product as we used Mepron and got the same result. With products lower in mMet content than Me ...

Methionine has many metabolic roles, so it is not just protein in milk. In any case if you are interested in raising your milk protein you have to consider also the metabolizable Lysine, the rapport between metabolizable Lys and metabolizable Met and the quantity of metabolizable Lys & Met /Mcal ME.A rough guideline would be a % over total metabolizable protein of 6,8-7% Lys and 2.40-2,70% Met ...

Abdul Qader Samsor Yes, the genetic potential for milk yield and for components is different for the different breeds. Holsteins cows have lower milk fat and milk protein than Jersey cows for example. The requirement for nutrients depends on the breed (and within breed on milk yield, milk components, DIM and so on). Optimizing rations for nutrients means to optimize the nutrient supply from fee ...

Branko Stuburic Nitrogen emissions contribute substantially to the carbon footprint of dairy farms. N2O is the most potent greenhouse gas (265 CO2 equivalents), higher than methane (28 CO2 equivalents). Optimizing the amino acids supply with methionine from Mepron and reducing the dietary CP level leads to increased nitrogen efficiency (milk protein N per N intake) and lower N emissions and low ...

Shahzaib Shakeel One half of DL-methionine is already L-methionine. D-methionine is transformed to L but at a slow rate so that the D-form acts as a potential reservoir for L-Met.The downside of using an analogue is that it is not methionine. It needs to be converted to methionine which consumes energy which is a downside on particular under heat stress conditions. The analogue is a 50:50 mixture ...

Hi Joe, Yes, every time more metabolic roles for methionine are discovered. Considering methionine just as a tool to improve milk protein yield is quite outdated...

Hazem Hassanien The pure product is costly per kg. As Mepron supplies methionine in a highly concentrated form (85% DL-methionine), it helps covering the first limiting amino acid without using high amounts of protein feeds that are more expensive per unit of methionine. In addition, it helps to reduce the nitrogen load and to improve the nitrogen efficiency. As total feed costs are reduced with ...

Many European dairy farmers suffered a lot from the bad milk price situation in the past few years. Fortunately, prices have stabilized over the last two years and farmers look to continue to be profitable. Nonetheless, a more volatile price situation for dairy products is expected for the future. With feed costs representing the largest input in cost of production, it is of high importance to use ...
