Is the effect of passing through rumen amino acids and choline really?

Now there are many rumen products on the market, such as methionine, lysine, choline, the price is very expensive, promotional materials are well written, I would like to ask Mr. Lu, is the effect of these products really? In theory, the key to the effectiveness of rumen products is the process and the amount of addition, as well as the composition of the formula-- yes, the amount of addition in different periods. Different-- effective! But it depends on the diet composition. 2} 3]% C9d4K'o also depends on whether it is a real rumen product. 3c + L! {5y; ^ * E'p2r9o0f "Z in fact, there are not many rumen products that really pass the border. Take methionine, for example, there are only a few in the whole world. However, the rumen-passing technique of lysine is not very optimistic. 1?. At the same time, some studies have proved that some methionine analogues can produce positive benefits, but their mechanism has nothing to do with the supply of rumen amino acids. Its function is only to change the rumen fermentation pattern and stimulate the growth of rumen microorganisms. -- effective! But it depends on the diet composition.) J. Z + ^.

I've done experiments in this area-- it's effective in theory, but it depends on the quality of the product-- it should be effective. There have also been experiments in this area-the amino acids that pass through the stomach, choline, are useful, but whether such a product is used or not has something to do with the structure and thinking of your formula.)

Can you talk about some indicators and economy of use-- can you list some products? I can see from foreign materials that Sturmin of Andy Su and mepron of Degusai are all right. Is mepron a coated product? if it is put into production and it is economical. It's better to wrap it in fat powder-it works. It's good to wrap it with resin.
