In my humble opinion I would say adequate Methionine + 960-1440 mg betaine /kg of feed. Mostly it would depend on what the goal is. But maybe someone has had different results or experiences they could share?

Dr. Fiodor S. Marchenkov We recommend up to 2.5 Kg betaine HCl or approximately 2 Kg betaine anhydrous per ton. This helps achieve maximal cellular betaine concentration to allow this molecule to maintain optimal recycling of homocysteine back to methionine while at the same time provides optimum cellular osmotic maintenance to maximize energy sparing. This energy sparing effect can be used to r ...

Hi Ana, Most of our customers is laying commercial farm and still using cage with open house system. Dosage for betain hcl is 1 kg per ton of feed without any put choline chloride. They also use around 2.0 to 2.2 kg of dl-methionine per ton of feed. Regards.

Desra Eri Dr.Eri, thanks for your comments. I know in Saudi Arabia use 2 kg/t feed of betaine for broilers, to prevent overheating. Also, it is important betaine less fat and more meat effect in broiler fattening.

Dear All, Very interesting discussion. We do here in Indonesia as tropical country. With 1 kg of Betain per ton of feed and having a good result to help the bird for control of heat stress. Regards. Dr. Eri Desra

Great discussion. These types of discussions helps everyone. There is always something to learn !! Thanks Mark Farmer, Ph.D. Diamond V

Dear all,As stated by Dr. Waldroup his team had published several papers around 2005 and 2006 related with methionine savings and the possible sparing effects of methyl donors like choline and or betaine.All the above comments are right; but, maybe there is little space emphasizing that betaine due to its zwitterionic structure has very strong osmoprotective properties.As an example protecting int ...

Dear Park W. Waldroup, thank you for your comment! I want to add, that the best practical demonstration regarding the methyl group donor function of betaine, respectively methionine replacement, is the European organic farming where the synthetic amino acids are not an option because are not allowed by regulation (are not GMO-free). As nutritionist, I do not agree because the organic livestock nee ...

We have extensively researched the relationship between betaine methionine and choline and at normal usage levels cannot recommended any sparing effect of betaine. However, it does aid in maintaining intestinal integrity and some studies have shown increased breast meat yield.
