Recent publications by Verhelle und Saremi (2024) and Westreicher-Kristen et al. (2025) reported broiler feeding experiments to evaluate the nutritional value of guanidinoacetic acid (GAA) in comparison to L-arginine (L-Arg). Basically, reported broiler performance responses are in agreement with expectations based on literature. However, the authors drew misleading conclusions on the efficacy of ...

Compilation of a projectKEY INFORMATIONA series of 5 commercial feeding trials was performed from which 4 trials took place on commercial broiler farms growing between 300,000 and 420,000 broilers per cycle.Dietary protein was gradually reduced in subsequent trial while standard diets well represented German broiler feed. Basically, average crude protein levels were decreased by 0.3 % up to 1.5 %. ...

Yes, DL- Methionine can replace methionine hydroxy analogue in the ratio of 65: 100 in broiler chickens feed without any adverse effect in any of the production indicators. I , myself have conducted several experiments replacing DL- methionine with MHA. If we increase the replacement level of MHA, the production performance is significantly reduced.

@Dr. Rajendra Prasad Vemana I really do not agree with this very "broad brush" description. If I consider that sNSP content of maize is only 20% that of wheat, I cannot see in any way that an enzyme that MIGHT contribute 100 kcal energy sparing in a wheat-based diet can provide anything close to 100 kcal in a maize-based diet - simply not enough substrate! I would use 20 - 30 kcal maximum such die ...

Dear Alireza, thank you for confirming the concept by an additional data set. I like to pronounce, that validating the equivalency of DL-Met and the methionine hydroxy analogue at 65:100 replacement ratio not only results in same animal performance but also in considerable cost savings when using DL-Met provided the price ratio between mentioned products is not 65%, which means the price of the hy ...

there is nice report.
We replaced in diet 65 part of DL-MET with 100 part of MHA in trial on 6000 broilers in iran. Results indicated that body weight and FCR were the same in both groups confirming 65% RBV of MHA.

Hello. Interesting concept, that feeds would require supplementation with liquid amino acids. First, may I clarify one small point. For every amino acid other than methionine, the content of liquid products can be directly compared to solid versions; so a 50% lysine liquid will supply 500 mg lysine per g consumed. For lysine hydrochloride the value is 78% / 780 mg / g. Therefore to replace 1 g lys ...
