Minimize Condemnations: Protect Profits Through Supplementation of HMTBa

Published on: 11/01/2017
Author/s : Fenglan Yan, Ph.D., Research Sr. Scientist, Poultry Nutrition – Novus International, Inc.

Recent data has shown broilers supplemented with HMTBa (2-hydroxy 4-(methylthio) butanoic acid) as a methionine source exhibited fewer condemnations and higher livability consistently. Broiler producers know that to achieve their best profit margins, every aspect of the process from live production to processing must be optimized, but many producers find that even through careful management, conde...

What is a mechanism of this result?
And what are the kinds of condemnation that be reduced?
What is the amount of HMTBa be used in the ration?

Thank you for your interest in my article, Mr. Trakullerswilai.

As I mentioned, the data presented here is from an independent industry benchmarking organization representing majority of broilers raised in the U.S. during the period. It was not a new study, and there were no measurements made to understand the mechanism of action.

HMTBa is an organic acid before its conversion to methionine in vivo, but is commonly referred to as a source of methionine. From our decades of research, we believe the benefits come from the unique organic acid properties of HMTBa – antibacterial, anti-mold and antioxidant – exerting its benefits both in feed and in animals leading to better overall health.

As for kinds of condemnations reduced, among the total reduction in condemnations, 35% were from airsacculitis, 32% from parts condemnation, 14.2% from septicaemia/toxaemia, 17% from inflammatory process and the remaining from leukemia, bruises and others. The reports did not include the exact amount of HMTBa, but the typical inclusion rate for ALIMET® feed supplement (source of HMTBa containing 88% HMTBa) is 0.15 to 0.30% in broiler diets targeting specific dietary digestible total sulfur amino acid concentrations to meet birds’ requirement at a given age.

If you have additional questions about the ALIMET feed supplement that uses this HMTBa molecule, please submit your inquiry at the link below to be connected with our sales and technical services team for Southeast Asia.

Some Thoughts...

Broiler Condemnations

Yes, HMTBa is an organic acid; but so is methionine (an amino acid, clue is in the name…). Being an acid does not imply easier absorption. Independent studies show NO HMTBa activity against a range of bacteria and moulds, and little or no impact on gut pH.

Different Acids, Different Results

We have no reason to dispute the numbers of birds fed on either DL Methionine or HMTBa. We also agree with the statement “each has a different chemical structure which affects the end result of supplementation in performance”; however, our long term research on the impact of the different sources of methionine clearly shows that DL Methionine is superior to HTMBa.

The basic problem with this article is that it uses data from a source with no control at all. Different feeds from different companies will vary in terms of energy; other amino acids; Calcium; Phosphorus; etc. Then we need to consider the variance in age to which the birds are fed; and management of said birds will vary from farm to farm; and that condemnation regimes will vary from state to state, plant to plant. Finally, the author does not even have data on inclusion levels of different methionine sources.

In other words, the ONLY correct way to compare performance of birds fed EITHER DL Methionine OR HTMBa is to carry out a trial where all the above factors are controlled ie kept the same, so that any difference CAN ONLY BE caused by the different M+C source.

Both figures presented try to correlate a difference in profitability / livability of broilers with a methionine source. Because of the differing environments discussed above, this correlation is not correct; for other examples of this kind of “poor science” one should look at http://tylervigen.com/spurious-correlations
