Stephen Adejoro Dr Please be aware that betaine CANNOT replace methionine. Use of betaine as an osmoregulator is completely correct; and yes, it CAN play a role as a methyl donor. However, methionine is an essential amino acid, and cannot be replaced. When methionine donates methyl groups, it is recycled and so betaine plays no role in replacement. Numerous trials have concluded that partially rep ...

Dr. Amit Kumar Pandey Incorrect sir! Oils are actually BETTER than carbohydrates (CHOs) as an energy source in heat stress conditions This is because heat increment is less for lipids than for CHOs; so the animal produces less internal heat and so reduces risk. Net energy systems recognise this and should be used over AME systems. Further, liver insult is more pronounced when processing CHO energ ...

In any experiment looking at dose response to a single nutrient, all other nutrients need to be maintained at a level where they do not impact on performance parameters being investigated. Obviously if this is not the case, results obtained may be due to deficit of another nutrient, rather than that being studied. In this case, all SID AA levels were maintained at a level expected to be sufficient ...

Alfredo Navarro De Andrade Agree regarding composition of crude protein. However, genetic expression leading to varying amounts of the different proteins found in soyabeans IS influenced by growing conditions as well as strain; therefore there are differences, as we see clearly in our data from AminoDat. I doubt, though, that "organic" growing will have a significant effect on AA composition; and ...

First, may I politely ask you to give credit to Evonik and properly reference the fact that the "conventional" soya data you quote comes from our AminoDat 5.0 raw material database. Your amino acid values are IDENTICAL to those quoted in this data base and so reference should be noted.
You give no data in your paper regarding number of samples in your survey. The AminoDat values are based on 1241 ...

So many questions.
1. Feed spec not shown. Deficient in M+C? Energy levels? Other AAs?
2. No data on FCR, feed intake
3. No explanation of causes of mortality
4. No data on location of trial / environmental conditions
5. I assume there was no statistical analysis possible for a house v house trial
To draw any conclusions from such a poorly reported trial is virtually impossible

Heat stress continues to be a challenge, and any contribution to knowledge is welcomed. However, I would correct some of the points raised recently. Use of methionine sources will inevitably reduce heat stress, as correct formulation to SID amino acids will reduce crude protein content and thus energy expended in excreting excess nitrogen.The choice of methionine source needs to account for this. ...

Dear Dr. Adejoro
A very interesting article. Whilst I am in no doubt that mycotoxins contribute to the on-going problems, one should consider a much wider range of nutritional solutions to really start to make improvements. With our extensive experience in West Africa, we are aware that nutritional knowledge and training needs to be seriously improved. Use of up to date formulation tools / nutrit ...

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.
