Comparative liquid methionine and powder methionine on performance of broilers.
Please outline the benefits of doing that.
I see a lot of drawbacks; to name a few, you need extra equipment and you add organic material to the water system, thus promoting growth of microorganisms and algae in the watersystem especially at the high temperatures at the start.
Furthermore you can not ensure similar administration of the methionine to all birds, as the food to water consumption ratio will differ considerably between animals, thus probably reducing uniformity of the flock.
Thanks for your answering C.A. (Kees) Kan. But my mind was to use of this ingredient in diet of broiler. You think, we could not use of this source of methionine in stand of powder form?
To ensure even distribution of a rather small amount of liquid (to keep your diet dry enough from preventing mould growth) you need either very good equipment or quite long procedures or mixing times. You might also spray it on the pellets but also then equipment and accuracy to evenly distribute a rather expensive ingrediënt might be quite a challenge.
Hi Mahmood,As I red in some papers, You couldn't substitute completely LMet instead of PMet. but the best results had been for 1/3 substitution.
Thanks for your answering Mohammad Reza.
Could you send to me that papers?

I support C.A. (Kees) Kan. There are a lot of drawbacks in distribution uniformly of liquid methionine. It needs equipments, care and time. Spray may be another option but it also needs very care.
Dear Mahmood
Relative effectiveness of liquid MHA-FA relative to DLM is about 64%. Since economic aspects of its substitution to DLM should be considered.
Regarding this, you can have a look on attached papers
Cheers

Dear Mahmood,
Refer to the paper in the link below. It gives you a detailed pros and cons as regards to solid vs liquid asdditives including methionine. http://www.academia.edu/4411889/Dosing_Handling_of_Solid_vs_liquid_additives

If you use liquid methionine in molecular basis which is 1.120 = 1 is effective as powder methionine, but it needs equipments . First it is recommended for feed manufacturing and they have to install equipments to spray it precisely and aquiratly. It is difficult for those who want to make feed by themselves otherwise have equipments. It should be used in drinking water whenever methionine deficiency is present. It's price is lower than powder methionine which 1.12 kg is cheaper than 1 kg powder methionine and it also has acidic power which help gut health and eliminate use of acidic compounds therfore lower feed costs. Finally it is recommended for poultry feed manufacturers first.
In some experiments which have been carried out to evaluate the efficacy of liquid methionine they have not used enough treatments and levels which can reach an accurate conclusion but I think it can be used as an alternative for powder methionine e if it's price be lower than powder.
