feeding synthetic and herbal choline on broiler performance

Herbal substitutes of choline have been found to be unable to replace synthetic choline wholely from poultry diets. This is primarily because choline has both structural and functional role. The structural role of choline in the body of the animal is one which cannot be done by functional mimics like the herbal alternatives.
To give an analogy, take the example of sweetners, sugar is the real thing and is necessary in all structural carbohydrates because of its 6 carbon ring but sweetners can replace much of the sweetening needs of sugar. But if your diet is hypoglycaemic, you cannot avoid sugar and expect same performance.
Breeding companies give clear guidelines as to how much choline should be present in the diet but very often farmers and feed manufacturers are found offering twice as much of choline and getting benefits. this is because of the functional role of choline which includes methionine replacement. at that level, choline methionine and betaine are almost interchangeable in the poultry diet.
this is also the scope of the herbal mimic because some choline some methionine and may be some betaine (if the farmer does use betaine) can be replaced in the feed by using herbal alternatives provided it is economically feasible.

wow nice article , ayurvedic or herbal for broiler a new domension good author for your new addition

I agree with Dr Mrinal

The manner in which trial is conducted renders the given information useless and futile
It is not mentioned that, at what dose, the synthetic choline is added
It is also not mentioned what is the dose of added essential amino acids specially methoine, which has great bearing on out come of trial. Even in mentioned formualtion there is no space left for the same

Such product does not find their places in mature market like EU or US where it is mendatory to show what is the active ingredient, mechanism of action, repeatability, traceability so on and so forth.
