Mike Persia (Virginia Tech University) commented on his research on the most effective dose of butyric acid fed to broilers, and when it is better to do it, during IPPE 2018 in Atlanta, USA.

Dear Mike,

Thank you so much for your idea but can you please tell me what do you mean by lower doses in small ages and higher doses at old ages (what is lower and higher in figures?).

Regards.

Dear Mike,
You mentioned the commercial doses. But they actually differ from product to product btw 0.5-3kg/ton feed. Can you recommend a narrower range according to diff types of BA?
Regards.

Based on our experience, for broilers, if you're using Adimix Precision (a target release, precision delivered butyric acid) for booster stage(Day 1 to 10),1 Kilogram Of Adimix Precision per Ton of Booster feeds, for grower stage(Day 11 to 20) we recommend 500 grams of Adimix Precision per Ton of Feed of Grower Feed and in the Finisher (Day 21 to harvest) it’s best to use still 500grams of Adimix Precision per Ton of finisher Feed or as low as 250 grams of Adimix Precision per ton of finisher feeds.

Can you be more specific in Indian condition, Sir? 
1 to 10 days 11 to 24 days and 25 to 36 days, please.

Harish Murty: in principle, the same. Depending on your feeding program. There is advantage of a high dose (e.g. 1 Kg of Adimix Precision per ton of Feed) in young broilers/pullets from day 1 to day 10 in broilers, or day 1 to week 4 or 5 in replacement pullets. This is to support and stimulate the villi development since Butyrate level is low or none at all in young birds.

Dear Mike,
Interestingly, there are various variants of Butyric Acid salts available commercially, varying in the coating system, varying in the percentage claim of Na-butyrate or Ca-butyrate in the products. Was wondering if you have used butyric acid (pure) or their salts with a coating system. Could you let us know the specs of the Butyric acid you had used?

Sir, can you suggest us best coatings and doses of butyric acid?

What are the differences between the use of butyric acid and its salts as sodium or calcium butyrate and which are the preferable?

Thanks Zead for bringing up the question – this has been haunting me for a very long time.

From the Chemistry point of View, Calcium Butyrate and Sodium Butyrate has not much difference. For both the pKa is 4.8.
However in many markets, often a sales person with the help of the product managements inputs is tempted to promote the Calcium Butyrate by saying Calcium is bivalent hence releases 2 butyric ion when compared against 1 butyric ion released from Sodium Butyrate ( Sodium being Monovalent). Unfortunately from Chemistry point of view this is certainly a misleading claim. Let us see why ?

Molecular Weight of Calcium Butyrate = 214.274 g/mol
Atomic weight of Calcium = 40.078 g/mol
Available Butyric Ion / mol of Ca-butyrate = 214.274 – 40.078 = 174.96 g/mol.
Number of Butyric Ions available In 1000 gms of ( 100% pure) Calcium Butyrate = 1000/ 214.274 = 4.6 mols
Available Butyric Ion present in 4.6 mol of Ca-butyrate = 4.6 X 174.96 = 804.816 gms.

Molecular Weight of Sodium Butyrate = 110.088 g/mol
Atomic weight of Sodium = 22.99 g/mol
Available Butyric Ion / mol of Na-butyrate = 110.088 – 22.99 = 87.098 g/mol.
Number of Butyric Ions available In 1000 gms of ( 100% pure) Sodium Butyrate = 1000/ 110.088 = 9.08 mols
Available Butyric Ion present in 9.08 mol of Na-butyrate = 9.08 X 87.098 = 797.36 gms.

So the difference of butyric ion released by 1000 gm of Calcium butyrate is just about 7.456 gms which is perhaps not very significant while considering the fact that the Ionisation potential of Sodium is 11 eV while Calcium is 20 eV. Which means Sodium butyrate will dissotiate much faster almost at double the rate of Calcium Butyrate, with lower energy requirement.

Keeping the above in view there is no much difference in terms of Sodium Butyrate and Calcium Butyrate salt Chemistry and both are almost similar.

The twist in the story comes when we consider the coating system. Two most prevalent coating systems available in the market are:
1) Hydrogenated Vegetable Fat
2) Glyco mono Sterate (GMS)

GMS can be broken down only by Pancreatic Lipase and perhaps provides a better protection of the Butyric Salt in the fore-gut ( by providing a Fore-gut Bypass kind of a mechanism), which enables and ensures release of the Butyric Ion in the Midgut and Hind Gut area which is desirable.

Saying so Hydrogenated Vegetable Fat coating ( with various innovative terms like matrix coated, matrix encapsulated etc. etc. ) perhaps would provide reasonable efficiency as well.

What I find more confusing is the concentration of Butyric Salt is different in various brands offering 30% onwards, and potentially another factor that should be looked into, while choosing a product and its dose.

Would be happy to know more on the above – as there is lots of confusion regarding the claims made by various commercially available brands in the market which hovers around the percentage availability of the Salt, its coating material and technology and offcourse weather it’s a Sodium Salt or a Calcium Salt.

oops Apologies. The Ionisation potential of Na is 5.139 while that of Calcium is 6.113 eV. Sorry for the mistake

Appreciable comments from Mr. Goswami,
Also there is purity issue come for butyric acid,
Fermented butyric acid I heard that is much better than normal Avilable butyric acid, fermented shown. Higher Bioavilability and also no heavy metal finding..
Synthetic material like CMC which are also used in coating in pharma industry are now using..

I still having doubt on all facts, plz explain

Yeah, I found at least 1 patent that was applied for with cmc as coating material while searching google. I ain't sure but it appears it was later withdrawn (EP20090767981).
Any comments from the experts in the group will help us get further enlightened.

How many part per million is in finished ton of feed?

Difficult question!
I have found companies suggesting as low as 250 gm / mt for some brands while few recommending 1 kg / mt while few others recommending 2 kg or even 3 kg per mt in poultry.
I am convinced that I am now totally confused on the dose recomendation. Perhaps you should enquire with the producer of the particular brand. I wish i could have been more helpful
