Micro Encapsulation Technique

How does this relate to chicken feed?

Chicken gut generally contains harmful microbes Like Samonella, E.coli etc. that reduces the performances of poultry (growth in body weight or laying eggs). They multiply in pH range 6.8 or higher. Intestinal pH is generally alkaline. Now, if organic acids like citric acid, butyric acid etc. be micro-encapsulated in any way that can pass stomach encapsulated & the acid be released in the intestinal alkaline pH some away form duodenum, the microbes' growth can be prevented. Organic acids now are being fed to poultry but they exert their action somewhat less than expected because of buffering action of the gut. Previously antibiotics were fed to control this problem. But use of antibiotics in feed is banned in many countries. So, feeding microencapsulated organic acid can be great helpful to poultry industry. Thank You.

Dr. Ul Islam,

Thank you for the clarification. I understand, now how the two are related. I also now understand your interest in producing chicken feed.

Although this is not the chicken feed thread, you might consider an apparatus such as this:

for grinding and extruding the feed products. This might at least be useful in the early stages of your endeavor to produce more healthy chickens.

The picture is from Wikipedia. Good luck.

I hope I have not mis-spelled or somehow not gotten your name correct.

Dear Lynlynch, Thank you very much for good suggestion. I forgot but now remember, When I was a kid in mid 60's, in our family we had a machine like this. That was used to produce very thin noodles like food known as SEMAI (In English possibly it is called vermicellis). At that time its price was nearly 1 US$. Now I think this type of machine can be made some what in larger size from a foundry. In our country a person is called by first name. So, I am Anwar. Syed Md. is my family title. I have searched web for micro-encapsulation but could not find anything fruitful. If you could find anything in this regard, please let me know. Poultry nutrition is interesting to me. Thank you again. Anwar.

Perhaps a search for the release mechanism in lieu of the encapsulation method will get you some better results.

This link is the Wikipedia article for Time Release Technology for drugs. While I have nothing direct to contribute, the attribute of timed release may be more germane than the encapsulation of the product. Chitin may be something to review further.

Best of luck in your search.

Google: entric coatings and entric coating technologies.

Also China manufactures inexpensive meat grinders like the one lynlynch showed you, with a capacity of 600Lbs/Hr.(272.1554Kg/Hr), equipped with a pulley so it can be motorized. : northerntool.com

Enteric coatings... exactly the phrase I could not remember.

I believe you are correct, this is a good subject that may likely help our new member Anwar. GA vote for you.

Thanks Doorman, but it looks like you will have tor retract the GA for my misspelling of enteric.

Ah, we knew what you meant. It's still a GA. I could not remember 'Enteric', or I would have given it up in my post.

CR4 isn't supposed to be a spelling test, it's supposed to be about information.

Just curious: would small but normal sized capsules be about the same size as a food pellet, and would the chickens eat them, or avoid them?

Dear Tornado, These micro-capsules' size are to be fraction of a millimeter (300-400 microns), so that they can be easily be uniformly mixed with the crushed/powdery mixer of the feed ingredients. Chickens will possibly avoid normal size capsules. Even if they do, all the birds will not get them equally. Thanks for your curiosity. Anwar

Hey guys, where did the OP say anything about chickens??

He is relatively new, with 2 threads and ~6 posts. The other thread is about feed pellet manufacture. This one is indirectly related, and several replies are addressing both at once.

Dear Corelite, Only few days ago I found CR4. Actually I don't know much about CR4. But I found that CR4 mainly works on Engineering subjects. So, I asked for a machine which is an engineering subject. CR4 also has a Technologies & research section. So I asked for micro- encapsulation. You may notice that I have not asked anything about chickens. Yet, if you think that I have done this thing wrong, I am very much sorry. Thank you. Anwar

Anwar,

No apology is necessary. I was merely confused by the reference to chickens in the replies to your query; Tornado and lynlynch have cleared it up for me.

Syntol AMD is unlike many of the probiotic products available today. Unlike many probiotic's it is a synbiotic product that provides a combination of both probiotic organisms and prebiotics. Prebiotics beneficially affect the digestive tract by creating the correct environment to stimulate the growth and/or activity of probiotics.

The biggest problem with probiotics is stomach acid and shelf-life. Probiotics are living organisms. Stomach acids kill them off and because they are living organisms they have a short shelf-life. That's why you will find some probiotic products in the refrigerated section of your health food store.

To elevate the shelf-life and stomach acid issue Arthur Andrew Medical have developed a revolutionary process in which the probiotic bacteria have been forced into their spore state. Spores are bacteria that, due to unfavorable growing conditions, dehydrate themselves into a kind of "protective shell" that keeps them save until growing conditions are right.

This keeps the Syntol product well-protected and long-lasting without refrigeration. They remain in this state until the proper conditions are met whereupon they rehydrate and grow and multiply. Syntol ADM is the perfect probiotic and prebiotic product

Dear corelite, I am happy that I have not done this wrong. your suggestion for 'Spore' is valuable. Spore is pro-biotic (also written as probiotic). There are also prebiotics & eubiotics. These are being used in poultry ration since 80's or before. They have drawn much more attention from a decade ago when EU & many other countries (may be USA also) put restriction/banned antibiotic use in poultry & swine feed for food safety reason. Adavnced researches are still going on in many countries. I have interest in poultry. But it is related with many branches of science. For example, there are many places where electric supply has not reached yet. In that area to establish a farm, solar panel might be a good solution. And I have collected few panels for trial (8,10 & 20W). Now I am facing problem with battery & power calculation. Though it is for poultry but electrical engineering section can give the best suggestions I think. Would you help if I post one or two questions in electrical engineering section? By the way I have no poultry farm. I give suggestion to farmers free of cost. I follow the verse saying, "YOU HAVE BEEN SENT (TO EARTH) FOR WELFARE OF HUMAN BEING." CR4 also does this. Thank you. Anwar

I originally redirected the thread because I saw Anwar's first thread about manufacturing chicken feed and asked if this thread and it were related.

When he explained that they were, I made the suggestion about the meat grinder here because I was too lazy to go find the original thread and respond there.

Anwar did nothing wrong.

Microencapsulation is used in a wide scale in pharmaceutical encapsulation.

The material used for stomach passage and dissolution in alcalinic pH are Phtalates, fabricated by Merck.There are 5 or 6 grades available.

There is a simple approach: use gelatin for coating and harden with formaldehyde. But this may be no longer allowed. So perhaps you will find a gelatin specialist who can tell about other hardening possibilities.

RHABE

Dear RHABE, Thank you. Phtalates- Possibly I was looking for. Can you cite any web site for detail technique? Gelatin suggestion seems good for homemade product. Gelatin in cheaper & available also. Farmers would make at their home. For coating procedure- I shall try a local university. Otherwise I would have to seek support again from CR4.

I found this list of phtalates that are produced by Merck in a handbook of pharmacology I had a look into at pharmacist.

As I do not have access to this book now please search for the pharmacological products of Merck, or simply for microencapsulation and phatalate.

I wanted to do something similar with a non-approved medication so restricted to personal use only and without the support of any pharmacist. It came up that the coating is not really necessary if sufficient baking powder dissolved in water is swallowed in parallel to neutralise the stomachs acidity for some 10 minutes.

Have success

RHABE

Dear RHABE, Baking powder is Sodium tartarate & this possibly would not neutralize hydrochloric acid. Baking soda is sodium bi carbonate & can do so. But feeding baking soda with drinking water continuously would cause blood bicarbonate (HCO3-) level high & would reduce performances & egg shell quality & dirty litter. It is easy for one individual for many times a day. But for a flock even if it is be done thrice a day, it would not be practical to feed a large number of birds in this way. Up to now gelatin suggestion is still the easy way, I think. If you have any more suggestion please inform. Your (as a CR4 member) cooperation is still being sought. Thanks for your suggestion. Anwar

Phthalates have been in the news in recent years as I recall for their toxicity.
