Can we substitute avilamycin by a non medicated solution in broiler production ?
- intestinal integrity at 28 and 35 days of age (HTSI methodology-Elanco).
Very good informative article on clay. Yes indeed this substance can be used in poultry feed
Several research articles have been published.
Here is an article carried in our university :

In this trial it was possible to change B-SAFE inclusion level and we know that it is more benefic for animals' gut flora to vary B-SAFE concentration. But some of our customers prefer using B-SAFE at a fixed level during all the breeding period and it works too. It depends on your facilities and your objectives.
It is very difficult to be use B-Safe inclusion level regarding age of birds.
To Sergio Velez: a third group would have been probably better, you're right; but it was a field study with a customer and only 2 treatments were possible. We have divided the buildings into 2 groups and fed animals as usual=ad lib. But we have done other trials in research centers with more treatments that show the same trend as this trial (in comparison with antibiotics growth promoters).
B-SAFE is a clay activated by copper. Copper has an antimicrobial activity which is potentialized by the localisation of the copper at the surface of the clay. A very low level of copper is enough to have antimicrobial activity of B-SAFE because of its patented process. We have now backep up this product for 10 years and we have a lot of trials, in-vitro and in-vivo which show B-SAFE efficacy on the modulation of gut flora, height of villosities and thus on zootechnical performances.
B-SAFE can be added to organic acids or replace them, each breeding situation must be evaluated.
To S.M.A. Halim: B-SAFE has shown in-vitro antimicrobial activity against Clostridium perfringens and Clostridium sporogenes. In-vivo, B-SAFE is very often used to fight against wet litter due to digestive disorders and gut flora imbalance.
To Dr Dhar: in this mexican trial, no evaluation of the gut flora was done but some animals were evaluated by Elanco method to make a scoring of intestinal integrity : lesions of the different parts of the gut,...
This trial was published at Alternatives to Antibiotics symposium, last september in Paris.
Thank you for your comments!

Dear : I think the global tend is to find alternative way to antibiotics which used as a feed additives like avilamycin , vancomycin , lincomycin and I read many of articles about the same subject using organic acid as a growth promoting , at the same time we use organic acids in drinking water to control the disorder of the gut we found very good resluts.
Thx 4 ur efforts
Dr yahia sumiaat
I would have wanted to see a third treatment: a negative control without the clay and the antibiotic. Dont you think?
Also, although I am sure much more controversial ( and i understand there are arguments against): I would have wanted animales to be fed to an equal intake ( although consdering the sample size and the traditional feeding practices (in most countries, not all) this seems difficult).
