Effects of a Water Applied Biopromotor and Feed Applied MOS on the Prevalence of Colibacillosis and Egg Production in Commercial Heavy Breeders

Summary

Abstract:

Commercial poultry production farms are under increasing pressure to reduce the use of antibiotics while maintaining health standards and pathogen control. Currently, there is an increased need for the development of effective products that serve as alternatives to antibiotics. We have developed a water applied biopromoter through careful selection of different types of prebiotics strategies (inactivated fermented Bacillus subtilis fragments and yeast cell wall extracts) that improves mucosal integrity and controls gram negative pathogens, while increasing productivity parameters and health status of the birds.

A commercial poultry farm (Ross 508 heavy breeders), Cuenavaca, Mexico, with a historical problem of increased mortality, increased diarrhea and reduced egg production attributed to Colibacillosis beginning at week 28 was divided into two treatment groups (n=2 houses). House 1 (n=20000 heavy breeders) served as the untreated control and was fed a commercial basal diet without AGP and House 2 (n=20000 heavy breeders) was treated with 2 doses of the biopromoter (0.2ml/bird) in the drinking water at week 24 and 18 days later and MOS incorporated into the standard commercial basal diet (2kg/ton) free of AGP during weeks 25-34.

Results show significantly increased mortality in the untreated house beginning at 28 weeks and continuing until 34 weeks, comparable with historical farm data, while birds in the treated house presented normal mortality consistent with stress associated during the peak of production.  Microbiological analysis confirmed that the increased mortality in the untreated house was consistent with Colibacillosis. Through peak of production the treated house achieved 84.48% production while the control house achieved a maximum production of 67.03%.

Analysis further showed egg production in the treated house was significantly higher (n=899,230) when compared to the untreated control house (n= 497,425).  These data indicate that treatment with two doses of the biopromoter and temporary incorporation of MOS into the commercial basal diet can moderate the effects of E. coli in heavy breeders. Furthermore, this strategic approach of combining prebiotics provides an excellent alternative intervention strategy to chemotherapeutic agents.

Key Words: Biopromotor, Colibacillosis, Breeders, MOS.

Great thanks to Carlos De Oliveira, Justino Hernandez and Sherry Layton for this interesting presentation. I observed from the presentation, that the farm in question had a historical challenge of colibacillosis, diarrhea and reduced egg production. But with the introduction of a bio-promoter and yeast cell wall [ MOS] in a treated pen, there was a general improvement in health status of the birds and egg production, with reduced mortalities. Now my suggestion is this, while I was a poultry manager years back here in Badagry, Nigeria, we observed the same challenge, we checked the feed ingredients, which were not constant. We checked the water, which was a constant and observed bacterial contamination from water lines and water holding tanks. Flushing and cleaning with appropriate medicament were done with great success. I suggest and advise that poultry caretakers should constantly check water source in order to avert constant enteric challenges.

Hi Interesting work. What interested me most is the process of making the inactivated Bacillus subtilis fragments. What type of microorganisms that were involved in the fermentation and do you have any idea of sizes of cell wall fragments.

Hi, I think this is a good report and it could be a great way to control the E coli infections. I would like to know which company produce this product, and is it in the market or not?

This is the new trend in poultry nutrition and its a good data to overcome the the increasing mortality and to enhance the egg production, but you added 2 levels in water while, i find only one level (0.2ml/ bird) in 2 ages (24 w and 18 days later) and its need clarification and which level led to these results. Many Thanks
