Research Examines the Role Dietary Calcium Plays in Necrotic Enteritis Development and Pathogenesis

USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at Texas A&M University in College Station, Texas, in which the role dietary calcium plays in necrotic enteritis (NE) development and pathogenesis was examined. The research was made possible in part by an endowing Foundation gift from the Sanderson Farms and is part of the Association’s comprehen...

Great Subject Dr. McElroy, congratulations.
I would recommend to check the whole microbiota, sometimes we put just C.Perfringens as guilt to NE but others are also important, I believe.
Cordially,
Luis

Luis Fernando Vergamini Luna I agree with you. We do have research in progress where we will be checking the whole profile. I do believe other bacteria are impacted as well.

I find this work very interesting. I have just published a series of papers on this same work in Poultry Science. The overall outcomes are similar to what I found in my work. Can we do something further to this?

Holy Zanu hello. Yes, we have been evaluating the effect of dietary Ca on NE occurrence for the last 10 years and have shown a direct impact of Ca level, source and limestone particle size on NE. It is a very interesting interaction!

Holy Zanu we would be interested in discussions about this!

Audrey McElroy Check out for a literature review we are publishing with World's Poultry Science Journal. We are now doing the proofreading. I have proposed possible research topics in there. I can be reached at holy_zanu@yahoo.com. Thanks.

Cheapest feed ingredient, highest anti nutritional effects.first calcium satiety ,now its role in neurotic enteritis.
NRC suggest 1% ,CVB suggest 0.88%,AB vista experimented with 0.84 and 0.82% in BARC
Thailand with no negative effect on performance. We are standing on cross road looking where to go.

Hi Audrey, congratulations on the work done. I´ll be expecting your publication on WPSJ. Did you found a correlation with the pH of the litter? I read about that in french experiments and they showed the impact of the excess of calcium of the feces moving up the pH and this can change doing a reduction of Ca level on the diets.

Can you tell me the calcium and phosphorus levels of the diets?

This is very interesting Dr Audrey. I have seen 2 experiments on different calcium sources (Lithothamnion algae- Acid Buf compared to Limestone) at reducing levels of calcium in the diet. The experiments looked at the digestive tract health and pH. The Lithothamnion algae calcium source resulted in lower digestive tract pH and had a lower Acid binding capacity. Will you be looking into different calcium sources linking it into NE development in your future research?
