Re: Forum: What is Egg Shell Quality and How to Preserve it?
The laying hen nutrition is not every where in the world an exact science.
We have a lot of various parameters, strains, raw matrials, production management etc…etc…etc…
For these reasons we need not to forget the basics…
Nutrition, means…Digestion, means …Absorption.
For long time, nutritionnists have forgotten an essential organ : the Pancreas.
Today, with the sodium butyrate we have the exceptional opportunity not to only think the action of stomach or intestine but also…pancreas.
Nutrition needs to be more & more functional… to help by itself.
Yes, sodium butyrate is before all a functional product.
Functional to the attraction to eat (feed intake)
Functional to the germs control (less germs in feces)
Functional to the size of villi ( over 30% length)
Functional to the pancréas secretion juice (execrine & endocrine)
Functional to the immunity (intestine is the first disponible energy)
All of these are very good, but there is a constraint
Sodium butyrate needs to be dissociated in the intestine, and not before
Sodium butyrate needs to be strongly present in the intestine & not with homeopathic dosage… the more you use …2kg, 3kg, 4kg… the more it works.
With stearine sodium butyrate protection (70/30) it is the opposite...because the more you use stearine (high point of fusion) the more you disrupt the digestibility mainly for young animal.(biblio)
Sodium butyrate seems be the true antibiotic substitute.
(Luc) I never said that Calcium butyrate was a bad product .
I only said that sodium salt have a the largest bibliography (X100 than calcium)
I only said that calcium salt is superfluous in laying hens… there still is a lot of calcium..
I only said that calcium salt is not really advised for young animal (risk of calcium soap)
At last and not at least… I* said than Calcium butyrate is without osmotic effect, because the osmotic effect is strictly "sodic" … * ( the physiology said that…not me)
And when you know the high level and need of osmotic effects for the absorption mecanism… you can may be have some doubts about the calcium salt interest ?
But calcium salt can be still active for… the others parameters..
It is true... in 1995, I perfected and sold the first sodium butyrate for animal nutrition in the world. .. and like a… "pater bonum"…I continued to perfect it
Our experience is laying hens and sodium butyrate
The problem is that we quickly stopped to promote the cracked, broked, dirty eggs advantage of sodium butyrate , because we had observed as well as a strong effects on the ESG (egg specific gravity/ Prof Harms method) on the number of eggs, on the weight of eggs, on the decrease of salmonellas in the fèces, on the level of mortality, and on the length of laying…
You can understand that the only effect on the shell quality was... into the background…
Why so nice result :
1 / because our new sodium butyrate product (patented) double buffer… with a longer dissociation in the time
2/ because the laying hens have long life, and with the diet rich in calcium there is like
a kératinisation playing as a filter on the absorption and assimilation.
3/ because our product is able through the progressive intestinal dissociation to suppress the kératinisation ( around 40 weeks) of the villi and even to relaunch the size of the villi..
4/ and because It will be possible to see on the laying courbs an increase of all the parameters…
That’s why our new sodium butyrate double buffer is able to help the laying production by a strong functional stimulation effect.
Best regards for all
