Aaron Cowieson Thanks for the reassuring comments regarding overdosing xylanases. The concerned observations refer indeed to more than 25 years ago, thus well before xylanases were introduced on a commercial scale. As for galactose: why is it that mammals do the effort to secrete such a particular disaccharide as lactose into their milk instead of simply providing energy-supplying glucose? The ...

Dear RodelI agree, using of enzymes in sbm & wheat based diets is very vital to solving NSP problems, special when corn is expensive and we have to using wheat in large amounts.

Rodel Villaraza Dear Rodel Yes indeed the correct usage of enzymes can help in minimising the potential for digestive upsets by limiting the presence of undigested starch and protein entering the large intestine whilst at the same time NSPases have the apparent additional benefit in triggering more efficient CHO fermentation in the large intestine which can improve gut health as you suggest

in our many studies involving numerous phytase products, it seems like the term FTU is totally meaningless. supposedly 500 FTU from phytase A should be equal to 500 FTU from phytase b but seldom is.

Introduction Mycotoxins are naturally occurring secondary fungal metabolites produced both pre- and post-harvest in crops and other feed and food commodities. Fusarium, Aspergillus, and Penicillium are the most abundant mycotoxin producing mould genera contaminating feed and feed raw materials [1]. Fumonisins (FBs) are produced by Fusarium verticillioides, F. proliferatum, and other Fusarium spec ...

As Dr. Kotaiah mentioned with the latest breed, housing and feed mill technologies together with the strict biosecurity, the topic should be a closed chapter but in reality, there are countries that still rely on antibiotics like in the Philippines. That's why as a nutritionist I am pro nutrition management without antibiotics as growth promotant. With the latest and numerous studies on gut manage ...

Are multi species much more effective than single strain even if they are both spore-forming?

Alain Riggi - nice informative discussion regarding organic acids sir. Probiotic can survived even with organic acids. For me I would use combination of organic acids and probiotic to assure good growth. The organic acid would serve 3 purposes. One is what you have discussed in your above response, the other would create an environment to active digestive enzymes and propagation of good bacteria. ...

afriadi , good observation however there other organic acid that can maintain its functions and others have technology to coat these acids so that they can reach the part that needs most of the acidification.And butyric acid is not used for basic acidification. Synergistic combination of organic acids and some inorganic acid will do the trick.

Md. Abdullah Ansari Dear sir, Organic acids can indeed regulate gut's pH, but their real effect is more due to the following: Organic acids, in their un-dissociated form, penetrate the microbial cell wall. Due to the high intracellular pH, a large portion of the organic acids will dissociate and release their hydrogen ion (H+) leading to acidification of the cell content. Getting rid of these H+ ...
