Thanks for the nice article the highlights again the importance to chose the right types of fibre to get positive effects in poultry. One important comment on Fermentability and Solubility: That´s two different parameters which must not be mixed up. Soluble means degradable in the SMALL intestine. Fermentable means metabolized by gut microbiota in the LARGE intestine. It´s true that soluble raw ...

It is right, oat hulls will do as well in a certain extend a good job. Just need to find a source with a reasonable mycotoxin contamination. Thinking about oats is important to distinguish between the hulls and the bran. Oat hulls contain more then 99 % insoluble fiber while oat bran conains more than 50 % soluble fiber

Very good article. A recently published paper from a Polish University confirms your statement that insoluble fiber increase the growth of beneficial bacteria and inhibit the growth of harmful bacteria. Pak Vet J 2015, 35(2): 212-216. They used different Level of an insoluble crude fiber concentrate made of lignocellulose in Broilers. The researchers could see at almost all inclusion level (betwee ...

Dear Jodh Singh, one substrate (phytate) and if the same enzyme activity, and if the same thermostability = the same result. For instance, some phytases producent can be also yeast, too. No difference. If you want to select better enzyme, pls perform tests in your lab, and everything will be clear.

The more divalent cations in the diet the less soluble phytate becomes. This is especially true when drinking water pH is high and when phytate concentration is also high. In diets with high concentrations of e.g. Ca (from limestone, drinking water Ca, inorganic P sources, vegetable sources, V&M premix etc), high phytate concentration and more alkaline drinking water then the need for superdosin ...

Dear all, according to commercial trials in poultry, using SBM as a traditional protein source, optimal phytase activity for laying hens must be approx. 500 FTU/kg of feed. Dosage of phytase activity can be higher if the feed contains more appropriate substrate (phytates). If you replace SBM by SFM, phytate content becomes to be higher. The same story if you use more wheat bran or rice bran. But b ...
