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 (between 0,25 and 1 %) a significant increase in lactic acid bacteria and bifidobacteria and at the same time a signifgicant reduction in e coli and clostridia in Ileum and caeca.
Thank-you. The article "Pak Vet J 2015, 35(2): 212-216" mention "There was no significant effect of lignocellulose inclusion into the diet on broiler performance indices" and as you know in broiler, technical and economical performances are the driving force.
So two comments:
- Results is the field or in the "real world" can be different especially when we talk about gut balance and mortality.
- There are many sources of insoluble fiber. Some work show positive results using oat hulls for instance. A cheap raw material in some place.
Thanks for the great comments from all. Indeed, during these hard times with expensive SBM and corn prices, turning to higher fiber cheaper ingredients will truly help reduce feed costs
As recommended level of crude fiber in broilers should not exceed 5% in the final feed. But can we increase more than 5%, especially during grower and finisher phase?
Fibre, as explained, is a forgotten nutrient but very important in a formulation for some reasons. In poultry production if it's too high the birds may not perform as expected and its complete absence is still not very good. Therefore, there is need to balance the fibre and be sure it does not exceed the limit of broilers, cockreal and layers.
Hi everybody, i think that we forget to speak about the type of the fiber. Is it soluble fibre or non soluble fiber !!! very important ...
