Rovabio™ Excel has a positive effect on corn/soybean
diets
Because Rovabio™ Excel has more than 2 or 3 global
enzyme activities, Rovabio™ is a multi-enzyme preparation
containing mainly:
- cellobio-hydrolases
- xylanases
- endo-glucanases
- beta-glucosidases
- laminarinases
- xylosidases
- arabinofuranosidases
- plus other enzymes such as proteases
Corn and soybean are also concerned by NSPs (Non-starch
polysaccharides)

How to measure the improvement of the nutritional value
of broiler feeds
|
Digestibility methodology - Growing Broilers
|
- Ad-libitum feeding :
- 0-16 days Standard feed
- 17-28 days Feed with or without enzyme
3 days adaptation
4 days excreta collection
- Experimental design :
- 2 broilers per cage
- 6 replicates per treatment
(12 broilers / treatment)
|
- Collection of excreta
Twice per day
- Analytical measurements :
- Feed intake per cage
- Individual weight gain
- Gross energy of feeds
- Gross energy of excreta
Apparent Metabolizable
Energy (N=0)
Apparent digestibility
of amino-acids
