Adisseo's Rovabio demonstrates efficiency in various broiler strains
In two different trials carried out at the University of Sao Paulo, in Brazil, Adisseo demonstrated that RovabioÂ®, the versatile NSP enzyme, improves performance of the two important broiler strains on the market - Ross 308 and Cobb 500.
However, the impact of RovabioÂ® was rather different between both strains (depending on the production phase).
Broiler strains have different nutritional requirements depending on their specific growth performance. This is because their genetic evolution might be different. Adisseo looked into the effectiveness of carbohydrase enzymes in the different genotypes.
In Cobb, RovabioÂ® had a better improvement on feed conversion between zero and 21 days (Graph 1), due to a larger decrease of feed intake when fed with RovabioÂ®. In Ross, RovabioÂ® showed a better improvement of feed conversion between 22 and 42 days (Graph 2), likely due to enhanced digestibility as changes in feed intake are similar in both strains.
Graph 1: Improvement of performance with RovabioÂ® for Cobb 500 and Ross 308 strains between 0-21 days.
Graph 2: Improvement of performance with RovabioÂ® for Cobb 500 and Ross 308 strains between 21-42 days.
Thus, RovabioÂ® always improves broiler performance on the zero to 42nd day period in both trials, irrespective of the strain (Ross 308 or Cobb 500), further supporting its versatile enzyme profile.
