This detailed report of a Natuzyme (multienzyme) product in commercial Broilers.
The present study has been carried out to avaluate the action of a product containing multiple enzymes for improved feed utilization in poultry.
Material and methods
Studies were conducted at two different commercial broiler farms consisting of 4000 and 12000 birds respectively. Day old chicks at both the farms were randomly divided into two different Groups 1 & 2 of 2000 (Cobb) and 6000(Hub Chix), each and reared in separate compartments under standard managemental conditions in a well maintained broiler house. Own prepared standard broiler starter and finisher feed were used at both the farms. (Starter protein 22%, ME 2800K. Cal/Kg and finisher protein 20%. ME 2950K. Cal/Kg), Corn / Soy diets.
Group 1 birds at both the farm received Natuzyme (multienzyme) product @ 500 gm/per tonne of feed from day 1 to unfill disposal (47 days) and Group 2 birds were kept as untreated control. No other performance promoter is administered either through feed or water throughout the period.
The data on feed consumption, body weights, feed conversion ratio, mortality, livability and litter conditions were recorded.
Results and Discussions
In both the studies there is improvement in average body weight gain in the treated flocks.
The feed consumption is also less in the treated groups, thereby F.C.R. has improved. The mortality recorded is also less in the treated flocks, thereby, there is improvement in the livability. The litter condition is also dry in the treated groups. (Table 1).

Conclusion
Enzymes have been documented to overcome poor performance of poultry. In the present study the birds treated with enzyme preparation have consumed less feed and gained more body weights, this shows that all the enzymes present in the product has helped in better digestion of nutrients available in the feed.
The overall performance of the treated groups are better when compared to the untreated groups. Further in the present study there is significant reduction in the viscosity of faeces and sticky droppings, thereby the dry matter content of the litter has improved due to better absorbion of nutrients from the intestinal tract. |
