Effect of a multi-enzymaticmix in a sorghum-soybeanmeal-based ration on henperformance

摘要

The use of individual enzymes in the diet ofhens has shown an improvement in egg production,and mixtures are now being included toincrease feed utilisation and impact on performancein hens. The objective of our studywas to evaluate the use of an enzyme blend in asorghum-soymeal-based ration (protein 17.5%and ME 2900 kcal/kg) on performance. Hens oftwo lines: Hy-line (n=732) and Bovans white(n=365), aged eighteen weeks, were used toevaluated three treatments (control, Ronozymeblend or Cybenza). The birds were lodged incages with a density of 485 cm2 per hen (fourhens per cage). There were no differences(P>0.05) among enzymatic treatments or theirinteractions with the hen line on egg yield, eggmass, feed-to-egg ratio, or egg quality. However,the efficiency was higher with Hy-line (P<0.05)and enzymes (P<0.05) but was not affected bythe interaction (P>0.05). Based on our results,we concluded that the use of a multi-enzymemixture in a sorghum-soymeal-based hen feedhas a minor effect on performance, regardlessof hen genetics.
