The Effect of Multi-Enzyme Addition to Quail Diets on Performance, Egg Quality and Serum Parameters

Abstract

This research was carried out to evaluate the effects of different levels of multi-enzyme addition to the quail diets on performance, egg internal and external quality parameters and some serum parameters of laying quails. In the experiment, a total of 96 Japanese quails at the age of 10 weeks were randomly distributed to six treatment groups with four replicates contained with four quails in each subgroup. The experimental diets were prepared by adding 100, 500, 1000, 1500 or 2000 mg/kg multi-enzyme to the basal diet without enzyme. Body weight gain, egg production, egg weight, egg mass, feed intake and feed conversion ratio were not affected by multi-enzyme levels in the experiment. In addition, the effects of the treatments on the internal and external quality parameters of the eggs were not found to be significant, except for the eggshell thickness. Eggshell thickness increased significantly at the 1000 mg/kg multi-enzyme level. While glucose, creatinine and cholesterol were not affected from serum parameters, the AST was increased at the 100 mg/kg and albumin, globulin, total protein, calcium and phosphorus concentrations were increased with the addition of 2000 mg/kg multi-enzyme level. According to these results, it was seen that high level of multi-enzyme addition to the diet (2000 mg / kg) improved the serum parameters of quails, but this improvement in serum parameters did not reflect on the performance and egg quality of quails.
