Abstract
The objective of this study was to assess an impact of organic selenium (Se) feed additive and enzyme additive “Vilzim” on some morphological indices of eggs of laying quails. 240 female quails were divided into 4 groups, 60 birds each. Group 1 was the control group. Feed for the trial group 2 was supplemented with the enzyme additive “Vilzim” (20 mg/kg). Feed for the trial group 3 was supplemented with 150 mg/kg of feed additive and for the group 4 with both 150 mg/kg of feed additive and with 20 mg/kg of “Vilzim”. Results indicate that these additives had an influence on morphological indices of eggs of the 19 weeks old quails. In group 2 egg weight had increased by 1.01% (p<0.05), in group 3 by 0.7% and in group 4 by 3.7% (p<0.05) in comparison with control. In trial groups the weight of egg shell had increased in comparison with the control. Egg shell thickness was the highest in the trial group 2 and was 4.7% (p<0.05) higher than in the control group. Haugh units of eggs of the trial group 4 were 2.72% (p<0.05) higher than in the control group. Selenium content in the egg yolk in trial groups 3 and 4 was increased in comparison with the control group. Total number of eggs produced by the quails of the trial groups 2 and 4 was bigger than the egg number of the control group. Intensity of lay in the trial group 4 was 9.18% higher than in the control group.
