Sažetak

The aim of the current work was to examine the influence of Bulgarian phytoproduct VemoHerb T (dry extract
of Tribulus terrestris –TT) on laying productivity of Japanese quails (Coturnix coturnix japonica) and their egg
morphological and sensor properties. A trial was organized with 52 female and 16 male Japanese quails from the breed
Faraon at the age of 44 days randomly divided in four groups – control and three experimental groups, 13 female and
4 male each. All birds were fed ad libitum the same compound feed for Japanese quails. The trial lasted 10 weeks. The
experimental groups received with the drink water the tested product in following daily doses: 4mg/kg body weight
(10weeks); 10mg/kg body weight (the first 5 weeks of the trial); 10mg/kg body weight (10 weeks) for Ist, IInd , IIInd
experimental groups respectively.
The addition of TT-extract improved significantly the laying productivity. It was found significant higher values of
egg weight, albumen - and yolk weight in quails from IInd and IIIrd experimental groups. There was a tendency to
increase the egg shell weight and egg shell thickness in all treated groups in comparison to the control group. The usе
of VemoHerb T did not aggravate the sensor properties of the quails’ eggs.
