Abstract

The effect of OVOCAP preparation (based on capsaicin of Capsicum annuum) was tested on native mallards (Anas platyrrhynchоs) reproduced on a farm and settled in various areas at a defi nite age. Treatment of the experimental mallards following a prescribed scheme has caused signifi cant increase of the laying intensity – by 17,7 units above the control, as well as decrease of the forage consumption per egg.

Keywords
