摘要
The efficiency of enzyme additives containing beta-glucanase and xylanase to layer rations on a barley-rye and wheat-rye basis was tested in a 12-week performance trial. All treatments were rested either using ad libitum or restricted feeding. The tested enzyme preparations revealed no significant influence on the performance parameters, neither in ad libitum feeding nor in restrictive variants. The quantity of dirty eggs was slightly decreased due to the influence of enzyme supplementation on the excreta consistency (lower viscosity). This effect was even stronger in the groups on restrictive feeding.
