Bovans Goldline hybrid layer chickens (60 experimental and 60 control birds) were reared in cages (2 layers per cage) with automatic watering, manual feeding, and at controlled light and temperature regimens. Layers received feeding mixtures and drinking water ad libitum. The feeding mixture in the experimental group was enriched with 1% clinoptilolite (ZeoFeed). The mean egg weight was 66.3+/-6.25 g in controls and 65.6+/-5.44 g in experimental birds (P less than 0.01). The consumption of feeding mixture in the experimental group was lower by 4.1 g than that in controls. Blood plasma concentrations of uric acid, cholesterol, glucose, lactose, Ca, P, ALP, and LDH ranged within reference intervals, with no significant differences between the groups. However, significant differences between both groups were found in concentrations of total plasma protein, triacylglycerol and Mg (elevated in controls). The level of AST was significantly lower in control than in experimental hens. The values of erythrocyte count, haemoglobin and mean corpuscular haemoglobin concentrations were significantly higher in experimental than in control group, whereas the leukocyte count was significantly lower.
