Sažetak
The aim of this work was to verify the production efficacy of a plant-based feeding mixture and its effect on the quality of eggs. Animal protein (i.e. meat-and-bone meal) in the feeding mixture was replaced with vegetable protein (treated lupin seed). The experiment was performed with Isa Brown hybrid females aged 22-58 weeks. The diet containing lupin seed (the variety JUNO) as a replacement of meat-and-bone meal had no negative effect on egg production and the quality of egg shell in utility layers. Moreover, the highly conclusive increase (P ≤ 0.01) was found in the following parameters: the average weight of produced eggs (60.03 g as compared to 61.66 g), the weight of egg shell (from 7.17 g to 7.78 g), and the weight of egg white (from 36.33 g to 37.31 g). The weight of egg yolk remained unaffected but its colour improved (P ≤ 0.01). Another positive effect observed with the experimental diet is that it conclusively (P ≤ 0.05) decreased the level of cholesterol in egg yolk by 15.86 g per kg.
