Sažetak
The proportion of maize hybrids in the complete feed can be up to 70%, so even small differences in physicochemical properties between hybrids can affect the production characteristics of laying hens. The aim of this study was to investigate the effects of high-yielding maize hybrids on hen production traits and egg quality. Treatment diets contained 60% of grain and differed in only 15 commercial maize hybrids from six seed companies. By three in each cage, 225 Lohmann Brown hens were allocated to 15 dietary treatments in a completely randomised design (15 treatments×5 cages). The experiment lasted 12 weeks, during which egg number and weight were recorded daily, and diet intake was recorded weekly. Eggs for quality analysis were collected once a week during the last five weeks of the experiment. In terms of production characteristics, diet intake and egg production were similar among treatments, while treatments differed (P<0.05) in average egg weight (58.04-61.11 g), average daily egg mass (52.55- 60.68 g) and feed conversion ratio (2.01-2.45). For egg quality parameters, egg albumen height, Haugh units and shell thickness were similar between treatments, while treatments differed (P<0.05) for yolk colour fan (6.28-8.76) and shell strength (4.54-5.20 kg/cm2). The obtained results suggest that differences between hybrids could lead to different feed conversions and egg properties which could affect farmers' overall income.
