Effects of Dietary Supplementation of Humic Substances on External and Internal Egg Quality of Oravka Hens

Popis výsledku v původním jazyce

The aim of this study was to appraise the effect of humic substances (HS) in different concentrations on external and internal egg quality of laying hens. In total, 20 Oravka hens were allocated to 4 treatments, each containing 5 birds. The control birds were fed a diet without additives (0.00% HS), other treatment birds were fed with diets containing HS at 0.50%, 0.75 and 1.00%. The birds in all groups had available drinking water and feed mixtures ad libitum. The experimental period lasted 16 weeks. Also, 20 egg samples from each group were randomly every 2 weeks to assess egg quality parameters. Adding HS in different concentrations significantly increased (P<0.05) egg weight, albumen index, Haugh unit and yolk index and decreased yolk percentage (P<0.05), compared with control. There were no differences (P>0.05) in egg shape index, egg volume, eggshell weight, eggshell percentage, eggshell strength, eggshell thickness, albumen weight, albumen percentage, yolk weight and yolk colour among treatments.
