Název v původním jazyce

The effects of housing systems and age of hens on the weight and cholesterol concentration of the egg

Popis výsledku v původním jazyce

The effects of laying hens age and the housing of laying hens in conventional cages, enriched cages, the litter system and the outdoor system on egg weight and yolk and egg cholesterol concentation were studied. ISA brown laying hens were used in the experiment. The characteristics were measured at 39, 50, 59, 68 and 75 weeks of age. Fifteen eggs were always collected from each housing system. In total, 300 eggs were analyzed. There were not any significantly different results in the eggs from the hensliving in the different housing systems or from the age of laying hens on the weight of eggs. But the housing system and age of hens had a significant (P < 0.01) effect on both yolk and egg cholesterol concentration. The concentration of the yolk and eggcholesterol was the lowest (P < 0.01) in the enriched cages (12.5 mg/g yolk and 211.2 mg/egg) and the highest in the litter technology (14.1 mg/g yolk and 242.6 mg/egg). Further, there was significant (P < 0.01) influence of the interact
