The quality comparison of eggs laid by laying hens kept in battery cages and in a deep litter system.

Popis výsledku v původním jazyce

At present the laying hen rearing is being transformed into alternative housing systems, which include the deep litter system. As for the poultry nutrition, the replacement of the animal protein with the vegetable protein in poultry feed is being applied. Therefore, in the experiment, we evaluated the quality of eggs from laying hens in the cage system as compared to the deep litter system with vegetable protein substituted for animal protein in their feed. 72 ISA BROWN laying hens were placed into theexperiment. 36 laying hens were kept in the deep litter system and 36 laying hens were kept in conventional cages for laying hens. For the period of 9 months, 36 eggs from the group in the deep litter system were examined, always at intervals of five weeks (i.e. 8 x 36 eggs) and so were 36 eggs from the group in the cage system (i.e. 8 x 36 eggs). We found out that in the deep litter system the mean egg weight was higher (P<0.01), the shell weight was lower (P<0.01), the egg albumen was
