Název v původním jazyce

Comparison between laying hen performance in the cage system and the deep litter system on a diet free from animal protein.

Popis výsledku v původním jazyce

Battery cage systems for housing laying hens are being replaced by alternative systems including the deep litter system. At the same time, the substitution of vegetable matter for meat and bone meal in poultry feed mixtures is sought in the nutrition oflaying hens. In the experiment, we compared the performance of laying hens of the ISA BROWN hybrid in both the cage system and the deep litter system, on a diet where the meat and bone meal content was replaced by vegetable feeds (based on lupin). In thefirst group, 36 laying hens were kept in the deep litter system; in the second group, 36 laying hens were kept in cages. Over the period of nine months, the number of eggs laid, their weight, shell quality, the clinical state of the laying hens and their incidence of mortality were monitored daily. We found that in the cage system a higher number of eggs was obtained, a lower mean egg weight (p < 0.01), a higher number of eggs per hen per day (p < 0.01), a higher egg mass weight per hen
