Effect of keeping crossbred laying hens in cages or on the floor during rearing and laying on growth, egg yield, utilisation of feed and losses. (Results of 3 trials.)
Archiv fur Geflugelkunde 35(2): 88-92
In 3 trials 2300, 2500 and 2300 female chickens were reared from 1 day old throughout the laying period in cages, or reared from 1 day to 20 weeks on the floor after which some were transferred to cages and the rest remained on deep litter. In one case the litter-reared birds were put into cages at 9 weeks. Up to age 20 weeks the caged pullets were lighter in 2 trials and heavier in the trial with concentrated feed. Feed conversion was 2 to 5% better and losses were fewer in caged pullets.
