The influence of population density on the growth performance and stress level of Hubbard×
Hubbard chicks of equally mixed sex was studied. Six hundred and sixteen birds were
housed under. 05,. 07,. 09, or. 11 m 2 per bird (four replicates per density) from 0 to 7 wk.
There were no treatment effects on feed conversion at 6 or 7 wk. Birds housed at. 07,. 09,
and. 11 m 2 per bird had similar 7-wk BW and carcass weights, all significantly higher than
birds housed at. 05 m 2 per bird. Under. 05 m 2 per bird, a higher percentage of breast …

The influence of 2 different stocking densities (approximately 25 and 30 kg/m2 floor area) on
production performance, health and housing environment was studied on 9 Swedish broiler
farms during the summer and winter season, 1992-1993. Data on environmental and bird
conditions were collected when the birds were 3 weeks of age and the day before slaughter,
always by the same person (the National Standards Officer) together with a veterinary officer
employed by the local processing plant. With a few exceptions there were significant …
