Video camera technique for observing essential behaviour patterns in caged laying hens at different cage densities

, : Video camera technique for observing essential behaviour patterns in caged laying hens at different cage densities. Beobachtungen einiger als essentiell anzusehender Verhaltensweisen von Legehennen in Kafigen mit unterschiedlicher Besatzdichte unter Verwendung der Videotechnik: 104

Cramped conditions (a floor area of 350 cmsuperscript 2, compared with 650 cmsuperscript 2 per bird) inhibited feeding, drinking and certain habits like wing-stretching, preening and body shaking.

In each of five sequential trials, laying hens (56-72 wk of age) were challenged with Salmonella and Campylobacter, and 1 wk postinoculation, the challenged hens (n = 3) were commingled with nonchallenged hens (n = 12) in conventional wire cages,...

Birds housed in the top tier showed (a) longer durations of tonic immobility, (b) grea...
