The effects of movable roosts, relationship of cage mates (siblings versus nonsiblings), and genetic stock on measures of behavior, production, and physical condition were investigated. Sibling and nonsibling pairs of hens derived from two male parental stocks (designated MPS1 and MPS2) were randomly assigned to two cage batteries (384 hens total). The batteries were identical except that the cages of one had individual wood roosts, which were automatically raised at night and lowered the next morning. The laying phase comprised 13 28-day periods. On the first 4 days of Periods 1, 3, 5, 7, 9, and 11, video recordings were made of 8 cages per day. Video-recorded data for Period 5 were discarded, however, because equipment failure caused an unplanned photoperiod ratio. Direct visual observations were carried out in Period 13. Egg production and feed consumption were recorded in each period. Feather scores were determined in Periods 3, 6, 9, and 12, and in Periods 6 and 13, hens were weighed and the number of lesions to the feet counted. Overall, roosts appeared to improve well-being. Resting occurred more in cages with roosts, feathering was better initially, body weights were slightly higher, and foot lesions were were fewer. Egg production was not affected except that egg cracks were more frequent in roosts cages. Relationship of cage mates had relatively little influence. However, in conventional cages, nonsiblings manifested more bobbing behavior, and in MPS1, nonsiblings had higher feed consumed per dozen eggs. Hens of MPS1 performed more head flicking, drinking, physical displacement, aggression, and cage wall climbing than MPS2 hens. They also had higher egg production, weaker egg shells, poorer feathering, and more lesions to the feet. The genetic stock differences suggest that hens of MPS1 experienced poorer well-being. None of the treatments significantly affected mortality.

“…Although the open field test was originally developed for comparative psychology in rodents, nowadays it can be used to determine welfare in farm animals, such as pigs (Mormede at al., 1994), chickens (Webster & Hurnik, 1989), quails (Jones at al., 1991), sheep (Moberg et al ., 1980) and cattle (Mullens et al ., 2006). …”

In various areas of the bio-medical, pharmacological and psychological research a multitude of behavioural tests have been used to investigate the effects of environmental, genetic and epi-genetic factors as well as pharmacological substances or diseased states on behaviour and thus on the physiological and psycho-social status of experimental subjects. This article is reviewing the most frequently used behavioural tests in animal research (open field, elevated plus maze, zero maze, and black and white box). It provides a summary of common characteristics as well as differences in the methods used in various studies to determine motor activity, anxiety and emotionality. Additionally to methodological aspects, strain, sex and stress-related differences as well as the involvement of nitric oxide in modulation of motor activity and anxiety of rodents were briefly reviewed.

“…Common fear-avoidance is associated with escaping, jumping and flight behaviours in an open field test (Melik et al 2006;O'Brien and Sutherland 2007). Estimates of heritability (h 2 ) in open field behaviours have been observed in several studies and found to range from 0.08 to 0.49 for overall locomotion and from 0.06 to 0.10 for defecation (Boyer et al 1970;Faure 1981;Webster and Hurnik 1989). Ambulation in the open field is also heritable (Forkman et al 2007).…”

This study was carried out to investigate the behavioural responses of white and bronze turkeys to tonic immobility (TI), gait score (GS) and open field (OF) tests in a free-range system. 144 female turkeys (72 white and 72 bronze) were studied for 23 weeks. They were 32 weeks old. The stocking density was 2 birds/m 2 indoors and 0.66 birds/m 2 outdoors. Both bird genotypes were fed on a diet containing 16% crude protein and 11.7 ME MJ/kg. The birds were weighed in the 32nd, 35th, 48th and 55th week. The turkeys' behaviour was determined by TI, GS and OF tests. Behavioural parameters were established for each applied test. Although the mortality rates of white and bronze turkeys during the study were 6% and 3%, respectively, the white turkeys showed better results in the TI and OF tests suggesting that are more native breed than bronze ones. The results indicate that bronze turkeys are more suited for use in free-range systems than white turkeys with respect to GS and the consequent mortality rates in latter ones.
