“…The differences in TI durations between breeds (Gallup et al 1972;Jones and Faure 1981;Jones and Mills 1983) and strains within breed (Gallup 1974b;Benoff and Siegel 1976;Craig et al 1983) suggest the importance of a genetic factor in fear-related behaviour in poultry. In the present study, it was apparent that RJF were more fearful than CB as assessed by a test of TI.…”

Zulkifli, I., Dass, R. T. and Che Norma, M. T. 1999. Acute heat-stress effects on physiology and fear-related behaviour in red jungle fowl and domestic fowl. Can. J. Anim. Sci. 79: [165][166][167][168][169][170]. Two experiments were conducted to compare heat tolerance of red jungle fowl (RJF) and commercial broilers (CB) at (i) a common age and (ii) a common body weight. In exp. 1, RJF and CB of a common age (8 wk) were exposed to 36 ± 1°C for 6 h. RJF had smaller increases in heterophil to lymphocyte ratios and body temperature and higher serum cholesterol concentrations than CB in response to the heat treatment, while tonic immobility (TI) measurements were not affected by heat stress. In exp. 2, RJF and CB of a common body weight (1000 ± 150 g) were subjected to similar procedures as in exp. 1 (except TI durations). Both breeds responded similarly to the heat treatment. In both experiments, RJF had higher serum glucose level than CB, and the trait was not affected by heat exposure. Deux expériences ont été réalisées pour comparer la tolérance à la chaleur des galliformes rouges d'Asie (GRA) et des poulets de chair de production commerciale (PC) à un même âge et à un même poids corporel. Dans l'expérience 1, les GRA et les PC du même âge (8 semaines) étaient exposés à une température de 36 ± 1°C pendant 6 h. Les GRA manifestaient des accroissements moins importants du rapport hétérophiles-lymphocytes et de la température corporelle ainsi qu'une plus forte concentration sérique de cholestérol que les PC en réponse au traitement thermique. Par ailleurs, les valeurs d'immobilité tonique (IT) n'étaient pas touchées par le stress thermique. Dans l'expérience 2, les GRA et les PC de poids corporel comparable (1 000 ± 150 g) étaient exposés aux mêmes conditions que dans l'expérience 1, excepté pour la durée de IT. Les deux types de volaille réagissaient de la même façon au traitement thermique. Dans les 2 traitements les GRA avaient un niveau sérique de glucose plus élevé que les poulets domestiques et ce caractère se maintenait en présence de stress thermique.

“…The tonic immobility (TI) test was applied as Jones & Faure (1980) reported. Animals whose TI time was longer were evaluated as more passive, referring to fear while those with shorter TI period were evaluated as being more active and fearless.…”

This study aims to examine the effects of environmental enrichment (EE) practices on some physiological and behavioral parameters of broiler chicks. A total of 280 one-day old Ross 308 mixed-sex broiler chicks with an average initial body weight of 44.5±0.37 g were used in a 42-d trial. Broiler chicks were randomly allocated to 20 pens composed of 14 birds in 1x1.4m sized floor area. Each of the EE treatment consisted of 5 replicate pens (70 chickens per treatment). The treatments were 1) control; 2) perch for EE; 3) ball for EE; 4) mirror for EE; and 5) dust for EE. Final body weights, tonic immobility test results, and rectal temperatures were recorded. Spleen, liver, and bursa fabricius weights were measured. The blood biochemistry of birds was analyzed at the end of the experiment. Besides, gait score test was applied on the 42 nd day of experiment. Body weight gain, lymphoid organ weights and rectal temperature values of broilers were not affected by EE treatments on the 21 st and 42 nd days of the study. At the end of the study, WBC values, tonic immobility values and gait scores of the control groups were found higher than those of the EE groups. HCT and PLT values of the ball groups were found lower than the other groups, concluding that EE improved the welfare of birds.

“…This innate behavioural response induces physical immobility similar to a catatonic-like state, resulting in decreased predator's attention. The number of attempts to induce TI and the duration of TI are both indicators of the level of human fear (Jones and Faure, 1981). The higher the number of attempts and the longer the TI duration, the stronger the fear (Gallup, 1977).…”

Mule duck, a cross between a Muscovy drake and a Pekin female, is reported by the farmers to frequently express fear behaviours, such as man avoidance. The genetic basis of fear responses in mule ducks was therefore investigated in this study. According to a previous experiment, the dominant effect of Pekin genotype was hypothesised; however, due to the absence of birds from the reciprocal cross, a superiority of the Pekin in additive effect could not be distinguished from a direct maternal additive effect. In order to clarify this, ducks from the mule genotype, the two parental genotypes (Pekin and Muscovy) and the reciprocal intercross (hinny) underwent a set of physiological and individual behavioural tests of fear. Both parental genotypes were highly fearful but exhibited responses of different patterns: Pekin ducks manifested a higher locomotor activity, whereas the Muscovy ducks showed a higher avoidance to man. Hybrids expressed higher panic responses and specific fear of man than the two parent breeds. Both hybrids expressed similar patterns and the maternal effects were not significant. Significant heterosis effects were found for most of the behavioural responses, in agreement with the fact that higher fear responses were expressed by the hybrids compared to the parental genotypes. A significant heterosis effect was also found for basal adrenal activity; hybrids having higher basal level than parental genotypes. Maximum capacity of adrenal response appeared to be determined by direct additive effects with a superiority of the Pekin genotype.
