Relationships between bilateral asymmetry and tonic immobility reaction or heterophil to lymphocyte ratio in five breeds of chickens.
Bilateral asymmetry of several morphological traits, tonic immobility reaction, and leucocyte ratio were studied in hens and cocks from four Spanish breeds of chickens (Castellana, Buff Prat, Red Villafranquina, and Barred Red Vasca) and an F2 cross between Castellana and Buff Prat (C x BP - F2). Any two or all three types of bilateral asymmetry (fluctuating asymmetry, directional asymmetry, an...
متن کاملEffect of lighting stress on fluctuating asymmetry, heterophil-to-lymphocyte ratio, and tonic immobility duration in eleven breeds of chickens.
The purpose of the present study was to analyze the effect of a lighting stress on the fluctuating asymmetry (FA), the heterophil-to-lymphocyte ratio, and the tonic immobility duration of chickens. The experiment (440 birds) measured the FA of several traits (outer, middle, inner, and hind toe lengths and leg, wing, second primary feather, and spur lengths), the heterophil-to-lymphocyte ratio, ...
متن کاملTonic immobility reaction and heterophil to lymphocyte ratio in hens from three Spanish breeds laying pink eggshells.
Tonic immobility reaction and heterophil:lymphocyte ratio were studied in hens laying pink eggs from three brown egg Spanish breeds (Barred Red Vasca, Red Vasca, Red Villafranquina). There was no significant difference among breeds in terms of tonic immobility duration or heterophil:lymphocyte ratio. Tonic immobility duration was significantly shorter in the pink (220 + or - 23 s) than in the n...
متن کاملAssociations among fluctuating asymmetry, duration of tonic immobility, heterophil-to-lymphocyte ratio, and one-legged standing, crooked toes, or footpad dermatitis in chickens.
The purpose of this study was to analyze the associations among fluctuating asymmetry, duration of tonic immobility, heterophil-to-lymphocyte ratio, and one-legged standing, crooked toes, or footpad dermatitis in chickens. In experiment 1, cocks (n = 96; 36 wk old) from 11 Spanish breeds and a White Leghorn population that showed one-legged or normal standing were used. There were no significan...
متن کاملCholinergic blockade and tonic immobility in chickens
To investigate the effects of cholinergic blockade on duration of tonic immobility (TI) and habituation to handling and the TI testing procedure, two groups of cockerel chicks were tested following injection with scopolamine or saline. One week later half of each group was given a second test for TI following injection with saline or scopolamine. Results indicated that scopolamine significantly...
