This study assessed the efficacy of pre-operative injected lignocaine and peri-operative topical vapocoolant spray, administered as most practical for incorporation into routine calf castration procedures. Calves were randomly allocated to: (1) sham castration (SHAM); (2) surgical castration (CAST); (3) surgical castration with lignocaine (LIG); and (4) surgical castration with vapocoolant spray (VAPO). Calf behavioural responses were scored at different stages of the sham castration or castration procedure. Maximum ocular temperatures were measured at three time-points relative to restraint and treatment. There were significant effects of treatment (p < 0.001) and stage of procedure (p < 0.001) on calf behavioural response. SHAM calves were more likely to display less severe responses compared to all other calves and LIG calves were more likely to display less severe responses compared to VAPO calves. Calves were more likely to display more severe responses to extrusion of the first spermatic cord compared to all other stages of castration, and to extrusion of the second spermatic cord compared to severing of the second spermatic cord. There was a significant effect of time (p < 0.001) on ocular temperature, with ocular temperature being greater following sham castration or castration. In this study, there was no evidence of pain reduction during castration of calves by either lignocaine or vapocoolant spray.

The objective of the present experiment was to compare the behavioural response of calves reared by cows of different milk yields to the prevention of suckling with the aid of nose-flaps that allowed the maintenance of social contact with the dam. Twenty Hereford or Hereford × Angus crossbred primiparous cows from a single herd remained with their calves suckling until the beginning of the experiment, in late summer–early autumn. Milk production was determined monthly during the lactation period and the pairs were selected according to the cows’ milk production, for higher or lower milk yield (HMY and LMY, respectively). On Day 0, suckling was prevented by placing a nose-flap anti-suckling device on each calf for 11 days. Calf behaviour was recorded from Day –3 to Day 5, using instantaneous sampling of individual animals in each group, and the calves were weighed monthly since birth, and on Days –8 and 11. Bodyweight profiles for HMY and LMY calves were similar until Day –8; from then on, up to Day 11, HMY calves lost weigh, whereas LMY calves gained weight. Suckling frequency before nose-flaps were fitted was similar for HMY and LMY calves. There was no relationship between the cow’s milk yield and the changes observed in behaviour. Apart from playing, all behaviours were affected by prevention of suckling. The distance between the calves and the dam, and the frequency of grazing and rumination, decreased after nose-flaps were placed, whereas vocalisations, suckling attempts, walking and standing increased. In conclusion, the behavioural responses to prevention of suckling did not differ between the 6-month-old calves reared by cows with high yields and those with low milk yields. The behavioural response of calves that were prevented from suckling but were kept with the dams indicates that the cessation of suckling contributes to the weaning distress of 6-month-old beef calves.

AbstractThe Anthropocene marks great changes to environments and the animals that inhabit them. Changes, such as disturbance, can affect the manner in which animals interact with their environments, such as moving and selecting habitats. To test how animals might respond to changing disturbance regimes, we employ an experimental approach to movement ecology. We used integrated step selection analysis (iSSA) to test the behavioural responses of individually-marked grove snails (Cepaea nemoralis) exposed to a gradient of physical disturbance in their habitat. We used a before-after control-impact (BACI) experimental design within semi-controlled mesocosms to manipulate edge and disturbance variables by altering the area of the mesocosm covered by bricks. We showed that grove snails perceive edges of enclosures and edges of bricks as risks, and responded to such risks by altering their movement. Grove snails displayed a bimodal response to risk by taking shelter in place or moving faster to be farther from the disturbance. Furthermore, individuals tended to modulate their behavioural response to the degree of risk. Our study highlights the usefulness of experimental mesocosms in movement ecology and in determining the effects of habitat alteration and human-imposed risk on movement behaviour.

SUMMARYIn order to test the hypothesis that snakes can not only perceive airborne sounds, but also respond to them, an acoustic isolation chamber was designed and constructed to perform best within the 150-450 Hz range in which snakes perceive sound. Suspended within this acoustic chamber was a steel mesh basket designed to minimize the potential for groundborne vibrations. A synthesized tone was created out of 20 different 150 ms sounds, each separated by a 50 ms period of silence; the acoustic energy of each of the 20 sounds was concentrated between 200-400 Hz, and each sound included frequency modulation. The trial stimuli were presented to western diamondback rattlesnakes Crotalus atrox at a level 5-10 dB above their perception threshold. Four significant behavioural responses were observed upon stimulus presentation: cessation of body movements, reduction or cessation of tongue flicking, rapid jerks of the head and rattling. At least one significant behavioural response was observed in 92% of the behavioural trials. This study provides the first experimental evidence that snakes can respond behaviourally to airborne sounds.

The giant rotifer Asplanchna sieboldi swims by the propulsive effect of thousands of cilia arrayed in clusters around the apical field, which has several mechanosensory structures (sensilla) located at defined positions. Males and females differ in both their patterns of behaviour and their sensory receptor equipment. Unstimulated males swim straight with occasional spontaneous changes in direction until they hit an obstacle with their apical field. Depending on the direction and the strength of the mechanical interference, the animals show different behavioural responses. To analyse the effect of excitation of the apical mechanosensitive sensilla on these responses, males were held on microcapillaries, and the sensitivity of individual sensilla was assayed using micromanipulator-mediated mechanical stimulation. Stimulation of each of the four different types of sensillum triggered a specific and well-defined initial behavioural response. Individual animals behaved identically with respect to the receptor specificity of the responses. The behaviour of free-swimming males upon contact with obstacles or females is discussed on the basis of these results.

PURPOSE: To investigate the effect of alanyl-glutamine dipeptide (L-Ala-Gln) pre-treatment on ischemia-reperfusion (I/R) injury after unilateral testicular torsion-detorsion in a comparative controlled experiment. METHODS: Forty-eight rats (150-200 g) randomly distributed into 4 groups (n=12), and distributed in 2 subgroups (n=6) each, were treated with saline 2.0 ml (G-1, G-3) or L-Ala-Gln 20%, 0.75g/kg dissolved in saline (total volume 2.0 ml) administered in the left saphenous vein 30 minutes before ischemia. Anesthetized rats were subjected to I/R induced by torsion (720°) of the right spermatic cord lasting 1h (G-1, G-2) or 3 hours (G-3, G4). Anesthesia was again applied at the end of ischemia time (T-0) for testis detorsion and 6 hours later (T-6) for orchiectomy. All operations were performed on the right testes through transverse scrotal incisions. Right orchiectomy was carried out at the end of ischemia (T-0), and 6 hours later (T-6) to evaluate the concentrations of malondialdehyde (MDA) and reduced glutathione (GSH) in the testis. RESULTS: Pretreatment with L-Ala-Gln reduced MDA contents in rat testis at the end of ischemia lasting 3 hours. There was significant increase of GSH levels in T-6 time-point after 1 hour of ischemia. GSH levels also increased in T-0 and T-6 time-points in rats subjected to ischemia for 3 hours. CONCLUSION: L-Ala-Gln administered before torsion/detorsion of the spermatic cord decreases lipid peroxidation during ischemia and protects the testis from oxidative stress by upregulating GSH levels during reperfusion.

The purpose of this experiment was to evaluate the behavioural response of Boer goats and Tswana goats to successive handling. Boer goats and Tswana goats were subjected to aging and tail restrain during handling. Behavioural response was recorded through the vocalisation score (VS), crush score (CS), flight speed (FS), and flight time (FT) scores twice a week for eight weeks. A total of thirty six Boer goats and Tswana goats were used in this experiment. The results indicated that the Tswana goats were the most temperament (p < 0.05) and Boer goats were the calmest. Behavioural scores significantly increased throughout the experiment.

Two-step weaning with nose flaps is used to minimise the stress of weaning in beef calves. Farmers leave the nose flaps for 7–30 days, basing the period on practical considerations. Thus, the objective of this study was to compare the behavioural response of 6-month-old beef calves fitted with nose flaps during 7 or 21 days before permanent separation from the dam, or abruptly weaned. Angus × Hereford cow-calf pairs were assigned to: (1) calves fitted with nose flaps on Day –7 and permanently separated from their mothers on Day 0 (NF7), (2) calves fitted with nose flaps on Day –21 and permanently separated from their mothers on Day 0 (NF21), and (3) calves abruptly weaned on Day 0 (CON). Behaviours (standing, lying, walking pacing, grazing, ruminating and vocalisations) were recorded during 3 days before and 5 days after permanent separation from the dam. On Days 1–3, standing and grazing behaviours decreased, whereas walking, pacing and vocalising increased in CON calves but not in NF7 or NF21 calves. Control calves differed from NF7 and NF21 calves for all these behaviours. The two nose flap treatments differed only on Day 1, when the changes in the frequency of walking, lying and standing were smaller in NF7 than NF21 calves. In conclusion, nose flaps can be used for periods from 7 to 21 days before permanent separation from the dam, diminishing the behavioural indicators of distress provoked by weaning.

Abstract Fishes are often caught as bycatch on longlines and subsequently discarded. The behavioural response of fishes to longline capture is poorly understood, although it may be linked to the magnitude of the physiological stress response, and, ultimately, contribute to stress-induced mortality. We used accelerometers, video cameras, and hook timers to analyse the behavioural response of 13 subtropical teleost and elasmobranch species to experimental longline capture in The Bahamas. We found that, across all species and species groups, fight intensity during a capture event was best described by a negative linear and positive quadratic response. Nurse sharks and tiger sharks had lower fight intensity values and exhibited less steepness in their quadratic response during the first 10 min of capture than other species, particularly blacktip and Caribbean reef sharks. Nurse sharks also exhibited the most consistent fight intensity during the entire capture event compared to other shark species, particularly the blacknose shark. Generally, obligate ram ventilators and mixed ventilators exhibited higher steepness in fight intensity trajectories than buccal/spiracular pumpers, which had more consistent, lower fight intensity values. Behavioural responses to longline capture are species specific but may be linked to distinct evolutionary traits such as respiratory mode.

Purpose This paper aims to investigate the different patterns of organizational behavioural responses to major incidents and develop an original classification of these patterns. Design/methodology/approach An extensive literature review was made to investigate the different patterns of behavioural responses to major incidents and then to develop an original classification of these patterns. Several sources of information, such as case studies, technical reports, academic journal articles and organizational internal reports were used. Findings Organizations respond differently to major incidents. This was clear from the different behavioural patterns investigated and identified. Behavioural patterns determine levels of resilience and ability of organizations to overcome and ultimately survive major incidents. Practical implications To promote effective and organized behavioural response patterns to major incidents and improve consistency of responses across the organization, relevant authorities should demonstrate to all private and public enterprises the significance of effective behavioural responses, thus enabling them to better respond to various potential emergencies. Originality/value A number of models of human behaviour have been introduced in the literature to understand how people respond to emergency situations. They each take a different perspective on human behaviour but no single theory has emerged as the leading paradigm. This highlights the complexity of understanding human behaviour in such situations and the need for a better classification of behavioural patterns. To the author’s knowledge, this is one of very few studies to investigate, identify and categorize behavioural response patterns to major incidents. This research is expected to be of a substantial value for those interested in improving organizational behaviour during major incidents, as well as those interested in improving organizational resilience.
