Arid-adapted ungulates species, such as gazelles, have faced tremendous population declines in recent decades. Numerous breeding stations were established across Asia and the Middle East to facilitate the captive breeding of endangered gazelle species. We intended to improve the feed quality of goitered gazelle (Gazella subguttorosa) in captivity at the Kızılkuyu Gazelle Breeding Station in Şanlıurfa Province in southern Turkey. In a feed choice experiment, five different types of supplementary feed were offered to the gazelles (black barley, white barley, forage wheat, white barley flake and a combination of black barley and white barley flake). Statistical analysis revealed a significant difference between the amount of feed types consumed. The mixture of black barley and white barley flake was the most preferred feed type. Black barley alone was the least preferred feed type, while white barley flake was the second most consumed feed, suggesting that white barley flake was particularly attractive to the gazelles. However, nutrient content analysis revealed no significant difference between feed types. When feed consumption was examined between sampling days, a significant difference was unravelled between day 1, 2, 8 and day 3–7. Results were discussed with respect to improving the gastro-intestinal health of captive gazelles, which is imperative when choosing suitable individuals for reintroduction, which should be in good physical condition to increase the chances for survival in the wild.

In the wild, most animals experience daily fluctuations in threats and resources that are synchronised with environmental time cues such as the light-dark cycle. Consequently, animals have evolved daily behavioural patterns (i.e., diurnal or nocturnal) that enhance their fitness by, for example, reducing the temporal overlapping with predators. In fish, previous studies revealed stronger physiological stress responses during the resting period of the species. However, little is known about the circadian modulation of stress indicators and how they are influenced by daily behavioural patterns. In this research, we investigated the behavioural stress responses of two farmed fish species with different activity patterns: the diurnal Nile tilapia (Oreochromis niloticus) and the nocturnal tench (Tinca tinca). To this end, we examined the behavioural response of individuals exposed to the diving test every 4 h over a 24 h cycle (n = 12 fish/species/time point). Results indicated that most behavioural indicators varied according to the time of day, aligning with the daily rhythmic pattern of the two species. Tilapia exhibited stronger stress responses to novelty during the dark phase, while tench displayed higher stress during the light phase. This was supported by stress-related behaviours such as freezing and erratic movements (in both tilapia and tench) and bottom-dwelling (in tench only). These results indicated that stress responses peaked during the resting phase of each species, although behavioural indicators exhibiting this daily variation did not completely coincide between the studied species. Overall, these findings suggest interspecific differences in the daily modulation of behavioural stress indicators in farmed fish, an effect with potential relevance for welfare. Understanding the activity rhythmic patterns, resting periods, and associated daily variation in stress for each fish species of interest can precisely help tailor farming procedures to minimise suffering.

Prior research has demonstrated that animal vocalizations and music can elicit emotional responses in dogs, but their preferences for different acoustic stimuli remain underexplored. This study aimed to develop a methodology to assess dogs’ preferences and behavioral reactions to various acoustic stimuli and examine the role of familiarity in shaping these responses. In the first experiment, 90 pet dogs were exposed to one of six types of sound stimuli: conspecific agonistic vocalizations, conspecific vocalizations recorded in positive contexts, classical music, relaxing music, dog-directed speech, and neutral background noise. The setup involved a room virtually divided into two areas, in which the dog could freely move. Sounds were turned on or off, depending on which of the two zones the dog was in, thereby giving subjects the possibility to choose whether to be exposed to the sound or not. Preferences were determined by relative amount of time spent in the sound versus quiet zone and behaviors were analyzed for emotional indicators. Dogs actively avoided agonistic vocalizations exhibiting increased attention-seeking behaviors toward their owners. No distinct preferences or aversions emerged for the other stimuli, although conspecific vocalizations in positive contexts and dog-directed speech elicited dogs’ attention. Both types of music resulted in lower attention towards the sound compared to the neutral condition. In Experiment 2, the same procedure was used with 20 dogs, half of whom were routinely exposed to classical music at home, to test whether familiarity with classical music affected behavioral responses and preferences. Although no significant behavioral changes or preferences for classical music were observed, dogs with prior exposure spent twice as much time in the sound zone compared to those without, suggesting enhanced likability due to familiarity. These dogs also exhibited more relaxed behaviors, indicating that familiarity may influence emotional responses.
Overall, the study introduces a novel approach for evaluating dogs' preferences for acoustic stimuli. It revealed that none of the stimuli allegedly inducing positive emotions led to a clear preference. However, behavioral data suggest that familiarity can enhance the likability of specific sounds. These findings highlight the need for further investigation into how different soundscapes influence dogs' emotions and behavior over time, and whether dogs may inherently prefer silence. Moreover, the results underscore the importance of carefully considering acoustic enrichment strategies, particularly the role of familiarization in shaping dogs' responses to their auditory environment.
先前的研究表明,动物发声和音乐可以引起狗的情绪反应,但狗对不同声音刺激的偏好仍未得到充分探索。本研究旨在开发一种方法来评估狗对各种声音刺激的偏好和行为反应,并研究熟悉程度在形成这些反应中的作用。在第一项实验中,90 只宠物狗受到了六种声音刺激中的一种刺激:同类激动的发声、同类在积极情境下的发声、古典音乐、放松音乐、狗引导的讲话和中性背景噪音。测试设置是将一个房间实际分为两个区域,狗可以在其中自由活动。声音的开启或关闭取决于狗在两个区域中的哪一个,因此受试者可以选择是否接触声音。根据狗在声音区和安静区所花费的相对时间来确定狗的偏好,并对狗的行为进行情绪指标分析。狗会主动回避煽动性的发声,表现出更多寻求主人关注的行为。对其他刺激物没有明显的偏好或厌恶,尽管在积极情境下的同类发声和狗引导的语言会引起狗的注意。与中性条件相比,两种类型的音乐都会降低狗对声音的注意力。在实验 2 中,我们对 20 只狗进行了相同的实验,其中一半狗在家中经常接触古典音乐,以测试对古典音乐的熟悉程度是否会影响狗的行为反应和喜好。虽然没有观察到明显的行为变化或对古典音乐的偏好,但与没有接触过古典音乐的狗相比,接触过古典音乐的狗在声音区域停留的时间是没有接触过的狗的两倍,这表明由于熟悉古典音乐,狗对古典音乐的喜爱程度有所提高。总之,这项研究为评估狗对声音刺激的偏好引入了一种新方法。总之,该研究引入了一种新方法来评估狗对声音刺激的偏好,结果显示,没有一种据称能诱发积极情绪的刺激会导致明显的偏好。然而,行为数据表明,熟悉的声音可以提高特定声音的可喜欢性。这些发现突出表明,有必要进一步研究不同的声音环境如何随着时间的推移影响狗的情绪和行为,以及狗是否天生喜欢安静。此外,研究结果还强调了仔细考虑声学强化策略的重要性,尤其是熟悉声音在塑造狗狗对听觉环境的反应中所起的作用。

Environmental enrichment with toys can improve the physical and mental well-being of dogs. Despite dogs’ keen sense of smell, there is little known on how providing scented toys influences owned dog behavior. We investigated whether providing scented toys would influence activity levels (dog activity, toy movement, and play) in owned dogs. Experiment 1 assessed owned dog preference (N=30) between scented (beef, chicken, peanut butter, sausage), and non-scented Playology® plush toys using multiple stimulus without replacement (MSWO) test over 4-days, and measured engagement through ActiGraph GT3X accelerometers over a 72-hour period. Experiment 2 assessed the influence of familiar or novel scented toys on the physical activity and engagement of dogs (N=33), using three equal sized treatment groups: scented familiar (their preferred scented toy from Experiment 1), scented novel (peanut butter scent), and non-scented. Results suggest that MSWO did not predict in-home toy engagement. Dogs did show higher play levels for their most engaging scented toy compared to the non-scented toy, but the specific preferred scent varied by individual dog. Overall activity and play declined with age. In Experiment 2, a habituation effect was observed for dogs in the scented familiar group, as toy movement levels reduced when their preferred scented toy was reintroduced (p = 0.006). While no single scent was preferred across all dogs, individual preference for specific scents increased activity levels, suggesting that personalized enrichment can enhance welfare. Tailoring enrichment practices to individual dog preferences can optimize engagement, while considering the potential impact of habituation.
用玩具丰富环境可以改善狗狗的身心健康。尽管狗的嗅觉很灵敏,但人们对提供香味玩具如何影响狗的行为却知之甚少。我们研究了提供香味玩具是否会影响宠物狗的活动水平(宠物狗活动、玩具移动和玩耍)。实验 1 采用多重刺激无替代(MSWO)测试,在 4 天内评估了宠物狗(N=30)对有香味(牛肉、鸡肉、花生酱、香肠)和无香味 Playology® 毛绒玩具的偏好,并通过 ActiGraph GT3X 加速计测量了宠物狗在 72 小时内的参与度。实验 2 评估了熟悉或新奇的香味玩具对狗(33 只)的体力活动和参与度的影响,使用了三个同等大小的处理组:熟悉香味玩具(实验 1 中狗最喜欢的香味玩具)、新奇香味玩具(花生酱香味)和无香味玩具。结果表明,MSWO 无法预测狗在家中玩玩具的情况。与非香味玩具相比,狗对其最感兴趣的香味玩具的玩耍程度确实更高,但具体的偏好香味因狗而异。随着年龄的增长,总体活动量和游戏量都有所下降。在实验 2 中,熟悉气味组的狗出现了习惯性效应,因为当重新引入它们喜欢的气味玩具时,玩具的活动量会减少(p = 0.006)。虽然没有一种气味是所有狗都喜欢的,但个体对特定气味的偏好会提高活动水平,这表明个性化的强化训练可以提高狗的福利。根据狗狗的个体偏好定制丰富刺激措施可以优化参与度,同时还能考虑到习惯化的潜在影响。

Horses may exhibit evasive and flight behaviors to novel situations. These reactive behaviors threaten the safety of horses, owners, handlers, and riders. Poor handling of these reactions also negatively impacts the animal's behavior and, consequently, its well-being. This study aimed to evaluate the effects of a counterconditioning technique to reduce fear responses in horses through a brief exposure procedure. It was conducted with 20 naive horses (16 females and 4 males) of Quarter Horse and Chilean Creole breeds. A pre-post design with experimental and control groups was used. Two training sessions of seven minutes each were conducted, applying counterconditioning in the experimental group and measuring Partial and Total Exposure responses to the fear-inducing situation, Resistance to Handling, Exploratory Behavior Towards Frightening Situation, Exploratory Behavior Towards Handler, and Heart Rate. Mixed ANOVAs were used to analyze the effects of counterconditioning on each dependent variable. The experimental group showed significantly lower resistance to handling compared to the control group (F(1,18) = 5.89, p = 0.02), with a reduction in fear-related reactions (mean decrease of 20 %, SD = 5.6). Additionally, exploratory behavior towards the handler increased significantly in the experimental group (F(1,18) = 6.34, p = 0.019), suggesting a shift in focus from the fear-inducing stimulus to the handler. Heart rate differences were not statistically significant (p > 0.05). These results suggest that counterconditioning can reduce resistance and promote positive human-animal interactions during exposure to fear-inducing stimuli. These findings show that counterconditioning operates as an active technique, manifesting effects exclusively when implemented. It also serves as an effective strategy for enhancing a horse’s exposure to novel or fear-inducing situations. The change in behavioral reaction can be attributed to a process of re-evaluative learning, in which horses shift their focus towards the positive stimuli provided by humans, reducing the prior negative association with fear-inducing situations. Reducing resistance behaviors and guiding the horse's attention toward the favorable aspects of human interaction holds significant importance for ensuring safe exposure and reinforcing the bond between humans and animals. An alternative approach explores appetitive stimulation as a reinforcer for coping, exposure, and collaborative behavior, influencing motivation and bonding. Ultimately, preliminary findings suggest that the appetitive technique positively impacts proximity to humans, indicating the potential for a secure horse-handler relationship. Further research is needed to assess this technique's long-term effects and nuances on the human-animal bond within the context of horses.
马匹在遇到新情况时可能会表现出逃避和逃跑行为。这些反应行为会威胁马匹、马主、饲养员和骑手的安全。对这些反应处理不当也会对动物的行为产生负面影响,进而影响其健康。本研究旨在评估反条件技术的效果,通过短暂的暴露程序减少马匹的恐惧反应。研究对象是 20 匹天真马(16 匹雌马和 4 匹雄马),分别为四分马和智利克里奥尔马品种。采用实验组和对照组的前后设计。共进行了两次训练,每次7分钟,在实验组中使用反条件反射,并测量了马匹对恐惧诱发情况的部分和全部暴露反应、对处理的抵触情绪、对恐惧情况的探索行为、对处理者的探索行为和心率。混合方差分析用于分析反调节对各因变量的影响。与对照组相比,实验组对处理的抵触情绪明显降低(F(1,18) = 5.89,P = 0.02),与恐惧相关的反应也有所减少(平均减少 20%,SD = 5.6)。此外,实验组对饲养者的探索行为显著增加(F(1,18) = 6.34, p = 0.019),这表明饲养者的注意力从恐惧刺激转移到了饲养者身上。心率差异无统计学意义(p > 0.05)。这些结果表明,在暴露于恐惧诱导刺激的过程中,反条件训练可以降低动物的抵抗力,促进人与动物之间的积极互动。这些研究结果表明,反条件反射是一种积极的技术,只有在实施时才会产生效果。同时,它也是一种有效的策略,可帮助马匹更好地适应新奇或恐惧的环境。行为反应的改变可归因于重新评价学习的过程,在这一过程中,马匹会将注意力转移到人类提供的积极刺激上,从而减少之前与恐惧诱导情境的负面联系。减少马匹的抗拒行为,引导马匹关注人与马互动的有利方面,对于确保安全接触马匹和加强人与动物之间的联系具有重要意义。另一种方法是将食欲刺激作为应对、暴露和合作行为的强化剂,从而影响动机和联系。最终,初步研究结果表明,食欲刺激技术对接近人类有积极影响,表明有可能建立一种安全的驯马师关系。还需要进一步的研究来评估这种技术的长期效果以及在马匹中人与动物关系的细微差别。

Behavioural responses of prey to predation can be used as a management tool in breeding systems where rodents cause economic losses and pose a health risk for humans and domestic animals. In this work we assessed the effect of cat fur and TMT odours on food consumption and activity of rodents in poultry farms of the Buenos Aires Province, Argentina. The study was conducted in 8 poultry farms that are devoted to breeding broiler chickens. At each farm we randomly selected three sheds, which were assigned to TMT, cat fur odour or control treatments. Odours were applied on a 5 ×5 cm piece of cloth that was either placed inside feeders or over footprint tracking tiles. Food consumption was measured in each shed at 20 stations with 10 g of wheat seeds, while rodent activity was measured in 10 footprints tracking tiles. Both feeders and footprint tracking tiles were placed outside sheds along walls. Food consumption and activity were assessed 2, 4 and 6 days after the application of treatments. The odour of cat fur caused a reduction in food consumption by rodents, but there was not a significant effect on activity. We did not detect an effect of TMT neither on food consumption, nor in activity. We conclude that cat fur has the potential to be used as repellent for commensal rodents in field conditions. However, its application for large-scale rodent control requires the development of a product that incorporates the active substance responsible for the aversion effect.
在啮齿动物造成经济损失并对人类和家畜健康构成威胁的养殖系统中,猎物对捕食的行为反应可用作一种管理工具。在这项工作中,我们评估了猫皮毛和 TMT 气味对阿根廷布宜诺斯艾利斯省家禽养殖场中啮齿动物食物消耗和活动的影响。研究在 8 个专门饲养肉鸡的家禽养殖场进行。我们在每个农场随机选取了三个禽舍,将其分别分配给 TMT、猫毛气味或对照组处理。气味涂抹在一块 5 × 5 厘米的布上,布被放置在饲喂器内或脚印跟踪瓦上。在每个棚舍中的 20 个站测量食物消耗量,每个站测量 10 克小麦种子的消耗量,同时在 10 块脚印跟踪瓷砖上测量啮齿动物的活动量。喂食器和足迹跟踪瓦片都放在棚外的墙边。在施药后 2、4 和 6 天对食物消耗量和活动量进行评估。猫毛的气味导致啮齿动物的食物消耗量减少,但对活动量没有显著影响。我们没有发现 TMT 对啮齿动物的食量和活动有影响。我们的结论是,猫毛有可能在野外条件下用作共生啮齿动物的驱避剂。不过,要将猫毛用于大规模的鼠类控制,还需要开发一种含有产生厌恶效应的活性物质的产品。

Dogs’ learning performance is influenced by various factors, including training style and post-learning sleep. Family dogs naturally display a large variation in their inattention and impulsivity, traits that can affect both their behaviour and learning outcomes. In this study, we conducted a complementary analysis on the dataset from Reicher et al. (2024) to investigate the effect of dogs' inattention and impulsivity on their behaviour and learning performance. We also revealed to what extent the dogs’ training level, and the owner’s strictness influence the results. Family dogs (N=25) were trained under both Permissive and Controlling conditions in a counterbalanced within-subject design. Each training session was followed by a learning performance test, a two-hour sleep session, and a post-sleep retest. Owner-rated inattention and impulsivity scores were retained from a validated questionnaire (DAFRS). More impulsive dogs tended to learn slightly faster, regardless of the training condition. Dogs with higher inattention scores performed better during the pre-sleep test on the second training occasion (regardless of the condition) and in the post-sleep retest under the Controlling condition. In the Permissive condition, less inattentive dogs showed greater performance improvement from pre- to post-sleep. Furthermore, dogs with stricter owners performed better in the retest, regardless of the training condition, while the dogs’ training level did not affect their performance. Our results revealed complex interactions between training style, training order, sleep, and dogs’ impulsivity and inattention. Some advantages of more impulsive and inattentive dogs may be less surprising considering our typical dog sample, not including individuals with extremely high inattention or impulsivity scores. Although dogs performed better on the first training occasion (Reicher et al., 2024), more inattentive dogs seemed to be less affected by proactive interference (prior learned information impeding subsequent learning within a similar context) on the second session, and they appeared to benefit from a Controlling training style and the repetitive nature of the training procedure. These findings suggest that the effectiveness of different training styles depends on individual dog traits, such as inattentiveness.
狗狗的学习成绩受多种因素的影响,包括训练方式和学习后的睡眠。家犬在注意力不集中和冲动方面自然会表现出很大的差异,这些特征会影响它们的行为和学习效果。在本研究中,我们对 Reicher 等人(2024 年)的数据集进行了补充分析,以研究狗的注意力不集中和冲动对其行为和学习成绩的影响。我们还揭示了狗的训练水平和主人的严格程度对结果的影响程度。我们对家犬(25 只)进行了 "放任 "和 "控制 "两种条件下的训练,并在受试者内部进行了平衡设计。每次训练后都会进行学习成绩测试、两小时睡眠测试和睡眠后复测。狗主人评定的注意力不集中和冲动性得分均来自一份有效的问卷(DAFRS)。无论训练条件如何,冲动型犬的学习速度往往略快。注意力不集中得分较高的狗狗在第二次训练的睡前测试(无论训练条件如何)和控制条件下的睡后复测中表现较好。在 "放任 "条件下,注意力不集中程度较低的狗从睡前到睡后的表现都有较大提高。此外,无论训练条件如何,主人要求较严格的犬在复测中表现较好,而犬的训练水平并不影响其表现。我们的研究结果揭示了训练方式、训练顺序、睡眠与狗的冲动性和注意力不集中之间复杂的相互作用。考虑到我们的典型犬只样本中不包括注意力不集中或冲动性得分极高的个体,冲动性和注意力不集中的犬只的一些优势可能并不那么令人惊讶。虽然狗在第一次训练中表现较好(Reicher 等人,2024 年),但注意力不集中的狗在第二次训练中受主动干扰(先前学习的信息在类似情境中阻碍后续学习)的影响似乎较小,它们似乎从控制型训练风格和训练过程的重复性中获益。这些研究结果表明,不同训练方式的有效性取决于狗的个体特征,如注意力不集中。

This study aimed to assess the effects of prepartum milking training of primiparous goats on behavior, plasma cortisol concentration, and milk yield and quality traits. Thirty-one primiparous Saanen goats were assigned into two treatments: CT = milking-trained (n = 16) and ST = not milking-trained (n = 15) goats. Milking training consisted of the handler entering the pen where the goats were and walking calmly among them for 20 minutes/day for seven days, and then driving the goats to the milking parlor, positioning them in the stanchion, and gently touching their ribs, legs, and udders for five minutes for seven days. Behavioral assessments were carried out measuring the latency that each goat took to get close to a known person (voluntary approach = LC) and the flight distance (FD) before training (BT), just after training (AT), at the beginning (between days five and seven, d5–7) and 30 days of lactation (d30). Milking reactivity was assessed by recording the step-kick (SK) and head, ear and tail movement (MOV) scores. Plasma cortisol concentrations (PCC) were measured after milking. All measurements were recorded at 5–7 (d5–7), 30 (d30), and 60 (d60) days of lactation, defining the assessment days. The number of animals that required restraint during milking was also recorded. Milk yield was recorded daily throughout the 120 days of the lactation period, and milk quality traits (dry matter, density, fat, protein, lactose, minerals, acidity, SCC, Staphylococcus and total bacterial count - TBC) at d5–7, d30, d60, d90, and d120. The goats’ reactivity decreased throughout lactation. CT goats showed a lower LC on d30 than before training. PCC showed higher values on d60 than prepartum. At the beginning of lactation, 73 % of ST goats were restrained for milking, while for CT goats, 45 %. Milk yield was highest in the period from 8 to 90 days of lactation and 0.5 kg/day higher (although not significant) in CT than in ST. Milk quality traits showed significant differences between assessment days, except for TBC and Staphylococcus counts. In conclusion, the training protocol did not significantly impact goats' reactivity during milking, PCC, and milk quality traits. However, there was a tendency to increase milk yield and reduce the number of animals restrained during milking.
本研究旨在评估初产山羊产前挤奶训练对其行为、血浆皮质醇浓度、产奶量和牛奶质量性状的影响。31 只初产萨能山羊被分为两个处理:CT = 接受过挤奶训练的山羊(n = 16),ST = 未接受过挤奶训练的山羊(n = 15)。挤奶训练包括:饲养员进入山羊所在的圈舍,在山羊中间平静地走动,每天20分钟,持续7天;然后将山羊赶到挤奶厅,将它们放在挤奶台上,轻轻触摸它们的肋骨、腿和乳房,持续5分钟,持续7天。行为评估是在训练前(BT)、训练后(AT)、泌乳初期(第五天和第七天之间,d5-7)和泌乳 30 天(d30)测量每只山羊接近已知人的潜伏期(自愿接近 = LC)和飞行距离(FD)。挤奶反应性通过记录步踢(SK)和头、耳、尾运动(MOV)得分进行评估。挤奶后测量血浆皮质醇浓度(PCC)。所有测量均记录在泌乳 5-7 (d5-7)、30 (d30) 和 60 (d60) 天,即评估天数。此外,还记录了挤奶过程中需要束缚的动物数量。在泌乳期的 120 天内,每天记录牛奶产量,并在第 5-7 天、第 30 天、第 60 天、第 90 天和第 120 天记录牛奶质量特性(干物质、密度、脂肪、蛋白质、乳糖、矿物质、酸度、SCC、葡萄球菌和细菌总数 - TBC)。山羊的反应性在整个哺乳期都有所下降。与训练前相比,CT 山羊在第 30 天的 LC 值较低。PCC山羊在第60天的LC值高于产前。在泌乳初期,73% 的 ST 山羊在挤奶时受到约束,而 CT 山羊只有 45%。泌乳期 8 至 90 天的产奶量最高,CT 比 ST 高 0.5 千克/天(尽管不显著)。除 TBC 和葡萄球菌计数外,牛奶质量性状在不同评估日之间存在显著差异。总之,训练方案对山羊挤奶时的反应性、PCC和牛奶质量性状没有显著影响。不过,有增加产奶量和减少挤奶期间受限动物数量的趋势。

The welfare of zoo animals has come under increasing scrutiny, yet the effects of visitors on captive species, particularly in relation to environmental factors and individual variability, remain insufficiently studied. This study introduces a novel methodology to assess how visitors influence the social and spatial dynamics of Western lowland gorillas (Gorilla gorilla gorilla) in naturalistic enclosures. We conducted daily observation sessions to track the positioning of gorillas relative to one another and their environment. Key visitor-related factors such as mere presence, density, movement and activity along two independent paths, adjacent to the enclosure were recorded and related to the gorillas' spatial distribution. Two indices – the Retreat Index (RI) and the Exposure Tolerance Index (ETI) – were developed to quantify each individual’s tendency to retreat from exposed areas or tolerate visitor observation. For the first time, Ripley's functions were employed to assess changes in distribution patterns among individuals in response to visitor presence. Our results show that visitor pressure significantly reduces inter-individual distances, a trend further amplified by environmental factors such as wind, temperature, and humidity. Among visitor-related variables, movement of new visitors, rather than mere presence or crowd size, was the primary factor triggering behavioural changes. Social network analysis revealed increased interactions, particularly between females and their offspring, along with enhanced comfort and resting behaviours in the presence of visitors. Additionally, we observed a dichotomy in the gorillas' behavioural response, with less pronounced reactions in areas where visitors were less visible. Ripley's functions identified substantial aggregation of gorillas in visitor-influenced scenarios, in contrast to a near-random distribution when visitors were absent. This pilot study establishes a foundation for developing a comprehensive methodology, applicable across various zoo settings, to evaluate the impact of visitor-induced disturbances on gorillas, offering fresh insights into the welfare of captive animals.
动物园动物的福利受到了越来越多的关注,但游客对圈养物种的影响,特别是与环境因素和个体差异有关的影响,仍然没有得到充分的研究。本研究采用一种新颖的方法来评估游客如何影响自然围栏中西部低地大猩猩(大猩猩)的社会和空间动态。我们每天进行观察,跟踪大猩猩相对于彼此及其环境的位置。我们记录了与访客相关的关键因素,如大猩猩在围栏附近两条独立路径上的存在、密度、移动和活动情况,并将其与大猩猩的空间分布联系起来。制定了两个指数--退避指数(RI)和暴露耐受指数(ETI)--来量化每个个体从暴露区域退避或容忍游客观察的倾向。我们首次使用里普利函数来评估个体间的分布模式因游客的存在而发生的变化。我们的研究结果表明,游客的压力大大减少了个体间的距离,而风、温度和湿度等环境因素又进一步放大了这一趋势。在与游客相关的变量中,新游客的移动是引发行为变化的主要因素,而不仅仅是游客的存在或人群的规模。社会网络分析显示,在有访客存在的情况下,动物之间的互动,尤其是雌性动物与后代之间的互动会增加,同时动物的舒适感和休息行为也会增强。此外,我们还观察到大猩猩行为反应的两极分化,在游客较少的区域,大猩猩的反应不太明显。里普利函数发现,在游客影响的情况下,大猩猩会大量聚集,而在没有游客的情况下,大猩猩的分布则近乎随机。这项试点研究为开发适用于各种动物园环境的综合方法奠定了基础,该方法可用于评估游客引起的干扰对大猩猩的影响,为圈养动物的福利提供了新的见解。

With increasing public concern for farm animal welfare, understanding their current welfare status is paramount. Animal welfare can be inferred from their behaviour, as behaviour represents the combination of internal and external cues. The aims of this study were to quantify a behavioural baseline for group-housed, pre-weaned dairy calves that were reared under conventional management conditions, and to determine how different internal (i.e. age) and external (i.e. temperature) factors affected this behaviour. Female dairy calves (n=47) were allocated to 1 of 3 pens based on birth date and reared under conventional Irish management conditions; after 3–4 d in individual pens, calves were moved into group pens where they had ad libitum access to water, concentrates, and forage (first barley straw, then hay). Milk replacer (6 L/d) was fed through an automatic milk feeder; calves were gradually weaned from day 42–84. A 24 h period/week of video recording was used for behaviour scoring for 8 consecutive weeks (scan sampling at 10-min intervals). Behaviours included posture (lying or standing) and activity (17 behaviours). Calves were scored for clinical health twice weekly and only healthy calves were used in the analysis (n=39). Behaviour proportions were analysed using generalised linear mixed models. Proportion of time spent lying decreased as calves aged (week 1 vs. 9; percentage mean ± standard deviation; 79.8 ± 4.04 vs. 72.1 ± 6.52 %; P=0.004), while time spent ruminating (2.0 ± 2.51 vs. 14.1 ± 8.72 %; P<0.001), eating bedding (0.8 ± 1.16 vs. 6.1 ± 4.66 %; P<0.001), eating forage (0.9 ± 1.20 vs. 1.8 ± 1.81 %; P=0.007), and eating concentrates (0.5 ± 1.15 vs. 2.2 ± 1.72 %; P=0.018) increased with age. On days when the minimum shed temperature was <4°C compared to >6°C, calves spent more time lying (75.9 ± 5.27 vs. 72.3 ± 5.78 %; P<0.001) and less time eating concentrates (0.8 ± 1.11 vs. 1.4 ± 1.49 %; P=0.035), eating forage (0.8 ± 0.91 vs. 1.5 ± 1.57 %; P=0.005), eating bedding (2.7 ± 2.87 vs. 4.0 ± 4.78 %; P=0.003), and walking (1.5 ± 1.20 vs. 2.0 ± 1.40 %; P=0.017), independent of age. These findings provide a normal behaviour baseline for future calf behaviour studies and highlight potential areas of improvement in current, conventional calf rearing practices.
随着公众对农场动物福利的关注与日俱增,了解其福利现状至关重要。动物福利可以从它们的行为中推断出来,因为行为代表了内部和外部线索的结合。本研究的目的是量化在传统管理条件下饲养的群居断奶前乳牛的行为基线,并确定不同的内部因素(如年龄)和外部因素(如温度)对这一行为的影响。雌性奶牛犊牛(47 头)根据出生日期被分配到 3 个栏中的 1 个,在爱尔兰传统管理条件下饲养;在单个栏中饲养 3-4 天后,犊牛被转移到集体栏中,在集体栏中,犊牛可以自由取用水、精料和饲料(首先是大麦秸秆,然后是干草)。代乳品(6 升/天)通过自动喂奶器喂给;犊牛从第 42-84 天开始逐渐断奶。连续 8 周每周 24 小时的视频记录用于行为评分(每隔 10 分钟扫描取样一次)。行为包括姿势(躺或站)和活动(17 种行为)。每周两次对犊牛的临床健康状况进行评分,只有健康的犊牛才被用于分析(n=39)。行为比例采用广义线性混合模型进行分析。随着犊牛年龄的增长,躺卧时间比例减少(第 1 周 vs. 第 9 周;百分比平均值 ± 标准差;79.8 ± 4.04 vs. 72.1 ± 6.52 %;P=0.004),而反刍时间(2.0 ± 2.51 vs. 14.1 ± 8.72 %;P<0.001)、吃垫料(0.8 ± 1.16 vs. 6.1 ± 4.66 %;P<0.001)、吃草料(0.9 ± 1.20 vs. 1.8 ± 1.81 %;P=0.007)和吃精料(0.5 ± 1.15 vs. 2.2 ± 1.72 %;P=0.018)的时间随着年龄的增长而增加。在最低舍温为 <4°C 的日子里,犊牛躺卧的时间更长(75.9 ± 5.27 vs. 72.3 ± 5.78 %;P<0.001),吃精料的时间更短(0.8 ± 1.11 vs. 1.4 ± 1.49 %;P=0.035)、吃草料(0.8 ± 0.91 vs. 1.5 ± 1.57 %;P=0.005)、吃垫料(2.7 ± 2.87 vs. 4.0 ± 4.78 %;P=0.003)和行走(1.5 ± 1.20 vs. 2.0 ± 1.40 %;P=0.017)的时间较少,与年龄无关。这些发现为今后的犊牛行为研究提供了一个正常行为基线,并突出了当前传统犊牛饲养方法中可能需要改进的地方。

Animal welfare can be inferred from their behaviour, as behaviour represents the combination of internal and external cues. The aims of this study were to quantify a behavioural baseline for group-housed, pre-weaned dairy calves that were reared under conventional management conditions, and to determine how different internal (i.e. age) and external (i.e. temperature) factors affected this behaviour. Female dairy calves (n=47) were allocated to 1 of 3 pens based on birth date and reared under conventional Irish management conditions; after 3–4 d in individual pens, calves were moved into group pens where they had <em>ad libitum</em> access to water, concentrates, and forage (first barley straw, then hay). Milk replacer (6 L/d) was fed through an automatic milk feeder; calves were gradually weaned from day 42–84. A 24 h period/week of video recording was used for behaviour scoring for 8 consecutive weeks (scan sampling at 10-min intervals). Behaviours included posture (lying or standing) and activity (17 behaviours). Calves were scored for clinical health twice weekly and only healthy calves were used in the analysis (n=39). Behaviour proportions were analysed using generalised linear mixed models. Proportion of time spent lying decreased as calves aged (week 1 vs. 9; percentage mean ± standard deviation; 79.8 ± 4.04 vs. 72.1 ± 6.52 %; P=0.004), while time spent ruminating (2.0 ± 2.51 vs. 14.1 ± 8.72 %; P&lt;0.001), eating bedding (0.8 ± 1.16 vs. 6.1 ± 4.66 %; P&lt;0.001), eating forage (0.9 ± 1.20 vs. 1.8 ± 1.81 %; P=0.007), and eating concentrates (0.5 ± 1.15 vs. 2.2 ± 1.72 %; P=0.018) increased with age. On days when the minimum shed temperature was &lt;4°C compared to &gt;6°C, calves spent more time lying (75.9 ± 5.27 vs. 72.3 ± 5.78 %; P&lt;0.001) and less time eating concentrates (0.8 ± 1.11 vs. 1.4 ± 1.49 %; P=0.035), eating forage (0.8 ± 0.91 vs. 1.5 ± 1.57 %; P=0.005), eating bedding (2.7 ± 2.87 vs. 4.0 ± 4.78 %; P=0.003), and walking (1.5 ± 1.20 vs. 2.0 ± 1.40 %; P=0.017), independent of age.
