Laboratory fish play an important role in many research fields, and they are also raised and bred in many laboratories around the world. While many studies have suggested suitable feeding densities for various laboratory fish, significant variations exist in the sizes of rearing tanks across different laboratories. Moreover, there is limited research on the effects of different rearing tank sizes. In this study, we set up the same rearing density (one liter of water corresponding to two fishes) and four treatments with different tank sizes (5 L, 10 L, 15 L, 20 L)...

An overabundance of wild horses and burros on federal lands can lead to suboptimal welfare when there are insufficient forage and water resources. Placing some of these animals in private homes has been identified as a key part of the solution. A nationwide online survey completed by 2,247 current and former horse owners is used to assess the feasibility of accommodating this strategy. The survey tool addressed basic horse ownership and demographic information, previous experience with wild horses, and hypothetical wild horse adoption scenarios...

When necessary, sea turtles are held captive for veterinarian care and research purposes. Protocols and basic guidelines have been described for husbandry of sea turtles with veterinarian needs but not considering physiological indicators of animal welfare. Because all sea turtle are imperiled species, monitoring their welfare is important. The aim of this study was to standardize husbandry protocols for loggerhead ( Caretta caretta ) juveniles held under seminatural conditions, based on circulating concentration of plasma corticosterone (Cort) and behavior...

Cognitive biases reveal underlying affective state by indicating optimism and pessimism. This methodology may permit assessment of positive welfare in animals that have few validated positive welfare indicators, such as bears. Our goal was to validate a judgment bias test for assessing optimism in brown bears, using a touchscreen. After training the bears on a conditional discrimination, we compared responses to an ambiguous stimulus in a 2 × 2 nested design involving four experimental conditions representing presence or absence of a behind-the-scenes tour and presence or absence of a keeper training session with food reinforcement...

Staying in animal shelters can be stressful for dogs because of exposure to noise, unfamiliar environment, and social separation. Consequently, the wellbeing of sheltered dogs could be improved through reduction of length of stay in a shelter (LOS). To help inform the development of interventions aimed at LOS reduction, we analyze dogs' characteristics affecting their LOS. We use econometric modeling to identify the characteristics's influence by simultaneously controlling for multiple factors. We use data from Poland's largest animal shelter (11805 observations from the years 2000-2020)...

Keystone individuals are expected to disproportionately contribute to group stability. For instance, rhesus macaques ( Macaca mulatta) who police conflict contribute towards stability. Not all individuals' motivations align with mechanisms of group stability. In wild systems, males typically disperse at maturity and attempt to ascend via contest competition. In a captive system, dispersal is not naturally enabled - individuals attempt to ascend in their natal groups, which can be enabled by matrilineal kin potentially destabilizing group dynamics...

Hippotherapy is considered as a beneficial field of activity for Žemaitukas, a Lithuanian native horse breed. The aim of this study is to analyze the suitability of Žemaitukas breed horses for hippotherapy by using a set of tests based on the temperament, behavioral reactions, and zoometric measurements. Results of these tests inform whether the future use of Lithuanian native horses in hippotherapy can ensure their welfare. In total, 32 horses were evaluated. Twenty-nine of the evaluated horses were horses of the Žemaitukas breed that had never been used for hippotherapy, the others were hippotherapy horses representing different breeds, which were considered the control group...

In mammals, progesterone and estrogens affect the stress response. The study aimed to compare the physiological and behavioral responses to the social isolation of ewes during the estrus or luteal phase. Estrous and diestrous ewes (n = 10 and 8 respectively) were individually isolated in a novel place for 10 min. Ewes' behavior was recorded during the test. Cortisol, blood proteins and glucose concentrations, and the skin surface temperature were determined before and after the test. Cortisol increased immediately after the test ended ( P = 0...

Blood extraction is extremely important for the development of scientific research; however, the existing methods for amphibian´s blood sampling are invasive, mainly leading to the euthanasia of the animal. Therefore, less intrusive methods that allow the obtention of multiple samples from the same individual, are needed as an alternative to the common methods available. Hence, the aim of this study was to propose a minimally invasive method for obtaining blood from the hind leg of Xenopus laevis , that allows continuous sampling without compromising the wellbeing of the organisms...

Civet coffee is produced with coffee beans that have passed through the digestive tract of civets which are then processed for drinking. Outlets, known as civet coffee tourism plantations are popular tourist attractions in Bali, Indonesia. These outlets keep caged civets for public viewing and sell civet coffee. We assessed civet welfare in 29 civet coffee tourism plantations to assess husbandry factors, the five freedoms and body condition scores. We also assessed civet welfare in eight wildlife markets where civets are sourced for civet coffee tourism and calculated turnover of civets...

Benefits and challenges of dogs being present at the office were analyzed from three perspectives: the company view, the dog owner (employee) and the dog view. For companies, office dogs may serve as a branding symbol, leading to higher employee satisfaction and productivity, increased stress resilience and fewer turnover intentions. Yet, companies need to apply pet policies, risk management strategies and mitigate nuisance such as barking, loose fur or excrement. Additional breaks to walk the dogs are required and other employees or customers may be irritated...

Most wild parrot species live in flocks, enriched by the environment and conspecific interactions. Captive parrots often live individually and are prone to behavioral maladaptation. If captive parrots and their behavior become intolerable, they are commonly relinquished to rescue organizations. This study aims to create parrot personality assessments for use by rescuers adding newly acquired parrots to shared environments. The study involved 20 orange-winged Amazon parrots (10 M, 10 F). Observers familiar with each bird scored its personality and analyses determined three sets of personalities: Social, Guarded, and Nervous Each parrot was paired with its 10 heterosexual counterparts and its interactions monitored remotely and captured on video...

The agricultural professionals are ethically obligated to provide good care for the animals under their care. We analysed Brazilian agricultural science students' profiles based on their perceptions of animal welfare (AW). The survey included 239 students from agronomy, animal science, and veterinary courses in 44 universities. A factor analysis and a cluster analysis identified four students' profiles. "The farm animal stewards" group (n= 79) focused their perceptions of AW on basic health and functioning as a basis for meat, wool, egg, and dairy production, while the "the industrial view" group (n= 15), in the profitability and economic factors...

This study researched end-of-life (EoL) decision-making processes in small animal practices in the Netherlands, focusing on strategies veterinarians contemplate during this process. Fourteen veterinarians were interviewed about animal end-of-life decision-making. The results of these interviews show that the decision-making process consists of three steps. The first step is to assess the animal's health and welfare . During the second step, veterinarians consider the position of the owner . Based on steps 1 and 2, veterinarians decide in step 3 whether their advice is to a) euthanize or b) contemplate one or more strategies to come to a decision or potentially alter the decision...

Harnesses have become increasingly popular and whilst there are benefits to harnesses, the impact of harness design on canine biomechanics, and thus physical health and welfare is largely unknown. The purpose of this study was to assess the effect of three popular commercially available harnesses on canine locomotion in 66 domestic dogs. Dogs were filmed moving on a loose lead over a Tekscan Strideway gait analysis system. Stride length as a proportion of limb length (calculated as distance from the elbow to the floor), body weight distribution in the front versus the hind limbs (%), and minimum and maximum apparent angles of the lateral epicondyle of humerus (LEH) and greater tubercle of humerus (GTH) during the motion cycle were measured...

Environmental changes like vet visit could cause stress in cats. Studies have attempted to develop stress management strategies targeting sensory systems. Even though species-appropriate music which includes cat affiliative sound (e.g., cats' purring and suckling sound) has been shown to relieve stress in cats. Little is known whether the cat sound alone works in stress management. This study was conducted to investigate the effects of species-relevant auditory stimuli on stress in cats exposed to a novel environment...
