Influência do enriquecimento ambiental nos padrões comportamentais de Galictis cuja, furão-pequeno, mantidos em cativeiro no zoológico municipal de Piracicaba, SP

Currently zoos and management centers are valuable tools in the maintenance and study of various species. Studies of behavior of captive animals contribute to the improvement of management techniques and the well - being of themselves, encouraging captive breeding and reintroduction also to the natural environment . One of the ways to increase the levels of well-being is the use of environmental enrichment techniques that provide necessary incentives for the welfare of both physical and psychological captive animal . The aim of this study was to identify the types, frequencies and intensities of behavior displayed by three individuals of the species Galictis cuja, belonging to the family Mustelidae and popularly known as lesser grisson , which are captives in municipal zoo in Piracicaba , SP . In addition to evaluating the influence of environmental enrichment techniques on these behavioral parameters. The animals had their behaviors recorded in ethograms through the focal sampling method , 40 hours per person , totaling 120 hours of observation . Were introduced four environmental enrichment techniques related to physical environment, nutrition , perception and cognitive stimulation . At the end, the results of observations before and after the introduction of enrichment techniques were compared and it was possible to observe significant changes in behavior such as run , walk and scratching . The animals were more active and spent longer visible during the day, the enrichment also increased the frequency of social behaviors and the end of the work occurred even attempted copulation , thus showing that the enrichment exerted a positive influence on the behavioral patterns of lesser grisson (Galictis cuja)

Avaliação da influência do enriquecimento ambiental nas variáveis comportamentais de saguis-de-cara-branca (Callithrix geoffroyi) em cativeiro

Six species of the genus Callithrix can be found across the Atlantic Forest extension, being the Callithrix geoffroyi, Geoffroy`s marmoset, the least studied species. The objective of this study is to investigate the behavioral aspects of the species in captivity, and how the environmental enrichment techniques influence those behaviors. To this end, we have studied three specimens of C. geoffroyi, in captivity at Municipal Zoo of Piracicaba, São Paulo. The enclosure includes a 37m2 with under masonry, concrete platforms with external deep, trunks, a floor of grass and soil, e grid in their other three sides. The sampling method was focal per time interval, with records every 30 seconds in sessions of 30 minutes, totaling 30 hours for each animal, which were distributed in a baseline phase, an environmental enrichment phase and post-enrichment phase (n = 3660 records in each phase). The twelve enrichment techniques were applied: the physical environment (branches for perches and hoses fabrics for bedding and vanishing points), cognitive (radio, mirror, puzzle food) and food (insects, flowers and eggs hidden, wrapped). Initially, to determine the period of greatest activity of marmosets, we investigated the pattern of activity for three days (9:00 am to 17:00 pm) consecutively at intervals of 15 minutes, recording the number of active and inactive individuals. The 495 records signaled greater activity in the morning, then selected period for the completion of this work. The ethogram comprised 16 behaviors. The inactivity was the predominant phase behavior baseline and post-enrichment with a significant decrease (h=8,62, p <0.01) in the enrichment phase, and a significant increase in the post enrichment (h=18,15, p <0.001). The same was seen for the use of substrate (grid and ground vs. Trunk and concrete, h=5,09, p <0.001 and h=3,98, p <0.05)... (Complete abstract click electronic access below)

A influência do enriquecimento ambiental no comportamento agressivo da tilápia do Congo Tilapia rendalli

O enriquecimento ambiental tem sido proposto como uma prática para melhoria do bem-estar de animais de cativeiro ou de produções zootécnicas. No caso de animais territoriais e agressivos, ao se enriquecer o ambiente, aumenta-se a quantidade de recursos a se defender, bem como o valor do território em disputa, aumentando as interações agressivas. Esse aspecto foi mostrado recentemente para o peixe ciclídeo tilápia-do-Nilo (Oreochromis niloticus). Do ponto de vista comparativo, isso pode ser um fenômeno espécie-específico. Para avaliar isso devemos observar se em condições similares outro peixe ciclídeo sofre a mesma influência do enriquecimento do ambiente. Assim, seguindo a lógica do confronto obtido para tilápia-do-Nilo, aventamos a hipótese de que as atividades agressivas aumentam em função do enriquecimento. Este estudo avaliou essa hipótese para a tilápia do Congo Tilapia rendalli. Como principal resultado, observamos que a latência para iniciar a luta é menor no ambiente enriquecido, mas a frequência de ataques é maior no ambiente não enriquecido (controle). Além disso, observamos clara definição hierárquica por meio da sinalização de submissão (corpo com listras escuras) e dominância (corpo claro sem listras) na condição sem enriquecimento do ambiente. Concluímos que ao contrário da tilápia-do-Nilo, na tilápia do Congo o enriquecimento do ambiente leva a diminuição da agressividade sem clara definição da hierarquia de dominância

Environmental enrichment reduces aggression of pearl cichlid, Geophagus brasiliensis, during resident-intruder interactions

Em lutas entre peixes residentes e intrusos, residentes geralmente vencem, provavelmente porque valorizam o território mais do que os intrusos. Nós aventamos a hipótese de que ambientes enriquecidos aumentam o valor da área em disputa, levando os residentes a defenderem mais violentamente ambientes enriquecidos de recursos do que ambientes empobrecidos, pois possuiriam mais motivação para mantê-lo. No entanto, no presente estudo, ao testarmos as interações entre intrusos e residentes em acarás, Geophagus brasiliensis, observamos que o enriquecimento ambiental reduz a agressividade e pode levar a cohabitação entre os peixes, sem luta. Adicionalmente, em nossos experimentos, o efeito da residência prévia ocorreu independente da condição de enriquecimento. A diminuição das interações entre os peixes e, consequentemente, a diminuição do nível de agressividade é aqui atribuída aos efeitos da diminuição da visibilidade entre os peixes devido ao aumento de complexidade do ambiente.

O bem-estar animal: como avaliá-lo e promovê-lo

The traffic of wild animals can be identified as the main cause of finding captive animals in zoos and sorting centers in Brazil. The maintenance of these animals in captivity is usually justified by the prevention of total loss of individuals of that specie, if it becomes extinct in the wild, and also, the importance of these subjects in studies of basic biology of the species. Keeping animals in captivity environment brings the need to ensure the welfare of them. The high population density and limited space are some of the possible stressors that these individuals face in capivity. Even the low pressure feeding and food easily available could be stressors, since they change the budget activities typical of the specie, causing sedentary behavior and sometimes depression. The captive environment and activities related to it (handling, transport, social change and social isolation) could compromise the animal welfare. Reduction in life expectancy, impaired growth and reproduction, personal injury, illness, immunosuppression, exacerbated adrenal activity and abnormal behavior, are events often lonked to compromised welfare. Hence, assessment and promoter methods are used to provide the welfare to captive animals. The assessment can be made by hormonal and/or behavioral measures. Both are extremely important, and usually are used in combination, to provide more tangible results about the condition of the animal. The promotion of animal welfare can be accomplished through environmental enrichment, a technique which aims to provide a more complex and diverse environment, increasing the possibility of the animal express more natural behavior, or characteristic of the species. Thus, the objective of this dissertation is discuss the importance of animal welfare and the ways this can be evaluated and promoted... (Complete abstract click electronic access below)

Síndrome da disfunção cognitiva em cães

Cognitive dysfunction syndrome (CDS) is a progressive degenerative disorder of older dogs, characterized by a decline in cognitive function. The main clinical signs consistent with CDS are: disorientation, changes in socio-environmental interaction, sleep-wake cycle disturbance, changes in hygiene habits, urinate and/or defecate in unusual places, decreased physical activity, anxiety and eating disorders. There are no specific diagnostic tests for this condition in vivo, but alterations in neurological examination, cognitive tests and magnetic resonance imaging can be observed. The diagnosis is confirmed by histopathological examination of brain tissue. Diets rich in antioxidants, environmental enrichment with exercise and the use of selegiline and L-deprenyl have been recommended for the treatment of CDS.
