“…The sequence of behaviors that occur over a period of time constitutes an important source of information, pointing to the effects of the environment on the birds. It is of great value to have the possibility of applying an appropriate technique to monitor the behavior of birds in their rearing environment and, with this, have the opportunity to perform an accurate analysis regarding their behavioral pattern (Saltoratto et al, 2013).…”

The objective of this study was to develop a software based on image processing and computer vision techniques for monitoring the feeding/collective behavior of broilers (Cobb) and validate it based on the results obtained from the visual analysis of an expert. The visual analysis was performed based on the observation and quantification of behaviors in the interval of 10 min at each hour of the day, in the period of 24 hours, totaling 1728 frames/day, for males and females. The software was developed using the Hoshen-Kopelman algorithm, for labeling clusters, which would basically be the grouping of similar pixels. This software is written in the 1999 standard of the C language. After this stage of programming, the Hoshen-Kopelman algorithm identified the birds in the region of interest (feeder and drinker), with removal of the background color to obtain the descriptors, using the same range of visual analysis. Then, the software was validated through linear regression analysis, using the R platform. Based on the correlation analyses, it was found that the coefficient of determination (R²) ranged from 0.74 to 0.97 for all software validation events. The number of broilers in the regions of interest showed R² above 0.70 for females and above 0.89 for males, which allowed the characterization of the ingestive behavior of broilers by computer vision. Some factors that caused interference in the accuracy of the software were decisive for the result, especially the arrangement of the cameras, uneven lighting, obstruction caused by the lighting system, pendular movement of the feeders and drinker, and shade generated by them. Despite the highlighted interferences, the results allowed us to infer that the software identified and quantified the feeding behavior of broilers in an appropriate manner.

“…Os efeitos do local de criação e produção sobre os animais podem ser analisados através da avaliação do seu comportamento ao longo de um tempo determinado, sendo importante, para isso, a utilização de técnicas corretas para o monitoramento do comportamento animal, buscando uma análise mais precisa a respeito desses padrões comportamentais (SALTORATTO et al, 2013). Um dos principais sinais que serve como indicador de falhas no sistema produtivo é o comportamento anormal dos animais, que deve ser diagnosticado em estágio inicial, evitando, assim, prejuízos maiores ao seu bem-estar e para sua produtividade.…”

O bem-estar animal é um assunto amplamente discutido na cadeia de produção. Nesse contexto surge a etologia, que é a ciência que estuda o comportamento animal, colaborando para melhor entender o animal em seu sistema de produção. Os estudos comportamentais da população avícola iniciam em sua organização social na natureza, procurando estudar fenômenos ligados à dominância e à submissão entre machos e fêmeas, organização familiar e domínio de território, entre outros fatores. A prática dessa ciência dá origem ao etograma, que é um registro por meio de observações do comportamento animal frente aos estímulos externos que evocam seus diferentes componentes. Dessa forma, o presente trabalho bibliográfico visa avaliar os aspectos comportamentais e produtivos dos animais com enfoque na avicultura, buscando entender a melhor aplicação dos etogramas para identificação do bem-estar animal. Esta ferramenta é importantíssima para que se descubram todas as potencialidades de cada espécie ou gênero animal estudado, oferecendo subsídios para orientação e exploração consciente pelo homem. O estudo da etologia ultrapassa a curiosidade científica exclusiva da zoologia. Tornou-se necessária para respeitar, além da exigência do mercado consumidor por Boas Práticas de Produção, o bem-estar do animal em foco. A aplicação do etograma se torna essencial para verificação dos comportamentos dos animais visando analisar fatores que possam ser prejudiciais para o bem-estar desses indivíduos e, também, sua produtividade. A implantação deste protocolo na criação de poedeiras comerciais objetiva o norteamento do bem-estar por parte das empresas produtoras e indústrias processadoras de ovos do Brasil. Palavras-chave: Avicultura. Comportamento Animal. Etologia. Abstract Currently, animal welfare is a subject widely discussed in the production chain. In this context ethology arises, which is the science that studies animal behavior, collaborating to better understand the animal in its production system. Behavioral studies of the poultry population begin in its social organization in nature, seeking to study phenomena related to dominance and submission between males and females, family organization and territory domain, among other factors. The practice of this science gives rise to the ethogram, which is a record through observations of animal behavior before external stimuli that evoke its different components. Thus, the present bibliographic study aims to evaluate the behavioral and productive aspects of animals with a focus on aviculture, seeking to understand the best application of ethograms to identify animal welfare. This tool is very important for discovering all the potentialities of each species or animal genus studied, offering subsidies for guidance and conscious exploitation by man. The study of ethology goes beyond the exclusive scientific curiosity of zoology. It became necessary to respect, in addition to the consumer market's demand for Good Production Practices, the animal welfare in focus. The application of the ethogram becomes essential to verify the animals’ behaviors in order to analyze factors that may be harmful to the welfare of these animals and also their productivity. The elaboration of this animal welfare protocol in the creation of commercial laying hens aims at the guide for the production companies and egg processing industries of Brazil, to adjust such needs of welfare assessment. Keywords: Bird Welfare. Animal’s Behavior. Ethology.

“…Digital cameras have been used to monitor the behavior of birds, in which the images analyzed use computer vision techniques [32,[35][36][37]. Computer vision is responsible for extracting relevant information based on images captured by digital cameras, whether through photographic or video images, sensors, and other devices [38].…”

Laying hens are affected by the intensity, wavelength, and duration of light, and the behavioral patterns of these animals are important indicators of stress. The objective of the present study was to evaluate cluster and unrest behaviors of lying hens submitted to three environments with different treatments of monochromatic lighting (blue, green, and red). For 29 weeks, 60 laying hens from the Lohmann variety were divided into three groups and monitored by surveillance cameras installed on each shed ceiling and directed to the floor. Each group was housed in a small-scale shed and maintained under a monochromatic lighting treatment. The recordings were made at two times of the day, 15 min in the morning and 15 min in the afternoon, and the videos were processed, segmented, and analyzed computationally. From the analysis of the images, the cluster and unrest indexes were calculated. The results showed the influence of lighting on these behaviors, displaying that the birds were more agitated in the treatments with shorter wavelengths. Cluster behavior was higher in birds housed under red light. There was an interaction between the lighting treatments and the thermal environment, indicating that more studies should be carried out in this area to better understand these behavioral changes.
