Teaching community requires more than transmitting a set of skills or technical knowledge. It is perhaps one of the greatest challenges of the twenty-first century. This paper contributes to the pedagogy of community in higher education through the analysis of university extension in Brazil. Three elements are crucial to the success of the Brazilian university extension model to teach community. The first is the historical commitment to ethical and political principles and values aimed at social justice, inclusion, and transformation, as well as a shared critical understanding of the complexity of social, economic, and political inequality. Second, the method is derived from critical theory, primarily in the form of Freirean pedagogy, as well as participant and action research. Third, the institutionalization of university extension through the Ministry of Education has provided the necessary means and support at the local, regional, and national levels. Latin America has a unique model of university extension that was developed in the twentieth century, with significant contributions from student movements. Liberation theology and Paulo Freire's critical pedagogy are also noteworthy historical undercurrents that have shaped Brazil's 2012 National Policy of University Extension. Community is achieved through ongoing interactions based on reciprocity among faculty, staff, students, and the general public; the dialogical method; and the common goal and commitment of prioritizing the needs of socially excluded segments of the population.

The world production of meats is mainly concentrated in the countries with a hot climate. Among these countries, Brazil, considered "world's breadbasket", is located in the intertropical zone, with hot climates and presents lower thermal amplitude. Brazilian poultry is a leader in the production and export of broilers. Brazil has the second largest cattle herd in the world, has the largest commercial herd besides being the largest exporter of beef. Brazilian swine breeding, among the most advanced production chains in the world, occupy the position of fourth largest producer of pork in the world. Projections for Brazil's meat production sector indicate strong growth in the coming years, with countries in hot climates that will continue to sustain future growth in world meat production, ensuring food security in many countries. One of the factors responsible for the success or failure of animal production is the environment, defined by the sum of all physical and biological factors that affect animals. In these regions of hot climates, climatic factors are among the main limiting factors to the development of animal production, which may compromise animal welfare and productivity indices. Behavioral information can aid in the analysis of problems arising from environmental conditions unfavorable to animals, helping both decision making and the use of different environmental conditioning systems. The introduction of technification in the animal behavior evaluation processes, through the use of video cameras and image processing programs, allowed a better interpretation of the behavioral responses, quickly, accurately and non-invasively, gradually being used with greater frequency in the animal production sectors. The study of animal behavior assumes an important role in animal production, since, to rationalize the breeding methods, management, feeding and facilities techniques have been developed that interfere with animal behavior. In this context, the use of digital image analysis techniques, where the animals themselves are used as biosensors in response to environmental conditions, contributes to the analysis of animal behavior, and consequently also to the assessment of the internal environment of the production in hot weather.
