Recent research has consistently related the production and consumption of meat with environmental degradation, health problems, and damage to animal welfare. However, meat consumption represents a well-established eating behavior among many consumers. After all, meat is a central food in many cultures, and changing eating habits can be very challenging. Nevertheless, there is a group of consumers who have reduced the consumption of meat in their diet. Understanding the facilitators and barriers that influence these behavioral changes in different cultures and contexts can help to promote future collective reductions in meat consumption. This article investigates the main facilitators of and barriers to the reduction of consumption in the largest meat-consuming market in the world to contribute to the advancement of knowledge on meat-reduced diets. In order to achieve this objective, semi-structured interviews were conducted with consumers who reduced their meat consumption. In this context, a content analysis was conducted to identify 22 facilitators and 15 barriers classified according to the COM-B system. This system conceptualizes Behavior, which can be influenced by Capability, Opportunity, and Motivation. The results of this research corroborate previous discoveries or confirm the presence of a set of facilitators of and barriers to the reduction of meat consumption previously suggested in the literature.

In this direction, it is important to learn from experience and reduce the missteps witnessed in terrestrial animal farming. In this Research Topic we endeavor to channel scientific expertise to improve the lives of aquatic animals reared under farming conditions. Our objective is clear to promote animal welfare science applied to aquatic animal life under farming conditions as an important tool to reach better aquaculture systems. This initiative encompasses farmed animals, while also considering the intricate relationships between humans, animals and the environment. By integrating such considerations, we aim to foster a sense of social responsibility and demonstrate that careful attention to the welfare of farmed aquatic animals' yields benefits for the animals that also cascade through producers, consumers, and other stakeholders.The selection of articles shown here was made to cover key topics involving the improvement of the life quality of farmed aquatic species. Alongside other indicators, stocking densities are a critical point of welfare in aquaculture (1). High stocking densities may cause stress due to lack of space and an increased competition for food, besides a higher risk of injuries and even diseases. On the other hand, very low densities may cause health problems, stress for social species and more aggressive interactions for territorial specieswhile possibly hindering the economic viability of fish farms. In this sense, Saraiva and colleagues brought a d...

Acidification of animal manure has been one of the approaches used to combat the proliferation of bacteria and high volatilization of ammonia (NH3). Conversely, alkalinization is performed with basic oxides in Brazil, which raises the pH of the litter and soil from floors of chicken facility, creating a constant source of contamination in them. In this context, this study was undertaken to examine the effect of sodium bisulfate (SB) and elemental sulfur (ES) on the acidification of different soils from floor of chicken housing facilities, considering their efficiency and reaction time. The experiment involved tree soils collected inside chicken facilities (at six, 36, and 60 months of occupation), as well as soil that was collected outside the facilities, totaling four sampling sites. Both acidifier sources—SB and ES—were applied at six increasing doses (0, 2, 3, 6, 12, and 24 cmolc kg-1 of H+ in the 3-cm soil layer), and incubated for up to 53 days. At the end of each incubation period, the pH of the soil was measured. The results suggest that SB is efficient in reducing the pH of chicken soil, with an immediate reaction occurring after its application. Under the conditions adopted in the present study, the recommended dose of SB to reduce the pH to 5.0 was 6 cmolc kg-1 of H+, which corresponded to the application of 7.2 g of the product in 500 g of soil. Elemental sulfur showed a slow reaction and low efficiency. The use of SB quickly and efficiently provides the acidification of soil from floor of chicken housing facilities.

A acidificação de resíduo de animais vem sendo uma das maneiras de combater proliferação de bactérias e a alta volatilização de amônia (NH3). No Brazil, contrariamente, procede a alcalinização com óxidos básicos com elevação do pH da cama e solo do piso dos aviários, criando neste último uma fonte constante de contaminação. Neste sentido, este estudo teve como objetivo verificar o efeito de Bissulfato de sódio (SB) e enxofre elementar (ES) na acidificação de diferentes solos de aviário, quanto a eficiência e tempo de reação. Utilizou-se três solos coletados dentro de galpões de criação de frango (6, 36 e 60 meses de ocupação), além da coleta do solo externo ao aviário, totalizando quatro locais de amostragens. As duas fontes de acidificantes, o SB e o ES foram aplicadas em 6 doses crescentes (0, 2, 3, 6, 12 e 24 cmolc/kg de H+ na camada de 3 cm de solo), incubados até 53 dias. Ao final de cada período de incubação determinou-se o pH do solo. Os resultados do presente estudo permitiram concluir que o SB é eficiente na redução do pH do solo de aviário com reação imediata após sua aplicação. Nas condições do presente estudo a dose indicada de SB para reduzir o pH para 5,0 foi de 6 cmolc kg-1 H+ que correspondeu a aplicação de 7,2 g do produto em 500 g de solo. O ES elementar mostrou reação lenta e baixa eficiência. Acidificação do solo do aviário pode ser obtido rapidamente e eficientemente com uso de SB.
