O Brasil apresenta grande potencialidade na produção de carne de frango e é um grande destaque internacional nas exportações dessa proteína. Dentro da agropecuária nacional é classificada como uma das atividades mais bem consolidadas, devido a precariedade de informações sobre comercialização e consumo local da carne de frango o presente estudo apresenta como objetivo a caracterização do consumo e do consumidor na cidade de Salgueiro no estado do Pernambuco. A pesquisa ocorreu no município de Salgueiro-PE, foi usado o método de pesquisa “survey” para coleta das informações da pesquisa com a resolução de questionário, o questionário era composto de perguntas abertas e fechadas e os entrevistados foram selecionados aleatoriamente no estabelecimento de compra. Foram aplicados 364 questionários no período de 19 a 25 de agosto de 2019. Após a coleta de dados, os mesmos foram destinados e convertidos em planilha do programa Excel, que depois de ordenados mediante as construções matemáticas e comparativas, os resultados ficaram apresentados na forma de tabelas e gráficos. Posteriormente, na segunda etapa, os dados foram submetidos aos testes de correlação sendo descritos em gráficos com o software estatístico R Core Team (2022), para a determinação da relação entre dependência de variáveis. A presente pesquisa demonstra uma maior porcentagem dos entrevistados de mulheres (60,40%), sendo que do público entrevistado 26,11% tinham idade de 20 a 25 anos, do total de entrevistados 97,8% afirmam que consomem carne de frango, os que não se alimentam dessa proteína afirmam que o motivo é pelo fato de acreditar no uso de hormônios na dieta dos frangos ou simplesmente por não apreciarem essa carne, 48,9% consomem a proteína do frango diariamente, peito e coxa são os cortes mais consumidos pela comunidade local apresentado para ambos um percentual de consumo igual a 26,7% dos entrevistados. Pode-se concluir que o município de Salgueiro-PE possui potencialidades para o mercado de carne de frango comercial, uma vez que seu consumo demonstrou ser bastante expressivo.

The management of the thermal environment to which dogs are exposed should be included in strategies to improve their welfare. An online questionnaire was administered to 624 owners of Siberian Husky dogs residing in Brazil, with the objective of assessing their perceptions regarding their dogs’ capacity to adapt to heat, and its association with the owners’ routine care. Owners who believed that dogs are low-heat-tolerant animals were more likely to report heat response behaviors from their dogs. Overall, owners reported walk with their dogs during early morning, late afternoon and nighttime. They also reported solar radiation as the primary criteria for determining the time to walk with their dogs. However, owners who reported walking with their dogs at noon mentioned time availability as their primary criteria. In conclusion, owners perceive Siberian Husky dogs living in Brazil as being poorly adapted to heat, and this perception appeared to influence their positive attitudes towards protecting their dogs from heat stress by choosing to walk them during times with less solar exposure. However, the lack of time for owners to walk with their dogs during cooler periods can still be a risk factor in exposing the animals to extreme hot conditions.

This study aimed to evaluate the effects of phytase enzyme supplementation on the thermoregulatory responses of Japanese quails (Coturnix japonica) exposed to different thermal environments. A total of 720 one-day-old laying quails were assigned to a completely randomized design with five dietary treatments (0, 500, 1000, 1500, and 3000 FTU of phytase) and three thermal conditions: thermal comfort (24 °C) and heat stress environments (30 °C and 36 °C). Each treatment had six replicates with eight quails per experimental unit. Data were collected during the early laying phase, peak egg production, and the final laying phase. Measurements included rectal and surface temperatures (assessed via thermographic imaging), allowing the calculation of core-to-surface and surface-to-environment thermal gradients. Quails exposed to severe heat stress (36 °C) showed increased heat dissipation via convection (p = 0.001) and radiation (p = 0.029) when supplemented with phytase doses above 1500 FTU/kg. Additionally, high-dose phytase supplementation reduced the cloacal temperature and optimized thermal gradients, indicating a potential protective effect of exogenous phytase in alleviating heat stress. Overall, these findings highlight phytase supplementation as a promising nutritional strategy to enhance heat tolerance, mitigate thermal stress, and improve the welfare and physiological resilience of quails throughout the production cycle.

A cross-sectional study was carried out on small-scale dairy farms in Paraíba State, Brazil, to evaluate the prevalence and anatomical distribution of integument injuries in grazing dairy cows. Twelve herds (n = 12) were assessed, recording herd size, milk yield, and daily hours of pasture access. The integument of five body regions (back/shoulder/neck, carpus, flank/side/udder, tarsus, and hindquarters) was scored for hairless spots, lesions, and swellings (0 = absent; 1 = present). Among 335 cows observed, 267 (81.5%) presented at least one injury. The most frequent conditions were hairless patches on the hock (65.4 ± 5.03%), lesions on the flank/side/udder (34.5 ± 1.46%), and swelling in the back/shoulder/neck region (52.9 ± 5.86%). Cluster analysis revealed distinct patterns of integument injuries among cows. The high prevalence of integument injuries indicates that even in grazing systems, welfare concerns persist. Neck swelling and hairless spots on the hock were the most common problems, emphasizing the need for improved management and environmental practices to enhance welfare outcomes. These findings have practical implications for welfare assessment and management strategies in tropical grazing dairy systems.
