| A suinocultura brasileira é uma atividade importante para o agronegócio do País. Embora o uso de tecnologia nos vários segmentos dessa atividade envolva a substituição do trabalho humano pela automatização de tarefas, o uso da mão de obra humana ainda é significativo. O trabalhador no setor suinícola está exposto a uma série de fatores de risco na execução de suas atividades, dentre os quais a exposição a gases nocivos. O presente trabalho teve por objetivo avaliar a qualidade do ar em instalações de maternidade e creche suinícolas, em duas granjas, com diferentes características (G1 e G2). Para tanto, foram avaliadas concentração de gases (NH3, CO2 e CO) e poeira respirável durante o período de atividades dos trabalhadores. As concentrações dos gases... |

| Brazilian broiler industry adds a significant contribution to country's exports, employing around five million workers in the production chain. The human work involves multiple aspects, including values, beliefs related to work, cultural aspects, personality, motivation etc. The aim of this research was to analyze the associations between broiler accumulated mortality and workers' beliefs related to work, and influences of the supervisors. The study took place in the state of Paraná, Brazil involving 80 broiler integrate farms and 60 workers. A pre-elaborated questionnaire was applied to the workers containing questions related to their health and to some beliefs related to work, as an interview where they could express their feelings. The normal tasks... |

| O resultado da exposição de vacas em produção em ambiente adequado, pode ter reflexo na produtividade leiteira, por permitir o uso correto de equipamentos reduzindo o estresse térmico nos animais, e consequentemente, melhorando a produtividade. No presente trabalho avaliou-se o efeito das temperaturas de bulbo seco e de globo negro, na produção de vacas leiteiras alojadas em sistema de freestall, utilizando-se dois grupos de vacas: mais produtivas, com produção acima de 29 kg/dia e menos produtivas, com produção média abaixo de 14 kgdia-1. Os resultados mostraram os efeitos das variáveis ambientais e do índice de temperatura e umidade regional, no declínio da produção de leite. Não houve correlação significativa entre os valores do índice e o declínio na... |

| ABSTRACT Studies have shown that the benefits from music can improve the welfare conditions of laboratory, pet and production animals. The study aimed to evaluate the influence of music (Antonio Lucio Vivaldi compositions) on behavior aspects (position, activity, stereotypes, social and agonistic behavior) and physiological responses (respiratory rate and rectal temperature) in gestating sows in individual cages (stage 1), and collective stalls (stage 2). 28 animals were studied, 14 belonged to music group, and 14 to the control group (without music).The respiratory rate had the lowest averages in the group with music, for example, in stage 1, time 1, values of 19.28 and 21.50 mov.min−1. In stage 2, the values found in the same time were 20.36 and 24.16,... |

| Global warming is affecting agribusiness in its economic aspects. Therefore, the prediction of the evolution of Brazilian beef cattle production cost was made using the IPCC forecast scenario for global warming. The methodology consisted of two steps: (i) the development of a fuzzy model that estimated the grazing land capacity (RP) decrease risk as a function of the changes in the average total rain index, air temperature and increase in extension of the dry season; and (ii) the design of an algorithm for predicting the decrease in production as function of the RPfuzzy model, that results in the impact in beef cattle productivity, and consequent increase in production costs. Historical environmental data from important producing counties in the Cerrado... |

| ABSTRACT The conventional production of eggs in cage systems is intense and compromises the laying hens welfare. More demanding consumer markets have been pushing to abolish the use of cages and thus provide better welfare in poultry laying. This research evaluated the mortality, production, and egg quality of two alternative production systems (free-range and organic free range free-range) and compared them with the conventional system. The research was carried out in two commercial poultry farms and the variables egg weight, shell egg resistance, Haugh unit, mortality and production were recorded during eight months. The results showed that the conventional system presented better production, lower mortality and better shell egg quality. The alternative... |

| ABSTRACT: The objective of this study was to compare the performance of laying hens between automated aviaries, one with and another without acclimatized system. On a daily basis it was registered in each aviary the mortality, the egg production, and the feed consumption. The variables of the dry bulb temperature, relative humidity and black globe temperature were registered every 30 minutes using the thermos hygrometer. Every 28 days ninety eggs from each aviary were collected randomly and the variables egg weight, shell weight, shell thickness and Haugh Unit were registered. The consumption and quality of the electrical energy supply were monitored every 30 minutes using registers of electrical magnitude. The results showed that the acclimatization... |
