• Abstract

  Most of the 220 million Brazilian beef cattle herd are managed in pasture or feedlots, where they are exposed to air temperature above 30°C and solar radiation above 800 W m-2. These conditions cause heat stress in cattle, especially for European breeds and their crossings. One alternative to reduce heat stress is to provide artificial shades for animals, which has been shown by previous …

  Shading with photovoltaic panels to beef cattle: a study on thermal equilibrium, on the economic viability and environmental impact, AP.PFPMCG.R

• Abstract

  Skin surface evaporation (ES) accounts for about 80% of the thermal energy losses by cattle in hot environments. However, the relative efficiency of the several methods used to determine ES is not clearly established. Direct evaluation of water losses through the body weight differential within a given time interval can be considered as the most confident technique, but it requires costly…

• Effect of shading on the physiological and behavioral responses of beef cattle, BP.TT

• Abstract

  Our goal is to study the impact of artificial shades from photovoltaic panels on thermal comfort, animal welfare and performance of crossbreed sheep Dorper x Santa Inês. In addition, electric power generation, economic viability and environmental benefits of installing photovoltaic panels will be measured. This study will be conducted between August and November, 2021, in the experimental…

• Abstract

  The expected increase in the world population to 9.7 billion by 2050 and simultaneous overall demand for agricultural products is expected to grow at 1.1 percent per year until 2050, while meat consumption is expected to grow at 0.75 percent per year. In this frame, call for an increase in food production will be on scenario global warming in which temperature dramatic increase could exce…

  Precision livestock farming (PLF) to investigate of the environmental impact on growth performance of feedlot cattle, BE.PQ

• Abstract

  The research team in the Wildlife Conservation Physiology section of the Brain Function Research Group at the University of Witwatersrand, South Africa, has developed many methods to evaluate physiological and behavioral responses of wild free-ranging species. Undoubtedly, the challenges of assessment of physiological responses in free-ranging wild species is much greater when compared wi…

  Thermal physiological responses of animals: challenges to obtain these measures in field, BE.EP.PD

• Abstract

  Agricultural production systems are of different ways integrated. One of the universal factors for all countries is the question of the influence of environmental variables on production. Among these factors is the temperature, this is being widely studied due to growing discussion about global or local warming. Heat stress causes a series of physiological changes, but these need to be be…
