“…It is now widely accepted that climate change is happening, and that it represents one of the greatest threats faced by our planet, its populations and economies (Skuce et al, 2013). According to the United Nations Intergovernmental Panel on Climate Change (IPCC), average global temperatures will increase between 1.8°C and 4.0°C in the next 90 years (Yatoo et al, 2012).…”

Abstract. The objective of the present study was to investigate whether climate change in recent years have influenced the onset of acute outbreaks of Fasciola hepatica in ovine farms in southern Italy. In May-June 2014, a severe outbreak of F. hepatica occurred in three sheep farms in the Campania region. Clinical, coprological and necroscopic examinations were performed. Morbidity and mortality due to F. hepatica were 3-67% and 3-50%, respectively. Coprological examinations showed high values of F. hepatica eggs per gram (EPG) of faeces (860-1,240). Similarly, high adult parasitic burdens were found in animals that had sucombed (124-426 flukes). The study area was georeferenced and climatic data (temperature, humidity, days of rain and total amount of rainfall) were recorded at four georeferenced meterological stations in the study area. Montly data were processed and analyzed for the period 2000-2013 to evaluate the change of the climatic parameters during these years. The results show that there was a significant increase (P <0.001) of temperature, increased rainfall and increase in the number of rainy days compared to previous years. In addition to the outbreak reported here, we discuss the potential effects of climate change on the epidemiology of F. hepatica and the implications for sheep farming in the Mediterranean area.

“…The rise in global temperature is also expected to affect livestock health in temperate regions (Skuce et al, 2013). In fact, a greater incidence of sanitary problems has already been observed in hot months than in cold months in temperate regions in association with better conditions (warmer temperatures) for pathogen proliferation (Skuce et al, 2013).…”

Physiological responses of growing pigs to high ambient temperature and/or inflammatory challenges

et al. 2017

-Global warming is one of the major environmental threats facing the world in the 21st century. This fact will have a significant impact on pig production due to its direct effects on welfare, health, and performance of pigs. Besides, the effects of high temperatures will presumably become more important over the next decades due to the development of pig production in developing countries mainly located in tropical and subtropical areas, where animals are often exposed to ambient temperatures above their thermal comfort zone. Furthermore, pigs reared in tropical areas are often confronted to sanitary challenges including poor hygiene conditions, lack of respect for sanitary rules, and pathogens. This results in the stimulation of the immune system and, as a consequence, in the production of pro-inflammatory cytokines and neuroendocrine adjustments that, in turn, usually have a negative impact on growth and feed efficiency. Although the effects of high ambient temperature and disease on pig physiology and performance have been well documented in literature, little is known about the associated effects of both factors. This understanding may contribute to a better quantification and comprehension of the physiological and metabolic disturbances occurring in practical conditions of pig production in tropical areas and, more generally, in many other geographic areas that will be influenced by the perspective of global warming. Therefore, the objective of this work is to provide an overview of recent research advances on the physiological responses of growing pigs during acclimation to high ambient temperature and on the potential effects of high ambient temperature on the ability of growing pigs to resist, cope with, or recover from an inflammatory challenge.

“…Climate change is expected to result in more frequent, more intense, and longer heat waves (HENDERSON et al, 2011;RENAUDEAU et al, 2012;SKUCE et al, 2013;SOSSIDOU et al, 2014). The heat wave can be defined by long, hot summers with higher minimum temperatures and humidity (KENT et al, 2014).…”

Global warming increases the occurrence of events such as extreme heat waves. Research on thermal and air conditions affecting broiler-rearing environment are important to evaluate the animal welfare under extreme heat aiming mitiga tion measures. This study aimed at evaluating the effect of a simulated heat wave, in a climatic chamber, on the thermal and air environment of 42-day-old broilers. One hundred and sixty broilers were housed and reared for 42 days in a climatic chamber; the animals were divided into eight pens. Heat wave simulation was performed on the 42 nd day, the period of great impact and data sampling. The analyzed variables were room and litter temperatures, relative humidity, concentrations of oxygen, carbon monoxide and ammonia at each pen. These variables were assessed each two hours, starting at 8 am, simulating a day heating up to 4 pm, when it is reached the maximum temperature. By the results, we concluded that increasing room temperatures promoted a proportional raise in litter temperatures, contributing to ammonia volatilization. In addition, oxygen concentrations decreased with increasing temperatures; and the carbon monoxide was only observed at temperatures above 27.0 °C, relative humidity higher than 88.4% and litter temperatures superior to 30.3 °C.KEYWORDS: ammonia, gas production, animal welfare, oxygen, litter temperature ONDA DE CALOR SIMULADA E SEU IMPACTO NO AMBIENTE TÉRMICO E AÉREO DE FRANGOS DE CORTE RESUMO:O aquecimento global aumenta a ocorrência de eventos extremos como as ondas de calor. Pesquisas sobre como as condições térmicas e aéreas afetam o ambiente de produção de frangos de corte são importantes para se avaliar o bem-estar animal sob condições extremas de calor, objetivando medidas mitigadoras. Este estudo pretende avaliar o efeito da simulação de ondas de calor em câmara climática, sobre o ambiente térmico e aéreo de frangos de corte com 42 dias de idade. 160 frangos foram alojados e criados, de 1 a 42 dias de idade, em câmara climática que foi dividida em oito baias. A simulação de onda de calor foi realizada no 42º dia de criação das aves, memento de maior impacto e da coleta dos dados. As variáveis foram coletadas em intervalos de duas horas a partir das 8 horas da manhã, simulando o aquecimento do dia até às 16 horas, horário de máxima, sendo coletados temperatura ambiente, temperatura da cama, umidade relativa do ar, concentrações de oxigênio, monóxido de carbono e amônia em cada baia, nos intervalos de duas em duas horas. Com os resultados obtidos na câmara climática, foi possível concluir que o aumento da temperatura ambiente ocasionou aumento na temperatura da cama, o que, consequentemente, contribuiu para o aumento da volatilização da amônia. A concentração de oxigênio foi reduzida enquanto a temperatura foi aumentada. A presença de monóxido de carbono foi observada quando a temperatura ambiente estava acima de 27,0 ºC, a umidade relativa superior a 88,4% e a temperatura da cama estava superior a 30,3 ºC.
