“…HS indices can be calculated by weather-related parameters from a meteorological station, by measured data, or by simulated data of indoor parameters [9,30,31]. The investigated relationship between HS indices, which are calculated by the indoor parameters and those calculated by meteorological parameters, show a coefficient of determination above 80% and a slope of the linear regression between 1.17 and 2.13 which means, that the indoor parameters are more sensitive to HS [17]. Nevertheless, the weather-related HS indices can be used as a reliable proxy for the indoor indices.…”

“…The authors emphasized that risks should always be assessed in relation to objectives of analysis. In the case of climate change and confined livestock keeping of pigs and poultry, one of the relevant objectives is related to the evaluation and finally the application of adaptation measures to cope with undesirable weather impacts [17][18][19][20][21].…”

In the last decades farm animals kept in confined and mechanically ventilated livestock buildings are increasingly confronted with heat stress (HS) due to global warming. These adverse conditions cause a depression of animal health and welfare and a reduction of the performance up to an increase of the mortality. To facilitate sound management decisions, livestock farmers need relevant arguments, which quantify the expected economic risk and the corresponding uncertainty. The economic risk was determined for the pig fattening sector based on the probability of HS and the calculated decrease in the gross margin. The model calculation for confined livestock buildings showed, that HS indices calculated by easily available meteorological parameters can be used for assessment quantification of indoor HS, which is so far difficult to determine. These weather-related HS indices can be applied not only for an economic risk assessment but also for a weather-index based insurance for livestock farms. Based on the temporal trend between 1981 and 2017, a simple model was derived to assess the likelihood of HS for 2020 and 2030. Due to global warming, the return period for a 90-percentile HS index is reduced from 10 years in 2020 to 3-4 years in 2030. The economic impact of HS on livestock farms was calculated by the relationship between an HS index based on the temperature-humidity index (THI) and the reduction of the gross margin. From the likelihood of the HS and this economic impact function, the probability of the economic risk could be determined. The reduction of the gross margin for a 10 year return period was determined for 1980 with 0.27 € per year and animal place and increased by the 20-fold to 5.13 € per year and animal place in 2030.

“…The primary heat stress adaptation strategy has been physically modifying the pig's environment (Mayorga et al, 2019;Schauberger et al, 2019). There is an opportunity for breeding heat stress-tolerant pigs (Bloemhof et al, 2008) although there is limited research about different species' and breeds' sensitivity to heat stress and potential trade-offs between sensitivity and productivity.…”

Heat stress is a global issue constraining pig productivity, and it is likely to intensify under future climate change. Technological advances in earth observation have made tools available that enable identification and mapping livestock species that are at risk of exposure to heat stress due to climate change. Here, we present a methodology to map the current and likely future heat stress risk in pigs using R software by combining the effects of temperature and relative humidity. We applied the method to growing-finishing pigs in Uganda. We mapped monthly heat stress risk and quantified the number of pigs exposed to heat stress using 18 global circulation models and projected impacts in the 2050s. Results show that more than 800 000 pigs in Uganda will be affected by heat stress in the future. The results can feed into evidence-based policy, planning and targeted resource allocation in the livestock sector.

Small scale backyard poultry buildings, which could be of any shape and design, are very important and every household in Nigeria should embrace. However, it is difficult for most households to plan and design appropriate buildings for their poultry birds. This study was carried out to design a building which could allow birds to exhibit their natural behaviours without being exposed to hazards and predators. The building with dimensions 2.8 m long, 2.3 m wide and 1.9 m height at the front and 1.3 m at the back was developed using local materials. The building comprised of resting room and a free space for poultry to exhibit their natural behaviours such as dust bathing, wing flapping and preening. There were perches inside the building were birds could roost at night. The indoor and outdoor climatic conditions (air temperature and air relative humidity) were evaluated. The result of the study showed that the highest mean indoor air temperature (30.60 °C) and highest mean indoor air relative humidity (83.88 %) were obtained in the afternoon and night respectively. The lowest mean indoor air temperature (24.23 °C) and mean indoor air relative humidity (66.64 %) were obtained in the night and afternoon respectively. The building was considered affordable ($280.00) and suitable for poultry grown for egg and meat production in the tropical humid climate.
