Outline
To clarify the impacts of climate change on animal productivity, feeding experiments using lactating cows, layer chickens, and finishing pigs will be performed in a temperature- and humidity-controlled room, and their productivity will be evaluated. After conducting a regression analysis of the data, images of the spatial distribution of their productivity will be generated using the Agro-Meteorological Grid Square Data system (NARO) according to the original climate and economic scenarios established in this project. Data on the environmental impact on the productivity of growing heifers, broilers, and growing pigs are also available. These data will be downscaled from a 10 km grid square to 1 km grid square. Based on the ease of introduction to farmers, the candidate for adaptation technology in animal production for hot environments will be selected, and evaluated. Our project will contribute to the projection of climate change impacts on animal production and produce scientific knowledge of adaptation technology for hot environments.
Goals
- Generate images of the spatial distribution of the impacts on the productivity of lactating cows, laying chickens, and finishing pigs under climate change.
- Upgrade existing data for growing heifers, broilers, and growing pigs to 1 km grid square and evaluate.
- Evaluate the candidates of adaptation technology for animal production under a hot environment.
Target items
- The effect of environmental temperature and humidity on feed intake and milk production on lactating cows will be clarified.
- The effect of environmental temperature and humidity on egg scores and egg quality on laying hens will be clarified.
- The effect of environmental temperature and humidity on feed intake and body weight on finishing pigs will be clarified.
Adaptation options
- Thermal barrier coating to the barn roof
