Broiler growth rate contributes to behavioral differences and sheds light on the impact on welfare
Credit: Pixabay/CC0 Public Domain Poultry companies weigh costs and efficiency on higher animal welfare standards, a study comparing traditional, growing broiler varieties has shown that slow-growing chickens exhibit behaviors more closely related to positive welfare. Chickens, specially raised for meat production, are usually grown for 6-8 weeks, but must grow up for up to 12 weeks to mature. Though popular…

Capturing finer-scale topographic differences improves the ability of Earth system models to reproduce observations
Spatial pattern of number of topographic units (TGU) per 0.5 degree grid. We demonstrate the ability of a terrain-based subgrid structure to capture terrain heterogeneity across a mountainous region and associated data that is a measure of the computational efficiency of the data reduction metric (DRM). We define a variable number of TGUs per grid in conjunction with the allocation…
