DOI: 10.1002/jav.03446
Abstract: Feather structure contributes greatly to a birds' ability to repel water, which is essential for thermoregulation and energy use. Water repellency of feathers has traditionally been inferred by measuring a structural index based on the… read more here.

DOI: 10.1007/s12649-020-01138-7
Abstract: Feather is a good source of nitrogen but the highly rigid structure limits its utilization and leads to environmental pollution and resource wastage. Traditional feather degradation processes such as alkali hydrolysis and steam pressure cooking… read more here.

DOI: 10.1098/rsos.220488
Abstract: Oil pollution has profound negative impacts on the marine environment, with seabirds particularly vulnerable to oiling, due to the amount of time spent on the sea surface foraging or resting. Exposure to oil can affect… read more here.

DOI: 10.1186/s12934-025-02878-8
Abstract: Feather waste, a byproduct of the poultry industry, remains underutilized due to its recalcitrant nature. While microbial conversion holds substantial potential, the scarcity of high-efficiency degrading strains hampers industrial application. A novel feather-degrading actinobacterium, designated… read more here.

DOI: 10.1371/journal.pbio.3000132
Abstract: Feathers are arranged in a precise pattern in avian skin. They first arise during development in a row along the dorsal midline, with rows of new feather buds added sequentially in a spreading wave. We… read more here.

DOI: 10.3389/fvets.2019.00230
Abstract: Repetitive pecking at the feather cover of other birds (FP) is one of the most important welfare problems in domestic birds. It is not only characterized by motor symptoms, but also by an innate vulnerability… read more here.
