title: Plasticity of Digestive System of Waders (Charadrii) as Migrants (Peculiarities of Fat Accumulation and the Source of Essential Polyunsaturated Fatty Acids During Migratory Stops in the Azov-Black Sea Region)
abstract: Abstract The plasticity of the digestive system (DS) of birds allows them to use a wide range of feeds, which is especially important for migratory birds. Some fatty acids (FAs) included in the spectrum of polyunsaturated FAs (PUFAs) are not synthesized in the bird organism, and are supplied only with food. They determine the level of unsaturation of lipids, and are essential for the organism. Among other important functions of these FAs are energy: they affect the energy metabolism of muscle ce
