The effects of natural bioadditive on the morphofunctional development of the digestive organs in quails
The beneficial effects of a bioadditive (containing hydroponic wheat and watery extract of astragalus) in the diet of Texas quails (Coturnix coturnix) on the development of the digestive organs (gizzard, proventriculus, liver) were studied on two treatments (control and bioadditive-fed, 60 birds per treatment) of quails using light microscopy and morphometry of the histological samples. Certain common patterns were determined in the development of morphofunctional structures within the organs; the better development of these structures was found in the bioadditive-fed treatment. The conclusion was made that this bioadditive enhances growth and productive performance in quails.
