Morphometric Parameters and the Dynamics of Development of Quail (Coturnixcoturnix) Spleen

IN THE present studyquails Coturnixcoturnix (Linnaeus, 1758) of 3 breeds- Pharaoh, English White quail, Manchurian Goldenwere studied from Azerbaijan from June to September 2018. 120 quails were kept in 3 compartments of a large cage. Materials were referred to in neonatal, juvenile sexual maturity, morphofunctional maturity periods.Up-to the end of researches the spleen grows intensively for 3 months. The decrease of all morphometric indicators of quails’ lifespan was recorded on the 120th day of quails. Comparing the recorded absolute weight of the spleen at 90 days it was decreased from 0.60g to 0.07g in Pharaoh breed, from 0.63g to 0.08g in the English White quails and from 0.57g to 0.06g in the Manchurian Golden quails.
