The article provides microscopic indexes of the growth of oviduct of hens of the cross Hisex with the age of 1, 30, 60, 90, 120 days. We established two periods of varing of morphometric parameters: moderate augmentation and incense augmentation.The thickness of walls of oviduct is the most intensively increased in hens with the age from 90 to 120 days (for 165 % in cranial, for 420 % middle, for 501 % in caudal parts). The indexes of height of plica of mucosae, thickness of mucosae and muscle is also most intensively grown in hens of 90-120-day age. Between age of hens and microscopic indexes there is a polinomialy dependence. The hens of all age groups the thickness of walls of oviduct and its muscles is the biggest in caudal part (70.24±6.28 - 1430.22±173.52 and 39.72±3.26 - 1307.57±188.12 mcm), and thickness of mucosae and height of plica in the middle part (37.45±5.28 - 310.72±36.37 and 39.95±2.54 - 82.78±10.12 - 2799.29±304.54 mcm) of the organ. The parameters of morfometer of oviduct in clinically healthy birds shall be used as parameters of norm when diagnosing diseases of various origins and in experimental studiest.
