Morphometric features of the liver of hens of cross Arbor Icres

The dynamics of morphometric parameters of the liver of broiler chickens of the Arbor Icres cross in postnatal ontogenesis was described. The stud- ies were conducted on the chickens of seven age groups: 1 day, 7 days, 14-, 21-, 28-, 35- and 42- days of age with ten heads in each group. It was revealed that the liver of the chickens consisted of the right, left lateral and left medial lobes. In 37 chickens (52.9 %) left medial and left lateral lobes were separated by tenderloin, and in 33 chickens (47.1 %) this tenderloin was not found. Two chickens (2.86 %) were noticed to have mirror arrangement of the lobes of the liver. It was probably abnormal development and did not affect functional state of the liver. The absolute mass of the liver of chickens from 1 day allowance to 42 days of age increased from 1.19 ± 0.04 to 50.44 ± 3.14 (P
