Determination of Anatomical morphology in turkey spp.(Meleagris gallopavo) for post mortem diagnosis with histomorphological characteristics of liver

Abstract

The study was aimed to investigate the anatomical (body weight, proventriculus, proventriculus-gizzard junction, liver and cecum) and histological (liver) features of the turkey to identify the gross and hismorphological characteristics for post mortem diagnosis of disease. The study was carried out in 20 turkeys and categorized them on the basis of their age and sex. The average body weights of male and female were found 3.55± 0.034 kg and 2.75±0.05 kg. In male, the average length, width and diameter of proventriculus were 5.16±0.033 cm, 2.13±0.044 cm , 3.59±0.027 cm , average length, width and diameter of proventriculus-gizzard junction were 1.81±0.036 cm ,0.87±0.036 cm and 2.32±0.041 cm and length, width and diameter of cecum were 22.81±0.204 cm ,1.13±0.042 cm and 3.9±0.039 cm where in female the average length, width and diameter of proventriculus were 2.76±0.043 cm , 1.87±0.422 cm , 3.25±0.045 cm , average length, width and diameter of proventriculus-gizzard junction were 1.22±0.055 cm, 0.91±0.052 cm and 3.23 ±0.051 cm and length, width and diameter of cecum were 21.24±0.047cm, 1.17±0.042 cm and 3.14±0.052 cm. The internal surface of proventriculus was found reddish in color. The membrane of pair ceca was found greenish and membrane wall was found thick to thin according to the segments of ceca. The gross feature of liver in turkey was dark brown in color and the average weight of the liver in male was 50.66±0.030 gm while in female was 59.37 ±0.102 gm. Histological features revealed that liver of turkey were consists of parenchyma and stroma under microscope. Hepatocyte, central vein, hepatic sinusoids and portal triad are the main histological features of turkey liver. These prominent anatomical and histological features of several internal organs of turkey will be effective for post mortem diagnosis and treatment of turkey and it will helps to differentiate in diagnosis among contagious diseases of turkey.
