Histological and histomorphometric study of the cranial digestive tract of ostriches (Struthio camelus) with advancing age

The present study was conducted to determine the histological and histomorphometric variations in tongue, oesophagus, proventriculus, gizzard of ostriches (Struthio camelus) with regards sex advancing age. A total 40 healthy both sexes five age groups; young (up 1 year, 2 years 3 years) adult (3 4 above equal numbers (n = 8) were used this study. organs under collected immediately after slaughtering birds. Overall, colour, shape, weight various dimensions (length, width, diameter) recorded. mean values gross anatomical variables studied increased (P < 0.05) among all groups (i.e., from years, years). Similarly, (birds aged grew as well.
