Anatomical, Morphological and Histological Studies of Infundibulum of Indigenous, Sonali and Rhode Island Red (RIR) Chickens (Gallus gallus domesticus L.) in Bangladesh

The present study was carried out to throw light on the anatomical, morphological and histological changes of oviductal infundibulum pre-laying, laying regressing reproductive stages chicken (Gallus gallus domesticus L.) from indigenous (6-10 months), sonali (3-19 months) rhode island red (RIR) (4-18 breeds. Anatomically, pre-laying chicks each breed not well differentiated into funnel neck parts, but in hens it subdivided two regions. parameters i.e. length, breadth weight were determined. mean length at three breeds statistically significant (F2,6=9.35, p<0.05; F2,6=7.62, F2,6=41.93, p<0.01), showed insignificant values (F2,6=2.56, p>0.05; F2,6=3.36, p>0.05) whereas significantly different (F2,6=5.60; p<0.05). (F2,6=0.89, F2,6=1.25, they difference stage (F2,6=7.81, For study, paraffin sections (5-6 μm) prepared stained with hematoxylin eosin layers recognized under microscope. features varied regards mucosal folding, sub-mucosa, mascularis serosa all anatomy, morphology histology revealed that differences among resulted breeds’ variety for cellular by accumulation secretory materials egg production.
