Background: The proventriculus, component of digestive system of bird secretes hydrochloric acid and pepsinogen which helps the churning of food material that takes place in ventriculus. Pepsinogen produces pepsin and it smashes the peptide bonds of amino acid of food material. Methods: The twelve proventriculus samples of Guinea fowl birds were fixed in 10% neutral buffered formalin and Bouin’s fluid for histological procedure while chilled acetone and chilled ethanol were used as the fixatives for histochemical studies. The fresh unfixed samples were used on cryostat for studies of succinic dehydrogenase enzyme.Result: Histomorphologically the proventriculus of Guinea fowl was observed as the typical tubular component with four tunics from inside to outside as tunica mucosa, tunica sub mucosa, tunica muscularis and tunica serosa. The submucosal layer comprised with proventricular submucosal gland (PVSMG) which was encapsulated by elastic fibers. Tunica muscularis was inner longitudinal and outer circular layer, while the tunica serosa was observed with surrounding adipose tissue as the connective tissue constituent to endow the access of nutritional supply in the form of blood vessels. The luminal surface of proventricular submucosal glands has shown the significant activity of glycogen while intercalated, intralobular and interlobular ducts have exhibited the weak activity towards the same. The glandular cell rod of PVSMG, serosal layer and adjoining connective tissue with blood vessels has exhibited very weak activity of alkaline phosphatase. Mucosal folds and lumen of PVSMG has shown the weak activity of acidic phosphatase but the serosal limiting membrane has shown very weak activity. The succinic dehydrogenase activity was seen in the connective tissue septa of submucosal glandular cellular rods and the intense activity was observed at tunica muscularis.

See-see partridge (Ammoperdix griseogularis) and pheasant (Phasianus colchicus) belong to Galliformes and the family Phasianidae. These species are nearly similar in appearance specifications to other Galliformes birds in terms of physical and physiological characteristics. However, the size of the pheasant's body is much larger than that of the see-see partridge. Although both birds are in the same order, pheasants live more in the forest, whereas see-see partridge make their home in the desert and semi-arid areas (König et al., 2016;

“…Its specialty is to grind the ingested food material. The muscular thick wall of gizzard holds diminutive crystals which aids as the mechanical crushing component for food material to be digested by birds (Saran et al 2019). The functional stricture of the gizzard is analogous to the teeth in other animals (Fritz et al 2011).…”

Background: The gizzard is a muscular stomach of the Gastrointestinal tract of bird that holds sparing crystals which aids as the mechanical multure component for food material to be ingested by birds. Its specialty is to grinding of ingested food material after secretion of HCL (Hydrochloric Acid) and pepsinogen enzymes in the proventriculus. Methods: The twelve samples of gizzard of guinea fowl were fixed in 10% NBF (Neutral buffered formalin) and Bouin’s fluid for histological while chilled acetone and chilled ethanol for histochemical studies. The fresh unfixed tissues were used for the cryostat section for the demonstration of different enzymes.Result: The tubular glands were main feature of mucosal layer but sometime acinar glands also found as the replacement of tubular glands with lymphoid aggregation. The horizontal koilin was also noticed between long mucosal folds. Tunica submucosa was discovered in squeezed manner in comparison to the mucosa. The tunica muscularis has shown inner circular and outer longitudinal as the thick layer. It was intermingling with collagen and elastic fibers. Histochemically the gizzard was examined for glycogen, alkaline phosphatase, acid phosphatase and succinic dehydrogenase.
