Morphological Development of the Gastrointestinal Tract Of Helmeted Guinea Fowl (Numida meleagris) at Pre-Hatch and Post-Hatch
This study was conducted to investigate the morphological development of the Helmeted Guinea fowl (Numida meleagris) gastrointestinal tract preand post-hatch. Eighty seven (87) eggs were purchased from the Poultry unit of National Veterinary Research Institute (NVRI), out of which eighty one (81) were used for pre-hatch and six (6) were allowed to hatch for post hatch studies. The development w...
متن کاملStudies on the Histochemistry of the Proventriculus and Gizzard of Post-Hatch Guinea Fowl (Numida meleagris)
The proventricular surface epithelial cells were positive for both acid and neutral mucins and stained intensive for acid phosphatase and adenosine triphosphatase. The proprial gland cells revealed histochemical distribution and activity of various enzymes and lipids similar to that of the submucosal gland cells. However, the ductular cells of the submucosal glands showed comparatively stronger...
متن کاملHistomorphology of Thymus Gland in Guinea Fowl (Numida meleagris)
The thymus gland is a lymphoid tissue derived from III and IV pharyngeal pouches. It is the source of stem cells that migrate to other lymphoid organs and participate in immune reactions (Kent, 1978). The thymus gland is regarded immunologically as a primary or central lymphoid organ and its presence is essential for the development of peripheral lymphoid tissues and their associated adaptive i...
متن کاملHistogenesis of the Oesophagus of Guinea Fowl (Numida meleagris) at Prehatch and Posthatch
The histogenesis of the primordial oesophagus was studied to determine the period in which the tunics of the oesophagus developed and became functional in the helmeted guinea fowl (Numida meleagris). Eighteen embryos and nine keets were studied at prehatch and posthatch, respectively. Simple columnar epithelium surrounded by mesenchymal cells was obvious at the 8th day of embryonic development....
متن کاملThe cost of running uphill: linking organismal and muscle energy use in guinea fowl (Numida meleagris).
Uphill running requires more energy than level running at the same speed, largely due to the additional mechanical work of elevating the body weight. We explored the distribution of energy use among the leg muscles of guinea fowl running on the level and uphill using both organismal energy expenditure (oxygen consumption) and muscle blood flow measurements. We tested each bird under four condit...
