In case of proventriculus
and gizzard, the lesion values for 400 and 500 AF fed group showed significantly (P [less than or equal to] 0.
contents were obtained by dissection, acidified with 10% HC1, centrifuged, and the stomach contents pellet was kept, and the acid was discarded.
Separation into three groups was necessary because previous studies conducted on waterfowl indicated that contents can differ between proventriculus
and esophagus (Bartonek and Hickey, 1969; Sedinger, 1986), and between esophagus and gizzard (Swanson and Bartonek, 1970; Briggs et al.
The values we obtained for GPT agree with Lee and Lawrence (1997), who reported that the penaeid proventriculus
can be filled after 1-10 min of eating, and that foregut clearance can be 75% complete within 1 h.
0 [micro]L/mL effluent exhibited a pale blue staining in salivary gland, proventriculus
, brain ganglia, and midgut tissues (data not shown).
Arthropodan appendages were present in the gut of two dismembered specimens, and a tri-lobed proventriculus
In the absence of a crop, the esophagus communicates directly with the spherical proventriculus
, which in turn opens into the midgut.
Weights of the small intestine, proventriculus
and gizzard with content, liver, pancreas, spleen and bursa of Fabricius were recorded.
Whole-body radiographs taken with the bird under anesthesia (anesthetic protocol as described previously) revealed a severely dilated, gas-filled proventriculus
, ventriculus, and intestines orad to a tubular soft-tissue opacity in the ileo-ceco-rectal area (Figs 1 and 2).
Real-time reverse transcription PCR (rRT-PCR) was used to detect ABV RNA from cloacal swab and crop biopsy specimens from live birds and from brain or proventriculus
samples from dead birds (3).
ends in a constriction as it joins the midgut.
This bias can be avoided by examining only the contents of the esophagus and proventriculus
(Swanson and Bartonek 1970, Reinecke and Owen 1980, Rundle 1982).
