Background: Fowl adenoviruses (FAdVs) are distributed widely throughout the world, and domestic avian species of all ages are susceptible. Fowl aviadenoviruses (FAdVs) can be separated into 5 different species (A-E) with various genotypes and 12 serotypes. Some geno- or serotypes induce hepatitis-hydropericardium syndrome (HPS), inclusion body hepatitis (IBH), and adenoviral gizzard erosion (AG...

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...

wk. Feed consumption, body weight and feed conversion were measured at 2, 4 and 6 wk. Carcass yield and weights of abdominal fat, gizzard and ceca were also determined at 6 wk. All birds were intramuscularly immunized with killed vaccine of Newcastle and Avian Influenza (H9 N2) at 8 d and antibody titer responses to Newcastle and Influenza were determined by hemagglutination inhibition (HI) tes...

The purpose of this study was to present the structure of nematofauna community with particular emphasis on stomach (proventriculus and gizzard) nematodes in wild ducks wintering in large numbers in the North-Western Poland. Hosts (n=152) were represented by 17 species from eight genera belonging to three different ecological tribes: Anatini, Aythyini, and Mergini. Parasitic nematodes (n=14,396...

cDNA clones for chicken B-CK were isolated by immunoscreening from a gizzard cDNA library constructed in the expression vector lambda gtll. The entire coding portion in addition to the complete 3' untranslated region and 42 bp of the 5' noncoding part are represented in the clone H4. On RNA blots H4 insert DNA hybridized to a 1600 bp poly(A)+ RNA from gizzard, brain and heart but not to breast ...

The microstructure of oesophagus and stomach in grey-backed shrike were examined by means of light microscopy. The results showed that the oesophagus glands were mucous glands, the shedding glandular cells and the mucin from the oesophagus glands secreted to the lumen. The number of the glands in the thoracic part was less than that of in the cervical part. The lumens of the glands showed an in...

ABSTRACT The supply of salt water in the semiarid region is a recurrent practice, as there severe shortage for use animal consumption. Thus, most times offered to birds can contain salts above recommended amount. present study aimed evaluate production performance and morphometry organs Japanese quails they were supplied with drinking different concentrations sodium chloride, while being mainta...
