—We examined diet patterns of omnivorous gizzard shad Dorosoma cepedianum in Acton Lake, Ohio, during 1994–1997 using a multiple stable isotope analysis to quantify the role of this species in the system. On most dates, zooplankton were relatively depleted in d13C (about 230‰ to 225.5‰) compared with sediments (225‰), permitting construction of a mixing model to determine the proportion of C de...

AIM This study aimed to detect Salmonella species found as contaminants in chicken carcass (thigh, breast, wings, liver, and gizzard). MATERIALS AND METHODS A total of 75 chicken samples including thigh, breast, wings, liver, and gizzard (15 of each) were collected from different markets in Sohag city for detection of Salmonella species by culture methods, biochemical tests, serology, and pol...

There is little consensus as to the capability of poultry to utilize dietary phytate without supplemental phytase. Therefore, an experiment was conducted to examine the extent to which endogenous phytase of intestinal and cereal origin contributes to phytate degradation in birds aged 0 to 14 d posthatch. Ross 308 broilers (n = 720) were fed one of 4 experimental diets with differing dietary ing...

Injection of chicken gizzard actin into BALB/c mice resulted in the isolation of a smooth muscle-specific monoclonal antibody designated CGA7. When assayed on methanol-Carnoy's fixed, paraffin-embedded tissue, it bound to smooth muscle cells and myoepithelial cells, but failed to decorate striated muscle, endothelium, connective tissue, epithelium, or nerve. CGA7 recognized microfilament bundle...

A young Fisher's lovebird (Agapornis fischeri), showed clinical symptoms with general weakness, diarrhea, ruffled feathers and unilateral extrarhinoectasia and died finally. Gross necropsy revealed marked edema, congestion and hemorrhage on the distal part of the gizzard and proximal part of the duodenum. On microscopic examination, a large number of oval budding yeast-like fungi were observed ...

Impaction of the gizzard was diagnosed in 33 1-to-4-wk-old lesser rhea (Pterocnemia pennata) raised on farms in Patagonia, Argentina. The birds showed anorexia, lethargy, constipation, dehydration, weight loss, and weakness. Necropsy revealed gizzard impaction by fibrous material, sand, rocks, and rubbish. Also, excess fibrous material was observed in the small intestine, and intussusception wa...

The present study was performed for investigation on possible effects of exogenous ghrelin (GH-releasing peptide) on liver, heart, gizzard (proventriculus+gizzard), intestine and breast muscle weights. One hundred fertilized eggs were divided into two groups includes control or group1 (without any in ovo ghrelin administration) and group2 (in ovo administration of 100ng/egg ghrelin at day-5). I...

To explore the suggestion that alpha-actinin cross-links actin filaments to the microvillar membrane (Mooseker and Tilney, 1975, J. Cell Biol. 67:725--743; Mooseker, 1976, J. Cell Biol. 71-417--433), we have assessed the possible relatedness of alpha-actinin and the brush-border 95-kdalton protein by four independent criteria: antigenicity, mobility on SDS gels, extractability in nonionic deter...
