Emaciation and Sporadic Mortality in Older Laying Hens Caused by Intussusception of the Proventriculus

Avian Diseases, 2018
SUMMARY. Laying hens (n = 2267) ranging in age from 2 to 4 yr in a study evaluating ovarian cancer prevention were necropsied. Those that died or were culled during the 2-yr study (n = 1591) were necropsied weekly to determine the most probable cause of ...

Proventriculus of Cephalotes ants: A structural and comparative analysis

Micron, 2010
The use of optic microscopy and scanning electron microscopy propitiated the comparative examination of the structure of the proventriculus bulb of Cephalotes atratus, Cephalotes clypeatus and Cephalotes pusillus. This portion of the digestive tract possesses highly sclerotized projections which act in the selection of victuals.
