“…As discussed previously, the chorioallantoic membrane, alone or alongside other structures, performs essential egg functions, some of which may still be unknown. This membrane has sometimes been applied as a model for virus isolation and identification in the production of bird vaccines (Abd El Hafez et al 2021 ), as well as an in vivo estrogen synthesis model (GILL et al 1983 ). Studies employing this membrane regarding other functions should be more thorough, due to the presence of certain compounds reported herein, such as the glycogen granules found in the allantois, which may be associated with glycogen synthase kinase-3 related to bird signaling, cognition and neuronal behavior (Alon et al 2011 ).…”

The greater rhea, Rhea americana , is a wild ratite of high scientific importance and significant and zootechnical value, especially considering the current development state of Brazilian poultry production, where research aimed at increasing the productivity of these animals has become extremely relevant. Studies concerning fetal attachments and embryonic development are paramount, as they can provide essential information concerning reproductive and nutritional animal management. However, a lack of information on greater rhea fetal morphology is noted. Therefore, the aim of the present study was to establish a standard model for fetal attachments in this species. Greater rhea eggs were incubated from 0 to 36 days, and macroscopic and microscopic embryonic attachment characterizations were performed. Histologically, all embryonic annexes exhibit germ layers, namely the ectoderm (outer layer), mesoderm (middle layer) and endoderm (inner layer). The findings indicate that greater rhea development patterns are similar to other birds.
