Effect of maternal environment on yolk immunoreactive corticosterone and its influence on adrenocortical and behavioral activity in chicks of Greater Rhea (Rhea americana)
(Elsevier, 2019-08)Maternal corticosterone in avian eggs may modify offspring phenotype in order to increase survival in poor environments. In the Greater Rhea (Rhea americana), we previously found that yolk immunoreactive corticosterone is ... -
IgY against enterotoxigenic Escherichia coli administered by hydrogel-carbon nanotubes composites to prevent neonatal diarrhoea in experimentally challenged piglets
(2016-06-14)In previous studies, the applicability of polymeric hydrogels for the protection of egg yolk immunoglobulin (IgY) against simulated gastric conditions was established. Thereafter, the performance of the hydrogels was ... -
Relación yema: albumen en huevos de tres genotipos de gallinas ponedoras destinadas a sistemas semi intensivos
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, 2022-08-06)Se estudió el comportamiento dinámico de la relación yema:albumen en huevos del cruzamiento de tres vías Campero Casilda en comparación con Negra INTA y Rhode Island Red. Se trabajó con muestras aleatorias de 15 huevos de ... -
Yolk corticosterone and progesterone levels in Greater Rhea (Rhea americana) eggs vary in a changing social environment
(Wiley, 2022-07)Maternal hormones in avian egg yolks may signal and prepare offspring for the prevailing conditions. However, this adjustment requires some degree of flexibility in regulating yolk hormone deposition. The Greater Rhea (Rhea ...
