GROWTH OF THE CHICKEN EMBRYO AND ITS REPRODUCTIVE ORGANS [PDF]

open access: yesVolga Region Farmland, 2020
The article is devoted to the analysis of the relative increase in the mass and length of the chick-en embryo and its reproductive organs. Based on the data obtained, the asynchrony of changes in the studied indicators is found.

Teratogenic of 2,3,7,8-Tetrachlorodibenzo-P-Dioxin (TCDD) on Eye Diameters and Body Weight in Chicken Embryo

open access: yesJurnal Medik Veteriner, 2021
2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a chemical compound resulting from the burning effect that is very dangerous for humans, plants, or animals which can cause skin damage, immunotoxic, hepatotoxic, carcinogenic, teratogenic, effects on ...

Transcriptomic analysis reveals the dynamic changes of transcription factors during early development of chicken embryo

open access: yesBMC Genomics, 2022
Background The transition from fertilized egg to embryo in chicken requires activation of hundreds of genes that were mostly inactivated before fertilization, which is accompanied with various biological processes. Undoubtedly, transcription factors (TFs)

Insights into Gonadal Sex Differentiation Provided by Single-Cell Transcriptomics in the Chicken Embryo.

open access: yesCell Reports, 2020
Although the genetic triggers for gonadal sex differentiation vary across species, the cell biology of gonadal development was long thought to be largely conserved.

Chicken embryo development: metabolic and morphological basis for in ovo feeding technology

open access: yesPoultry Science, 2020
Broiler embryonic development depends on the nutrients that are available in the egg, which includes mostly water, lipids, and proteins. Carbohydrates represent less than 1%, and free glucose only 0.3%, of the total nutrients.

Bioengineered three‐dimensional transparent eggshell as a chicken embryo experimentation platform for biomedical research

open access: yesEngineering Reports, 2020
The chicken embryo is widely used as an experimental model in the areas of regenerative medicine, tumor biology, and angiogenesis. Eggshell opacity and rigidity present restricted three‐dimensional (3D) viewing and accessibility to the embryo and its ...

Composition of omega-3 and omega-6 fatty acids in freeze-dried chicken embryo eggs with different days of development [PDF]

open access: yesBrazilian Archives of Biology and Technology, 2004
Fatty acids omega--3 and omega--6 composition and specially DHA were determined in freeze-dried chicken embryo eggs with pre-determined incubation periods. Fertile and embryo eggs presented palmitic (23.18 + 0.54%), stearic (7.70 + 0.28%), palmitoleic (3.

Relationship between phylogenetic groups of Escherichia coli and Pathogenicity among Isolates from chickens with Colibacillosis and healthy chickens

open access: yesPoultry Science, 2022
: Avian pathogenic Escherichia coli (APEC) is closely related to extraintestinal pathogenic E. coli, which are frequently assigned to specific phylogenetic groups (phylogroups). Therefore, we investigated the association between phylogroups of E.

The chicken embryo and its micro environment during egg storage and early incubation [PDF]

open access: yes, 2008
When egg storage periods are prolonged (>7 days), hatchability and chick quality declines. The reason for this decline has been investigated, but is still not completely understood.
