China is the largest producer and consumer of geese with significant social economic value in agriculture. The Jilin White Goose, known for its excellent egg-laying reproductive characteristics, a prominent breeding breed northeast widely used cross-breeding.Gonad development complex process, which will differentiate into testes or ovaries, thus affecting sex determination. Since level gonadal different sexes also related to their productivity, study function great theoretical practical...
Testicular development is essential for reproductive performance in geese, as the testes are primary organs sperm production and play a pivotal role egg-laying physiology. Despite their importance, genes, proteins, pathways regulating goose testicular poorly understood. This study employed integrative transcriptomic proteomic analysis methods to identify critical regulators of geese across three periods. Additionally, PKCα Sertoli cell proliferation via MAPK/ERK pathway was evaluated at...
Abstract Background Jilin white goose is an excellent local breed in China, with a high annual egg production and laying eggs mainly from February to July each year. The testis, as the only organ that can produce sperm, affect sexual maturity fecundity of male animals. Its growth development are affected regulated by variety factors. Proteomics generally applied identify quantify proteins cells tissues order understand physiological or pathological changes occur under specific conditions....
The Wingless-types/beta-catenin (Wnt/β-catenin) signaling pathway plays an important role in embryonic development and affects the physiological processes of feather follicles. To investigate Wnt/β-catenin regulating follicles morphogenesis, ovo injection CHIR-99021, activator pathway, was conducted chick embryo model. Initially, a total 40 embryos were used to assess morphogenesis expression β-catenin (E9–E17). histological results showed that follicle mainly completed from E9 E17. involved...
In production practice, we have found that the gray and black down on backs of Holdobaggy goslings is usually darker in females than males. Melanin key pigment affecting color poultry plumage. Therefore, to determine whether darkness dorsal plumage related sex, study melanin feather follicles skin during embryonic period. The follicle structure distribution surface goose embryo observed by HE staining melanin-specific staining. content determined ELISA. results showed higher female geese...
Skin and feather follicle development are essential processes for goose embryonic growth. Transcriptome next-generation sequencing (NGS) network analyses were performed to improve the genome of Zhedong White discover critical genes, miRNAs, pathways involved in skin morphogenesis. Sequencing output generated 6,002,591,668 8,675,720,319 clean reads from fifteen libraries. There 1234, 3024, 4416, 5326 different genes showing differential expression four stages, E10 vs. E13, E18, E23, E28,...
The present study was performed to investigate the effects of dietary supplementation with herbal additives on meat quality, slaughter performance and cecal microbial community in Hungarian white geese. A total 60 newborn geese were assigned equally into control group (CON) complex supplemented (HS). supplementations consisted Compound Herbal Additive (CHAA) including Pulsatilla, Gentian Rhizoma coptidis , B (CHAB) containing Codonopsis pilosula, Atractylodes, Poria cocos Licorice . HS...
Goose down feather has become one of the most important economical products in goose breeding industry and it provides several essential physiological roles birds. Therefore, understanding regulating development skin follicles during embryogenesis is critical for avian biology poultry industry. MicroRNAs are known to play an role controlling gene expression follicle development. In this study, bioinformatics analysis was conducted select miR-140-y as a potential miRNA involved predict TCF4...
The goose industry represents a significant sector within the broader waterfowl in China, with early gonadal development playing pivotal role enhancing population productivity. Melatonin plays crucial regulating development, but molecular mechanism underlying effect of melatonin as regulator remains unclear. In this study, relationship between and egg production performance Jilin white was first established, then, an Ovo injection embryos on embryonic day 12 (E12) performed to evaluate...
Feather performs important physiological functions in birds, and it is also one of the economic productions goose farming. Understanding modulating feather follicle development during embryogenesis are essential for bird biology poultry industry. CHIR-99021 a potent Wnt/β-catenin signaling pathway activator associated with development. In this study, embryos (Anser cygnoides) received an ovo injection CHIR-9902, which was conducted at beginning (E9). The results showed that growth were...
Poultry is subject to varying degrees of feather loss and pecking during production, which seriously affects the live appearance carcass their commercial traits greatly reduces production profitability farming enterprise. It also has an impact on down quality in case geese. In this study, mathematical models (Logistic, Gompertz, Von Bertalanffy) were used assess growth development embryonic period Jilin white geese (Anser cygnoides) predicting weight length feathers from back, chest, belly...
In order to enrich the Anser cygnoides genome and identify gene expression profiles of primary secondary feather follicles development, de novo transcriptome assembly skin tissues was established by analyzing three developmental stages at embryonic day 14, 18, 28 (E14, E18, E28). Sequencing output generated 436,730,608 clean reads from nine libraries assembled into 56,301 unigenes. There were 2,298, 9,423 12,559 unigenes showing differential in respectively. Furthermore, differentially...
Abstract Background Hungarian white goose has excellent down production performance and was introduced to China in 2010. The growth development of feather follicles an important impact on production. Goose can be divided into primary secondary follicles, both which originate the embryonic stage. Msx2 (Msh Homeobox 2) plays a regulatory role tissues organs such as eyes, teeth, bones skin. However, its mechanism remains unclear. Results gene first increased, then decreased increased at end...
The Hungarian White Goose (Anser anser domesticus) is an excellent European goose breed, with high feather and meat production. Despite its importance in the poultry industry, no available genome assembly information has been published. This study aimed to present Chromosome-level functional sequencing of Goose. results showed that a total length 1115.82 Mb, 39 pairs chromosomes, 92.98% BUSCO index, contig N50 scaffold were up 2.32 Mb 60.69 respectively. Annotation revealed 19550 genes, 286...
Egg production performance is an important economic trait in the poultry industry. In previous studies, attention has often been paid to growth and development of ovaries, while there less research on testicular tissue male goose. Due various factors, are usually significant differences process spermatogenesis among different goose breeds.
