/globulin ratio. Significant variations were not observed in the analyses in relation to the age of birds for serum total protein, albumin and globulins. The albumin/globulin ratio showed significant difference among 21 and 49 day-old Chinese geese. Key words: Anser cygnoides; blood proteinogram; total serum

Background: The geese have strong broodiness and poor egg performance. These characteristics are the key issues that hinder the goose industry development. Yet little is known about the mechanisms responsible for follicle development due to lack of genomic resources. Hence, studies based on high-throughput sequencing technologies are needed to produce a comprehensive and integrated genomic resource and to better understand the biological mechanisms of goose follicle development. Methodology/Principal Findings: In this study, we performed de novo transcriptome assembly and gene expression analysis using short-read sequencing technology (Illumina). We obtained 67,315,996 short reads of 100 bp, which were assembled into 130,514 unique sequences by Trinity strategy (mean size = 753bp). Based on BLAST results with known proteins, these analyses identified 52,642 sequences with a cut-off E-value above 1025. Assembled sequences were annotated with gene descriptions, gene ontology and clusters of orthologous group terms. In addition, we investigated the transcription changes during the goose laying/broodiness period using a tag-based digital gene expression (DGE) system. We obtained a sequencing depth of over 4.2 million tags per sample and identified a large number of genes associated with follicle development and reproductive biology including cholesterol side-chain cleavage enzyme gene and dopamine beta-hydroxylas gene. We confirm the altered expression levels of the two genes using quantitative real-time PCR (qRT-PCR).

Abstract: Clinical and immunological parameters of vaccinated Chinese goose against Newcastle disease were evaluated. One hundred and twenty birds were distributed into four different experimental groups, vaccinated or not against Newcastle disease (ND): G1 (Ulster 2C strain), G2 (B1 strain), G3 (LaSota strain) and G4 (nonvaccinated-control).The immune response was evaluated by the HI test. The vaccinations of Chinese geese with NDV Ulster 2C, B1 and LaSota strains did not cause any clinical signs associated with post-vaccinal reactions and were similar in the humoral immune response stimulus (HI). Key words: Chinese goose, vaccination, newcastle disease, ulster 2C, B1 and lasota strains

In 2006–2008, 25 Swan Geese Anser cygnoides were marked with solar-powered GPS satellite transmitters in northeast Mongolia to examine the timing and pathways of their migration. Most geese began their autumn migration in August, flying southeast toward a staging area at the Yalu River Estuary

Abstract. The transcription factors GATA-4 and GATA-6, members of the GATA family, play an important role in ovarian cell proliferation, differentiation and apoptosis. In this study, the full-length coding sequences of goose GATA-4 and GATA-6 were cloned and characterized. GATA-4 and GATA-6 consist of 1236 and 1104 nucleotides encoding proteins with 411 and 367 amino acids, respectively. The deduced amino acid sequences of both proteins include two adjacent zinc finger domains with the distinctive form (CVNC-X17-CNAC)-X29-(CANC-X17-CNAC) and share 84.76 % identity within this domain. In silico prediction together with matching of the high affinity RRXS(T)Y motif revealed that the GATA-4 protein might be phosphorylated predominantly at S233, but no phosphorylation site was found in the GATA-6 protein. Real-time quantitative PCR analysis showed that GATA-4 and GATA-6 mRNAs were co-expressed in goose follicles, moderately expressed in granulosa cells and weakly expressed in theca cells. The expression level of GATA-4 mRNA in healthy follicles was significantly higher than in atretic follicles or postovulatory follicles (P<0.01), and the expression level of GATA-6 mRNA in healthy follicles was significantly lower than in atretic follicles or postovulatory follicles (P<0.01). The expression level of GATA-4 mRNA in granulosa cells was downregulated during follicle development; the peak of expression occurred in the 8-10 mm follicles, and the lowest expression was in the F1 follicles. GATA-6 was upregulated and reached its peak expression in the F1 follicles. These results indicate that the molecular structural differences in goose GATA-4 and GATA-6 may be related

Domestic ducks and geese trace back to two species of waterfowl each: the mallard duck (Anas platyrhynchos) and the muscovy duck (Cairina moschata), the greylag goose (Anser anser) and the swan goose (Anser cygnoides). Ducks and geese were known in ancient China and Egypt, where they had already

Fibromas are the benign neoplasms of fibrocytes with abundant collagenous stroma. The majority of the tumors are round to oval intradermal or subcutaneous masses (Hendrick, 2002). History and Clinical Examination A Fifteen year old goose (Anser cygnoides) was brought to the College Hospital with a

Abstract: This study aimed the characterization of the importance of vaccination against Newcastle disease in Chinese geese (Anser cygnoides) and to investigate the state of carrier of the virus in this species. There were used 120 Chinese geese, distributed at random into 4 groups, vaccinated

Summary. The life cycle and pathogenicity of Eimeria fulva were studied. Eighteen, 10-day-old, artificially-reared coccidia-free goslings (Anser cygnoides var. domestica) were inoculated orally with 7.0×10 5 -1.5×10 6 sporulated oocysts of Eimeria fulva and killed at intervals from 24 to 288 h
