The calling on livestock is increasing fast because of the population and economic broadening. In recent years, contribution sector to greenhouse gas emissions climate change has been a concern. This accounts for second largest share anthropogenic after energy sector. storage animal manure very important in this respect. Because gases such as nitrous oxide methane, which are gases, formed durin...
Interferons, as the first line of defense against the viral infection, play an important role in innate immune responses. Type III interferon (IFN-λ) was a newly identified member of IFN family, which plays IFN-like antiviral activity. Towards a better understanding of the type III interferon system in birds, type III interferon lambda receptor (IFNLR1) was first identified in the Chinese goose...
Duck Tembusu virus (TMUV), an emerging avian flavivirus, is highly pathogenic to birds and has the potential to become a zoonotic pathogen. Here, the molecular antiviral mechanism of goose type I, II, and III interferon (goIFNα, goIFNγ, and goIFNλ), the key components of the innate immune pathway, against TMUV was studied. We found that the transcription of goIFNs was obviously driven by TMUV i...
A restriction fragment length polymorphism combined with direct PCR technique to differentiate goose and Muscovy duck parvoviruses (GPV and MDPV) was developed based on comparison of the NS gene of GPV and MDPV. Both GPV and MDPV genomic DNA can be amplified with 641 bp using the specific PCR primers. The PCR fragments can be cut into 463 bp and 178 bp only in the case of MDPV-derived PCR produ...
In this study, we report the establishment and characterization of a new epithelial cell line, goose embryonated epithelial cell line (GEE), derived from embryonic goose tissue. The purified GEE cell line can efficiently grow over 65 passages in the M199 medium supplemented with 10% fetal bovine serum at 37°C. Immunofluorescence assay was used to identify purified GEE cells as epithelial cell l...
Von Baer (1828) formulated a rule according to which the cephalo-caudal axis is perpendicular to the long axis of the shell, and the head of the embryo is directed forwards when the egg is placed with the blunt end to the left. This law has been checked in several species of bird: hen, duck, pigeon, goose, turkey (see Clavert, 1960, for references) and quail (Fargeix, 1963, 1964). Embryos obeyi...
