Previous work suggests domestic poultry are important contributors to the emergence and transmission of highly pathogenic avian influenza throughout Asia. In Poyang Lake, China, domestic duck production cycles are synchronized with arrival and departure of thousands of migratory wild birds in the area. During these periods, high densities of juvenile domestic ducks are in close proximity to mig...

Indigenous ducks play a vital role in sustainable livelihood of the poor duck farmers. In Tamil Nadu, two popular indigenous duck varieties viz., Sanyasi and Keeri are being reared traditionally by the duck farmers under nomadic system. In the same way, Kuttanad ducks are popular in Kerala and Assam ducks are popular in Assam. The present research work was undertaken to study the genetic distan...

The cherry tomatoes online sorting according to their maturity is an important procedure after harvest. This research proposed an automated cherry tomato grading system base on machine vision. Three images of different angles are obtained from each cherry tomato, allowing the inspection of approximately 90% of the fruit surface. 9 features were extracted from the one cherry tomato images. In or...

The similarity of the louse faunas of flamingos and ducks has been used as evidence that these two groups of birds are closely related. However, the realization that ducks actually are more closely related to Galliformes caused many workers to reinterpret this similarity in parasite faunas as host switching from ducks to flamingos. Recent unexpected phylogenetic results on the relationships of ...

Controversy has developed as to whether or not pin-metered water lines or water troughs are more appropriate for Pekin ducks. We hypothesized that water troughs would show improved duck body conditions and environmental quality compared to pin-metered water lines. To test this hypothesis, we housed ducks in 2 barns, one with water lines and one with water troughs. Water troughs were constructed...

The purpose of this study was to identify Follicle Stimulating Hormone (FSH) gene mutation West Sumatera Pitalah ducks. This used blood samples from 50 ducks (5 males and 45 females). Extraction analized by Kit iNtRON Biotechnology amplification DNA extraction the primer with fragmen target 318 bp. Sequencing 1st Base Singapore product Dnastar. Based on result is ducks.
 Key Words: FSH, Ge...

Ducks are important maintenance hosts for avian influenza, including H5N1 highly pathogenic avian influenza viruses. A previous study indicated that persistence of H5N1 viruses in ducks after the development of humoral immunity may drive viral evolution following immune selection. As H5N1 HPAI is endemic in Indonesia, this mechanism may be important in understanding H5N1 evolution in that regio...

Until 2002, H5N1 highly pathogenic avian influenza (HPAI) viruses caused only mild respiratory infections in ducks. Since then, new viruses have emerged that cause systemic disease and high mortality in ducks and other waterfowl. Studies on HPAI virus pathogenicity in ducks have been limited, and there is no clear explanation of why the pathogenicity of some H5N1 HPAI viruses has increased. The...

GERZILOV, V. and P. PETROV. Relationship between some blood biochemical parameters and fatty liver weight in force feeding of mule ducks. Bulg. J. Agric. Sci., 21: 1039–1043 The purpose of this study was to determine the phenotype correlation between fatty liver weight (FLW) and some blood serum biochemical parameters in mule ducks – alanine aminotransferase (ALAT), aspartate aminotransferase (...

Immunofluorescence assays with fixed tissue sections were used to characterize antibody reactivity in sera obtained from duck hepatitis B virus-infected ducks. Under conditions of experimental infection, antibody to core antigen but not to surface antigen was detectable. A majority of the ducks infected at 8 days after hatching and a minority of those infected at 1 day after hatching showed a t...
