We describe a new species of extinct duck, Miotadorna catrionae sp. nov. (Anatidae, Tadornini, Tadorninae), based on right humerus from the Miocene lacustrine deposits St Bathans, Otago, New Zealand. Principal component analysis reveals that taxon is distinguished by its large size and relative proportions. This eighth largest duck described Bathans fossil assemblage further underscores global ...
This research aimed to determine the effect of combination pineapple and papaya fruit quintessence on pH, water holding capacity, tenderness meat post production laying duck. was conducted in December 2019 January 2020 at Production Reproduction Livestock Laboratory, Instrument Faculty Agriculture University Lampung. The materials this used were 20 pieces thigh a Completely Randomized Design (C...
An outbreak of egg drop disease occurred in many chicken and goose farms in China in 2011. By using an NS5-specific reverse transcriptase PCR (RT-PCR), we found that 56% of chicken and 38% of goose samples were positive for Tembusu-like virus (TMUV). Isolates showed high sequence homology to duck TMUVs, and chickens and geese showed signs of egg drop disease after experimental infection with du...
In this study, we report the complete genome sequence of a novel Newcastle disease virus (NDV) strain, Sheldrake duck/China/Guizhou/SS1/2014, isolated from Sansui Sheldrake duck flocks in Guizhou Province, southwestern China. The genome of this isolate is 15,192 nucleotides in length, which belongs to NDV genotype VIId in class II. This discovery will help us further study the epidemiology char...
We report here the complete genome sequence of a novel reassortant H4N2 avian influenza virus strain, A/duck/Guangxi/125D17/2012(H4N2) (GX125D17), isolated from a duck in Guangxi Province, China in 2012. We obtained the complete genome sequence of the GX125D17 virus isolation by PCR, cloning, and sequencing. Sequence analysis revealed that this H4N2 virus strain was a novel reassortant avian in...
The first complete genome sequence of a strain of Newcastle disease virus (NDV) of genotype XVII is described here. A velogenic strain (duck/Nigeria/903/KUDU-113/1992) was isolated from an apparently healthy free-roaming domestic duck sampled in Kuru, Nigeria, in 1992. Phylogenetic analysis of the fusion protein gene and complete genome classified the isolate as a member of NDV class II, genoty...
