The rapid discovery of novel viruses using next generation sequencing (NGS) technologies including DNA-Seq and RNA-Seq, has greatly expanded our understanding of viral diversity in recent years. The timely identification of novel viruses using NGS technologies is also important for us to control emerging infectious diseases caused by novel viruses. In this study, we identified a novel duck coro...

The phenomena of natural and acquired resistance to transplanted chicken tumors strikingly resemble those observed in the case of transplanted mammalian growths; and no more than those do they suggest that the tumors have an extrinsic cause. That there may exist in fowls implanted with a chicken tumor a resistance directed against the tumor-causing agent distinct from the resistance manifested ...

There is hardly any research data on the external anatomy of guinea fowls. Three hundred and sixty local fowls, involving 180 each males females were studied, documented developmental variations in these birds from hatching until adulthood. The study also explored call-based approach as an alternative sexing method birds. Externally, all changed brownish black-stripped down feathers at to white...

1. A preparation of completely haemolysed erythrocytes from the blood ofdomestic fowls, which actively incorporates [Ox-14C]glycine into haem, is described. 2. The effects of time and of glycine concentration on the rate of synthesis were studied. 3. Stimulation of the synthesis up to sixfold was obtained with some preparations of boiled yeast extract. 2:4-Dinitrophenol inhibited the synthesis ...

The luminance dependence of spatial acuity in domestic fowl was measured directly over stimulus luminances ranging from 0.06 to 57.35 cd m(-2). At the highest luminance, acuity was around 6.5 c deg(-1), in agreement with previous studies in this species. As stimulus luminance decreased, acuity fell with increasing rate to 3.2 c deg(-1) at 0.06 cd m(-2), following the same shape as acuity functi...

Fibres are not digested by fowls, but their impact on digestive physiology, nutrient metabolism and intestinal microflora can be substantial. Analytical shortcomings have historically contributed to different notions on the significance of fibres, but modern techniques now enable us to better discriminate between various fractions of fibre and relate them with the performance of poultry. The fo...
