Poultry birds. Domestic fowl and broiler are constantly in exposure of both ecto-parasites and endoparasites. The parasitic infestation badly affect the industry in various ways, low weight birds, meat with low quality in taste and nutrients, weight reduction etc. The present study shows that broiler bird is less infected by ecto-parasites and gastrointestinal; parasites as compared to domestic...

HE lack of an ancestral “standard of reference”, “normal” or “wild type” T for use in genetic studies of the domestic fowl has been of little concern to many poultry geneticists (for a recent discussion of this topic see JAAP and HOLLANDER 1954). In the field of plumage color inheritance, however, a standard of reference seems necessary in describing the action of mutant genes. What the standar...

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...

We describe a genetic variation map for the chicken genome containing 2.8 million single-nucleotide polymorphisms (SNPs). This map is based on a comparison of the sequences of three domestic chicken breeds (a broiler, a layer and a Chinese silkie) with that of their wild ancestor, red jungle fowl. Subsequent experiments indicate that at least 90% of the variant sites are true SNPs, and at least...

SKADHAUGE, ERIK, AND BODIL SCHMIDT-NIELSEN. Renal function in domestic fowl. Am. J. Physiol. 2 12 (4) : 793-798. 1967.Roosters were exposed to water and salt loading and to dehydration. The ureteral urine was collected through polyethylene funnels. The glomerular filtration rate (GFR) was found to increase an average of 23 yO from dehydration to hydration, when at the same time the urine flow i...

The rapid outbreak of the highly pathogenic A/H5N1 avian influenza virus among domestic birds and its transmission to humans have induced world-wide fears of a new influenza pandemic. If a human-trophic strain of A/H5N1 is replicated in domestic animals, it might have high transmissivity and pathogenicity to humans. If the misassembling of both avian and swine influenza viruses occur in the sam...

a survey of helminth parasites of domestic fowl carried out in faisalabad (pakistan) between 1994 and 1996 showed a high prevalence of nemaodes infestation in broiler and local poultry. ascardia galli and heterakis spp. were more prevalent in both groups of birds. syngamus tracheae and capillaria spp. were also present in both groups . raillietina spp. were the only cestode found in both the gr...

This chapter provides brief descriptions of diseases that 1) more commonly are found in small, backyard poultry flocks, or 2) are more significant economically or personally when they do occur. Further reading on these and many other diseases is recommended. All Poultry Types. Two important diseases shared by chickens, turkeys, guinea fowl, partridges, pheasants, quail, and domestic waterfowl (...

Today the developments in genetics are exciting. Perhaps this explains why geneticists sometimes seem to overlook common sense solutions. One example of this is the selection experiment done by Bijma et al. (2007a,b). These authors developed a sophisticated statistical method of group selection against mortality in hens randomly placed together. One may safely assume that this mortality is due ...
