The performance of naked neck and normal chicken was evaluated with respect to growth, carcass, immune, biochemical and stress parameters under winter and summer seasons to assess the suitability of naked neck birds under high temperatures in the global scenario of climate change. The growth performance was significantly (p≤0.05) higher in naked neck chicken in the summer season. The dressing p...

The individual feathers in the skin of a developing chicken embryo are arranged in a precise array within a series of so-called 'tracts'. The images above show nascent feather buds in the legs of embryos at 8–9 days of incubation. Buds are added sequentially across the forming feather tract, as shown by the range of developmental stages in the image at top left. (In all three upper images, buds...

Background; Feather waste is generated in large amounts as a by-product of commercial poultry processing. The main component of feather is keratin. The main purpose of this study was to identify Bacillus spp. (the keratinolytic bacteria) that are able to degrade the feather for producing keratin. Methods; Bacillus spp. Were isolated from the waste of poultries located in Miyaneh city. The bact...

Nitroimidazole compounds have been traditionally used in the veterinary and human medicine, but their uses are sometimes associated with some side effects. Toxicopathological effects of nitroimidazoles have always been a major concern. There is scant information available about the pathological alterations of nitroimidazole compounds in the embryo. The objective of this study was to determine t...
