chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (pufas) are required for both animal and human health. the n-3 pufas, especially, eicosapentaenoic acid (epa) and docosahexaenoic ...

in order to perform breeding programs and improve production of native chickens, preserving genetic diversity in different areas of iran is important due to the reduced available population. genome sequencing is considered the most functional approach to determine the phylogeny relation between close populations. the aim of the present study was the evaluation of the phylogeny and genetic nucle...

despite of beneficial effects of antibiotics in treatments of infectious diseases, antibiotic residues in meat, milk, eggs and another products can cause serious side effects for human health. it is clear that, antibiotic residues in food stuff, cause bacterial resistance, allergic reactions, toxicity, carcinogenic effects and change of natural micro flora of intestine in consumers. so, the aim...

in order to show the type and severity of gross and histopathologic lesions induce by vaccinal strain (serotype a1) of pateurella mulocida, ten four-week-old spf chickens were inoculated intramuscularly with 75 cfu of ( 0.5 ml of 10-7 dilution) bacterium. all birds died in less than 16 hours. no prominent gross lesions were observed in different organs. in microscopic examination, the most comm...

Methotrexate (1 muM) abolishes the proliferation of chicken fibroblasts in a culture medium containing defibrinogenated chicken plasma but does not affect proliferation in a medium containing chicken serum.

Aim: To study the prevalence of pathogenic coagulase positive, methicillin-resistant Staphylococcus aureus (MRSA) in poultry meat and its products. Materials and Methods: A total of 125 poultry samples were collected during 2012 in Qena governorate for presence of pathogenic coagulase positive, methicillin-resistant staphylococcus aureus (MRSA). Samples were taken from freshly slaughtered whole...

Myosin light chain kinase purified from chicken white skeletal muscle (Mr = 150,000) was significantly larger than both rabbit skeletal (Mr = 87,000) and chicken gizzard smooth (Mr = 130,000) muscle myosin light chain kinases, as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Km and Vmax values with rabbit or chicken skeletal, bovine cardiac, and chicken gizzard smooth...

The chicken retina contains rhodopsin (a rod visual pigment) and four kinds of cone visual pigments. The primary structures of chicken red (iodopsin) and rhodopsin have been determined previously. Here we report isolation of three cDNA clones encoding additional pigments from a chicken retinal cDNA library. Based on the partial amino acid sequences of the purified chicken visual pigments togeth...

This study is conducted to evaluate the effects of the mixing ratio between pork loin and chicken breast for textural and sensory properties of emulsion sausages. Meat homogenates are prepared by using five mixing ratios between pork loin and chicken breast (100:0, 70:30, 50:50, 30:70, and 0:100), and the emulsion sausages are also formulated with five mixing ratios. The additions of chicken br...

Monoclonal antibodies (MAbs) are invaluable molecules which have several advantages over polyclonal immunoglobulins (Igs) including consistency and higher specificity and hence can be used in biological researches, diagnosis and treatment of diseases. The present study was conducted to produce monoclonal antibody against chicken IgG.TheIgG molecules were purified from chicken serum and used as ...
