Plumage Color Allelism in the Red Jungle Fowl (Gallus Gallus) and Related Domestic Forms.
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).

متن کاملComparison of running energetics in male and female domestic fowl.
Carbon dioxide production (VCO2) and end-exercise venous lactate concentration were compared in intensively-trained, mature male and female domestic fowl running on a treadmill for 10-min periods at maximal and sub-maximal work loads. The relationship between VCO2 and running speed was linear and had the same slope in male and female birds. However the maximum sustainable running speed of the m...
متن کاملSocial environment and immunity in male red jungle fowl
We examined the relationship between social dominance, immune response, and ornamentation in captive red jungle fowl by comparing these variables in males housed individually with a single female to those in the same males after they were placed in flocks with an unfamiliar male and three unfamiliar females.
