Spondylitis in broiler breeder farms in West-Azerbaijan province, Iran: Clinical Report
Spondylitis is a reemerging epidemic spinal infection in male broiler chickens (5 to 7 weeks of age) as well as broiler breeder roosters (15 to 18 weeks of age). Among various causative agents, Enterococcus species and in particular E. cecorum, a gram-positive bacterium as a gastrointestinal flora of birds, have mostly been isolated. On late September 2015, a number of 10 week...
متن کاملIncidence and risk factors of Mycoplasma synoviae infection in broiler breeder farms of Iran
Mycoplasma synoviae (MS) is an important pathogen of poultry worldwide, causing respiratory tract infection and infectious synovitis in chickens and turkeys. The aim of this study was to determine the incidence and risk factors (age, size of flock, locale, sex and strain) of Mycoplasma synoviae in broiler breeder farms in Iran. The study was based on Rapid Serum Plate Agglutination (SPA) and en...

متن کاملSerological Survey of Avian Metapneumovirus Infection in Broiler Breeder Chicken Farms in Tamil Nadu
Avian metapneumovirus (aMPV) is an important poultry pathogen causing an acute highly contagious upper respiratory tract infection in chickens leading to swollen head syndrome. The disease can cause significant economic losses in turkey and chicken flocks, particularly when exacerbated by secondary pathogens. The purpose of this study was to determine the prevalence of avian metapneumovirus ant...
متن کاملPotential relationships between physical traits and male broiler breeder fertility.
Genetic selection in primary broiler breeders may modify skeletal structure, possibly impeding semen transfer, and could alter the size and degree of fluctuating asymmetry (FA) of bilateral traits associated with fertility. Hence, we hypothesized specific morphometric traits could predict differential fertility. Sixty primary broiler breeder males from Strains A and B (n = 30/strain) were indiv...
