Wild Turkeys (Meleagris gallopavo) are susceptible to many of the same diseases as domestic turkeys. Before 2005, most Wild Turkeys in southern Georgia, US, had little or no exposure to commercial poultry operations. As part of a pathogen survey examining the effects of commercial poultry on Wild Turkeys, samples were collected from Wild Turkeys from March 2005 through May 2008. The turkeys wer...

Production results were compared for two groups of turkeys reared in semi-intensive system. The material included 40 primitive turkeys of the light type and 40 heavy hybrids of the Big-6 line (commercial flock). Females was raised to 14 and males to 22 weeks of life. During the rearing, body weight (g) was controlled individually and feed intake (g) was monitored in groups, in weekly intervals....

The study was conducted to investigate the effects of wheat based diet on the pathology of necrotic enteritis in turkeys. Turkeys were divided into four groups. Groups A and B were kept as noninoculated and fed normal commercial diet while groups C and D were challenged orally with C. perfringens and fed wheat based diet to promote the development of experimental disease. Infected turkeys showe...

Several previous reports and our studies show that waterfowl-origin influenza viruses can be more easily transmitted to domestic turkeys than chickens. Similarly, studies indicate turkeys to be better hosts for low pathogenic avian influenza viruses isolated from commercial poultry operations and live bird markets in comparison to chickens. Low 50% infectious-dose titers of wild bird as well as...

background: it is important to understand the efficacy of immunoregulatory materials, herbal remedies or probiotics, in different parts of immune system following vaccination with different tropism. objectives: aim of this study was to evaluate the effect of echinacea purpurea and a probiotic (protexin) on systemic and mucosal immune response in turkey. methods: a total of 288 1-day-old male tu...

The article presents the results of monitoring parasitic protozoa young turkeys in industrial-type farms Central region Russia. Fecal samples, scrapings from floor and passages, contents gastrointestinal tract during slaughter were systematically examined birds different ages. age seasonal dynamics their infection with eimeria, as well contamination environmental objects by protozoan oocysts, e...

In this study the macroscopic and microscopic structure of the heart of a fast growing, meat-type turkey line (British United turkeys BUT Big 6) and a wild-type turkey line (Canadian Wild turkey) were compared. At 8 and 16 weeks of age, 10 birds of each genotype and sex were sampled. The body mass and heart mass of the meat-type turkey both increased at a faster rate than those of the wild-type...

The effects of hydralazine on aortic rupture, hemodynamics and aortic ultrastructure were studied in turkeys fed B-aminopropionitrile (BAPN). A mortality rate of 24% due to hemopericardium and internal hemorrhage in turkeys fed only BAPN increased to 91% when turkeys were fed both BAPN and hydralazine, despite a significant reduction in blood pressure after both drugs. Death rates among turkeys...

Wild turkeys, Meleagris gallopavo, are among the most ornamented birds in North America, displaying vividly coloured fleshy ornaments on their heads and bright, iridescent structural coloration in their plumage. We investigated the effect of experimental inoculation with coccidian parasites on the expression of iridescent structural coloration in yearling male turkeys. Prior to moult of ornamen...

Previous studies using zearalenone (ZEN) and fumonisins (FB) revealed alpha-zearalanol (?-ZOL) FB1 in the liver of turkeys chickens with no sign toxicity. The aim present study was to determine whether contamination persists after distribution a mycotoxin-free diet for several days. Turkeys broilers were fed 14 days containing respectively, 7.5 0.6 mg/kg FB ZEN, then 0, 2 or 4 diet. total ?-ZOL...
