The virus of transmissible enteritis of turkeys was shown to be an enveloped pleomorphic particle with an average diameter of 110 nm (range 60-250 nm). The surface bore tubular projections about 12 nm long. The internal component was very fragile, and could not be demonstrated in situ. It appeared as a helix, with a diameter of approximately 7 nm. Hemagglutination could not be demonstrated, but...

Approximately 9 billion chickens and 270 million turkeys are raised for meat annually in the United States. When these farmed birds reach market weight, they must be caught and crated for transport from production facilities to slaughter plants. Conventional manual catching results in severely compromised welfare. Birds experience stress and fear, and can be physically harmed, suffering bruises...

Levels of cardiac glycogen were determined by biochemical assays in turkey poults from an experimental flock with a known high incidence of round heart disease. Levels of cardiac glycogen were significantly higher (p < .05) than in commercial turkeys, but not significantly different in the turkeys that developed spontaneous round heart disease. The high level of cardiac glycogen in the poults o...

The aim of the present study was to determine the pharmacokinetics of simvastatin (SIM) administered orally in 6-week-old turkeys at a single dose of 2 mg/kg b.w. The SIM concentrations in plasma were determined by validated HPLC-MS/MS method. Mean (+/- SD; n = 10) values of pharmacokinetic parameters evaluated were as follows: Cmax = 0.49 +/- 0.21 ng/ml, t(max) = 1.6 +/- 1.1 h, AUC(0-infinity)...

Fats and oils, a.k.a. lipids, are a chemically diverse group of compounds with the highest energy density among all major macro nutrients. Lipids play an important role in commercial turkey diets both physically and physiologically. From a physical standpoint, lipids are associated with processes related to improvement of live weight gain and feed efficiencies in commercial turkeys. Breeder tur...

The present study was carried out to determine the effects of a different content of fructooligosaccharides (FOS) on the performance and intestinal metabolism in turkeys. Diets containing 0%, 0.5%, 1% and 2% of FOS, fed to turkeys for 8 weeks, had no effect on feed intake, body weight and feed conversion. The highest FOS content significantly increased the weight of caecal digesta, and lowered ...

A thin-layer chromatography technique was used to study the arginine metabolism of Mycoplasma meleagridis. The technique reflected the enzyme activity of the dihydrolase pathway through detection of readily visible end products on X-ray film. Strains of M. meleagridis differing in their pathogenicity for turkeys did not vary in arginine metabolism. In addition, no significant difference was obs...

Bordetella hinzii is a Gram-negative bacterium known to infect poultry, humans, rabbits, and rodents. It is an opportunistic pathogen in immunocompromised humans, and some strains cause mild to moderate respiratory disease in turkeys. Little is known as to the degree of genetic diversity within the species or the genetic basis for virulence. Here, we report the genome sequences of six isolates ...

Abstract Introduction The increasing resistance of bacteria to antibiotics has obliged the EU Member States reduce by 50% use in animal production 2030. This study was undertaken with aim analyse flocks broiler turkeys reared Warmia and Mazury province a two-year period. Material Methods From data from 238 records turkey provided County Veterinary Inspectorates, (mg/kg) analysed 2019–2021. year...

It was the purpose of these experiments to describe gonadal development and posthatching growth of genetic female chickens and turkeys following in ovo injection of the aromatase inhibitor Fadrazole (CGS 16949A) prior to incubation. In ovo injection of Fadrazole (CGS 16949A) resulted in the development of testes-like gonads in the majority of day-old genetic female chickens and turkey poults. N...
