Lymphoproliferative disease virus (LPDV) is a poorly understood, oncogenic avian retrovirus of domestic turkeys that has historically been restricted to Europe and Israel. However, a recent study reported LPDV in multiple wild turkey diagnostic cases from throughout the eastern United States of America (USA). To better understand the distribution of LPDV in the eastern USA, we surveyed 1,164 re...

Triple reassortant (TR) H3N2 influenza viruses have been isolated from turkeys in the United States since 2003. These TR H3N2 virus infections have been associated with drastic declines in egg production in breeder turkeys although co-infection with multiple agents could have been responsible for exacerbating the clinical signs. In this study, we experimentally confirmed that TR H3N2 influenza ...

BACKGROUND Toxoplasmosis is a parasitic disease caused by the protozoan Toxoplasma gondii. This parasite infects most of warm-blooded animals, including birds. Turkeys are one of these animals which might be infected by this parasite. Little is known about the prevalence of T. gondii in turkeys in Iran. OBJECTIVES The current study aimed to evaluate the rate of Toxoplasma infection in turkeys...

The performance of animal in a given environment differs between and within species, breeds strains genotypes, as result genetic variation. A total 200 turkeys comprising 50 exotic (Nicholas white) each Nigerian locally adapted (black, white lavender) was used to investigate variation body weight some biometric traits turkey at the Turkey Breeding unit Teaching Research Farm Ambrose Alli Univer...

This study was conducted to compare three non-linear growth models (Logistics, Gompertz and Von Bertalanffy) in describing the of 360 turkeys genotypes (exotic, crossbred local). The curve parameters - A, B K for each model were estimated turkey using NLIN procedure (Marquart algorithm) Bayesian approach with a fixed-effect model. best fit also estimated. A comparison done among Akaike Informat...

The aim of this study was to evaluate the influence of long-term denervation on volumetric bone mineral density, and geometrical and mechanical properties of the humerus in turkeys. The experiment was conducted from d 22 after hatching until wk 17 of life. All experimental birds (male turkeys) were randomly divided into 2 weight-matched groups. The first group of turkeys served as the control g...

Infectious bursal disease virus (IBDV) in turkeys may result in immunosuppression, and inability of turkeys to resist nonpathogenic or less pathogenic organisms. A total number of 120 day-old commercial male turkeys were purchased and blood samples were collected from 20 day-old turkeys, remaining 100 were divided into four equal groups and kept in separated rooms. Groups 1 and 2 were infected ...

Domestic turkeys (Meleagris gallopavo) are one of the most susceptible animals known to the toxic effects of the mycotoxin aflatoxin B1 (AFB1), a potent human hepatocarcinogen, and universal maize contaminant. We have demonstrated that such susceptibility is associated with the inability of hepatic glutathione S-transferases (GSTs) to detoxify the reactive electrophilic metabolite exo-AFB1-8,9-...

Two experiments were conducted to investigate the differences in susceptibility to foot pad dermatitis (FPD) of two medium-heavy lines of turkeys, and whether FPD is painful, by detailed analysis of behaviour in birds with and without analgesic treatment (betamethasone). Turkeys housed on dry litter in the first experiment generally had more frequent bouts of different behaviours that were of s...
