This study aims to determine the histomorphometry of small intestine turkeys (Meleagris gallopavo) at different age levels. used a completely randomized design. 18 male turkeys, divided into 3 groups ages 8, 16, and 24 weeks, each group comprising 6 turkeys. The necropsied turkey's was taken histological preparations stained with haematoxylin-eosin (HE). results showed that picture layer levels...

The immunological performance of modern turkeys (one-third each of the Nicholas Turkey, British United Turkeys of America, and Hybrid Turkey strains) hatched in 2003 (2003 strain) was compared with that of a randombred control turkey strain (RBC2) established in calendar year 1966, when fed representative 1966 and 2003 type diets. The 2003 strain had a higher BW and bursa of Fabricius weight re...

The effects of vaccination on avian blood parameters are poorly understood. The present study was designed to evaluate whether different strains (Ulster 2C, B1, live LaSota and inactivated LaSota) of Newcastle disease vaccines had an effect on the haematological profile of female turkeys. Seventy-five female turkeys were allocated to treatment groups according to vaccination strain. All the bir...

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...
