An avian influenza virus (AIV), A/turkey/Israel/09 subtype H6N1, was isolated from turkey poults exhibiting typical pathology associated with AIV infection. The virus was characterized by RT-PCR using AIV subtype-specific primers and by the haemagglutination inhibition test using AIV subtype-specific antisera. The virus has an intravenous pathogenicity index of 0 and possessed a nucleotide sequ...

In the present study, the amnion of turkey and chicken embryos were injected 3 d prior to hatch with different levels of vitamin E (VE). In Experiments 1 and 2, turkey embryos received 10, 20, and 30 IU of VE. In Experiment 3, broiler embryos received 10 IU VE. In all three experiments, sham-injected control embryos (0 IU VE) received 300 microL of saline. In Experiments 1 and 2 (turkey embryos...

A feeding trial was conducted to investigate the efficacy of Pediococcus acidlactici (Bactocell®) or Baccillus cereus (Toyocerin®)-based probiotics on turkey’s performance, carcass yield, blood parameters and intestinal morphology. A total of 240 1- day-old male Nicholas turkey poults were allocated into three dietary groups with four replicates. A corn-soybean-based diet was used as a basal di...

Responses to stunting syndrome (SS) infective material obtained from affected broilers and administered per os were monitored for 3 wk in a fast-growing commercial broiler population, in slow-growing Leghorn chicks, and in turkey poults. At 2 and 3 wk, the size of the gastrointestinal tract (GIT) segments, the pH of the GIT contents, and the activities of digestive enzymes in the intestinal con...

The stress responses of mice and rats has been shown to be permanently altered by brief, gentle handling during the first 10 d of life, resulting in increased BW and resistance to stress-induced immunosuppression. The purpose of this study was to determine whether early handling of turkey poults could permanently affect production values and physiology of adult turkeys. Turkey poults were handl...

Tissue-specific accumulation of tocopherols and tocotrienols in turkey tissues during embryonic development and their susceptibility to lipid peroxidation were investigated. Fertile turkey eggs were incubated using standard commercial conditions. Embryonic tissues were collected at 16, 22, 25 d of incubation and from day-old poults (referred to as day 29) and alpha-; beta- + gamma- and delta-to...
