The pharmacokinetics of ceftiofur sodium were determined in domestic chicks, turkey poults, adult cockatiels (Nymphicus hollandicus), and adult orange-winged Amazon parrots (Amazona amazonica) after subcutaneous (chicks and turkey poults and intramuscular (i.m.) dosing (cockatiels and Amazon parrots). Turkey poult data were best fit to a single exponential model with disappearance half-lives (t...

The effects of feeding Fusarium moniliforme culture material, containing known concentrations of fumonisin Bj (FBi), were studied in turkey poults. Day-old poults were allotted randomly to dietary treatments containing 0, 0.41, 0.82, 1.23, 1.64, 2.87, 4.10, 5.33, 6.56, and 7.79% fumonisin culture material (FCM). These levels of FCM supplied 0, 25, 50, 75, 100, 175, 250, 325, 400, and 475 mg FBi...

This study was carried out to determine the effects of free choice feeding of starter feed and whole cereals on the growth of turkey poults. Two hundred-seventy poults (7-d old) were divided into 3 treatment groups each with 3 replications containing 15 males and 15 females. Control poults (C) were fed only on starter feed (280 g CP and 11.7 MJ ME/kg). Treatments for choice-fed turkey poults we...

The efficacy of the pleuromutilin derivative 81.723 hfu was tested in chicks and turkey poults by experimentally infecting them with Mycoplasma gallisepticum. The data were treated to obtain the mean effective doses, and these were compared to those obtained with tylosin tartrate. The compounds were administered either by ingluvial catheter or via the drinking water. Therapy was started on the ...

The current NRC selenium (Se) requirement for turkeys is 0.2 μg Se/g diet. We previously fed turkey poults a Se-deficient diet (0.005 μg Se/g) supplemented with 10 graded levels of Se (0, 0.025, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 0.75, 1.0 μg Se/g as Na2SeO3, 5/treatment) for 4 wk, and found that the minimum dietary Se requirement was 0.3 μg Se/g based on selenoprotein enzyme activity in blood, liv...

This trial examined the effect of 2 turkey breeder hen ages (33 or 55 wk of age) on performance, intestinal histology, and inflammatory immune response of female turkey poults grown to market weight. Using a randomized design, female poults were separated by breeder flock age (n = 8 floor pens/breeder flock age; n = 26 poults/pen; 0.195 m(2)/bird), fed identical commercial diets (9 phases), and...

objective:to show occurrence of cryptosporidiosis in native turkeys of lran by means of histopathological and parasitological methods. design:descriptive study.animals:fifty native turkey poults suffered from growth retardation,long standing diarrhea or both were obtained from native turkey raising areas of iran (northern and western provinces) procedure:the clinical signs and symptoms of poult...

This study was conducted to reexamine the hypothesis that human metapneumovirus (hMPV) will not infect turkeys. Six groups of 2-week-old turkeys (20 per group) were inoculated oculonasally with 1 of the following: noninfected cell suspension; hMPV genotype A1, A2, B1, or B2; or avian metapneumovirus (aMPV) subtype C. Poults inoculated with hMPV showed nasal discharge days 4-9 postexposure. Spec...

Data were collected on the down color of 1,386 parthenogenetic embryos and poults from eggs of 306 young virgin and older nonmated bronze turkey hens. Each hen involved was heterozygous (Cc) for alleles which affect feather pigmentation. Six hundred and sixty nine white and 717 colored parthenogenetic embryos and poults were observed, a 1:1 ratio. Subsequently, 89 of these 306 heterozygous bron...

A primary infection of 12.5 x 10(3) oocysts of Eimeria adenoeides , given to 20-d-old turkey poults, resulted in depression of weight gain, and the production of large numbers of oocysts in the feces, compared with uninfected controls. Poults were raised under conditions to prevent possible reinfection to determine the ability of the primary infection to confer protective immunity against a cha...
