Jurajdova J.: Levels of Minerals in Sera of Chickens Suffering from Marek's Disease. Acta vet. Brno, 47, 1978: 189-196. The concentrations were studied of sodium, potassium, calcium, magnesium and phosphorus as well as the correlations and coefficients of their level ratios in sera of RIR chickens 56 days after infection with Marek's disease virus, and they were compared with the controls. In t...

The objectives of this study were to investigate the immune responses of broiler chickens fed diets supplemented with different level of chromium methionine (CrMet) in heat stress (HS) condition. Two hundred and eighty eight male broiler chickens (Ross 308) were allocated to four treatment groups (supplementation with 0, 200, 400 or 800 ppb Cr in the form of CrMet) in a completely randomized de...

The effect of vitamin A deficiency or the lentogenic La Sota strain of Newcastle disease virus (NDV) infection, or both, on immunoglobulin (IgA and IgM) levels in bile and plasma were investigated. In addition, tissue distribution of IgA-, IgG- and IgM-containing cells was studied to establish the source of these Ig. Chickens (1-d-old) with limited vitamin A reserves were fed ad lib. on diets c...

The chickens of local rocks breed were grown in the vivarium Institute Zoology up to 20 days age. Chickens fed with standard bird combined feed for broilers. For studying dynamics hematological parameters blood pockmarked infected E.tenella and treated Artemisia absinthium divided into three groups birds each. first group not (control). second third dose 20,000 sporulated oocysts. was (control ...

Objective: Rice Bran Oil (RBO) is extracted from the outer layer of rice. Little information is available regarding its safety. The present study was conducted to assess its safety in chicken embryo model. Materials and Methods: RBO was injected on day 4 of incubation of chickens. The tissues and serum samples were collected. Oxidative stress parameters in the liver, kidney and brain and bioche...

Populations of the lesser prairie-chicken (Tympanuchus pallidicinctus), an endemic grouse of the south-central United States, have declined precipitously. This species occurs in shortand mixed-grass prairies with sandy soils. Apart from perennial grasses of short stature, prairie-chicken habitat is characterized by dryland shrubs of the sand shinnery community, particularly the shinnery oak (Qu...

Germ cell differentiation in reverse-sexed reproductive organs and interspecies germ line chimeras provides insight into the mechanism of germ cell development and represents a useful tool for conservation of endangered birds. We investigated the migration and survival capacity of male chicken primordial germ cells (PGCs) in female chicken embryos and in quail and Korean ring-necked pheasant em...
