This study compared the cholesterol levels and shell pigments (protoporphyrin biliverdin) of chicken (conventional organic), quail, pheasant, goose eggs. The material for was (organic system - Lohmann Brown conventional HyLine Brown) eggs, quail (Coturnix coturnix japonica), (local), pheasant (Phasianus colchicus) eggs homogeneously selected with a subjective scoring. High-performance liquid ch...

Knowledge of the ecology of the Eastern Encephalitis (EE) virus has accumulated rapidly since the agent was first isolated in 1933. The sporadic incidence of infections, lack of direct contact except among pheasants in the same pen, association of outbreaks with swampland areas, and the occurrence of infections following the peak of the mosquito season led to the theory that the virus was trans...

Many recently designated or expanded nature reserves in China were forest farms that ceased operations in the aftermath of the catastrophic Yangtze River floods of 1998. Although the vegetation in many of these areas has been altered significantly during forestry operations, there is now an opportunity to reduce, or even reverse, habitat loss for wildlife species that inhabit these forests. One...

The major histocompatibility complex (Mhc) of the ring-necked pheasant contains two polymorphic Mhc class II B genes. We show here, by screening of a cDNA library and RT-PCR from RNA, that both of these loci, Phco-DAB1 and Phco-DAB2, normally are transcribed in the spleen. They differ mainly in the 3' untranslated (UT) region, with the transcript lengths, not including the poly(A) tails, being ...

The life of game birds (pheasants) in nature is coupled with a number of difficulties in all seasons of the year. This refers to finding food, breeding, laying eggs, raising the young, fleeing from their natural enemies and lack of protection from unfavorable climatic conditions. The pheasants that live in captivity--aviaries for pheasants--do not have such difficulties--they are fed regularly ...

3H-labeled 35S RNA from avian myeloblastosis virus (AMV), Rous associated virus (RAV)-0, RAV-60, RAV-61, RAV-2, or B-77(w) was hybridized with an excess of cellular DNA from different avian species, i.e., normal or leukemic chickens, normal pheasants, turkeys, Japanese quails, or ducks. Approximately two to three copies of endogenous viral DNA were estimated to be present per diploid of normal ...
