Introduction According to the International Commission on Radiological Protection publication numbers 60 and 21, the environmental control standards should ensure human and other species protection to a desirable degree. Since application of radiographic procedures in Veterinary Medicine has increased significantly, in this study, we aimed to evaluate the entrance skin dose to the animals (e.g....

1. A two-host shared-macroparasite model was parameterized from the results of infection and transmission experiments, to investigate whether apparent competition between the ring-necked pheasant (Phasianus colchicus) and the grey partridge (Perdix perdix), mediated via the shared nematode Heterakis gallinarum, could theoretically cause partridge exclusion. 2. Both the model created and the exp...

Have you ever wondered how animals might respond to losing a member of their group? Many human activities, like hunting or changing the environment animals live in, can cause the loss of individual animals. However, how this loss affects the remaining animals in a group is still widely unknown. We wanted to investigate this question, so we tracked wild birds known as great tits. These birds for...

Evidence suggests that the transmission of shared parasites from ring-necked pheasants (Phasianus colchicus), specifically the caecal nematode Heterakis gallinarum, may be 1 cause of the decline of the gray partridge (Perdix perdix) in the United Kingdom (UK) over the past 50 years. It may be a factor preventing the recovery of the remaining wild gray partridge populations. Trials were undertak...

The problem of the formation leukemoid reactions in cattle is considered. It noted that such changes morphological composition blood are most often characterized by a decrease quantitative content lymphocytes while increasing concentration microphages (neutrophils). With elimination cause caused manifestation reaction blood, peripheral restored to normal.

Growth hormone (GH) has diverse functions in animals, together with other hormones from the somatotropic axis. Here, chicken GH (cGH) was investigated in recessive white chickens and Qingyuan partridge chickens as a candidate gene affecting egg production traits. Chicken egg production traits were studied in association with 4 selected single nucleotide polymorphisms (T185G, G662A, T3094C, and ...

Land-based birds, belonging to Galliformes order are considered to be potential intermediaries in the emergence of new strains of influenza A viruses (AIVs), but the viral circulation in these birds remains largely unknown. To gain insights into the circulation of AIV in the wild Galliformes populations in Italian Alps, we conducted a virological survey on rock partridge (Alectoris graeca saxat...

Sicily (Italy) hosts a "relict", endemic population of the birds Alectoris graeca whitakeri commonly known as Sicilian Rock Partridge. In last decades, due to risk restocking with other European and Asiatic species for hunting purpose, study was carried out investigate potential hybridisation. The mtDNA control-region nuclear microsatellites were genotyped. Due importance species, samples mainl...
