Trichinella britovi as a risk factor for alternative pig production systems in Greece and Europe
Trichinellosis is an important zoonosis and the most common source of human infection is meat from pigs and wild boars. The European Union (EU) supports alternative pig production systems (organic and free-ranging) as sustainable farming systems. However, these systems that allow outdoor access for farm animals, may create new or reintroduce old risks to public health. During the last years, al...
متن کاملEffect of Varying Protein Levels and Preservation Methods and Duration on Egg Production Performance and External Egg Qualities of Japanese Quails in a Semi-Arid Environment
The study was conducted to determine the effect of varying protein levels and preservation method on external egg qualities of Japanese quails. A total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (CRD) replicated six times. A factorial arrangement of 3 × 4 × 4 which involves 3 protein levels (15, 20 and 25% crude protein), 4 storage method...
متن کاملRelationship between Prolactin Hormone Level, Molting and Duck Egg Production
The aims of this study were to obtain information on the mechanism of molting and the prolactin hormone levels affecting egg production. The study utilized AP (crossbred of Alabio ♂ with Peking ♀) and PA (crossbred of Peking ♂ and Alabio ♀ ducks) with a total of 180 birds. The observed variables were the duration of cessation of egg production before and after molting, the prolactin hormone lev...
متن کاملEvaluation of Homocysteine Level as a Risk Factor among Patients with Ischemic Stroke and Its Subtypes
Background: Epidemiological research has shown that increased total homocysteine (tHcy) levels are associated with an increased risk of thromboembolic disease; however, controversy still exists over which subtype of stroke is allied to hyperhomocysteinemia. This study aimed to investigate whether elevated tHcy is an independent risk factor for ischemic stroke and to compare tHcy levels in patie...
متن کاملA low-level jet in eastern Iran: a possible factor in dust events in the region
One of the world's major mineral dust source regions lies along the border between Iran and Afghanistan. In this studyit is hypothesized that a low-level jet may play in role in generating the intensity of this source region. The presence of alow-level jet east of the Seistan mountains is documented here for the first time. The jet exists mainly from May toSeptember and has a core at 850 mb. Ma...
