Binocular vision disorders (BVD) are quite common in subjects with cerebellar dysfunctions. Also individuals with strabismus often suffer from many motor deficits, such as impaired body balance and walking. It is known that the cerebellum is necessary to maintain proper body posture but also to learn motor skills. It is conceivable that subjects with BVD would also have deficits in procedural (...

Bovine viral diarrhea (BVD) viruses are pestiviruses that have been isolated from domestic and wild ruminants. There is serologic evidence of pestiviral infection in more than 40 species of free-range and captive mammals. Vertical transmission can produce persistently infected animals that are immunotolerant to the infecting strain of Bovine viral diarrhea virus (BVDV) and shed virus throughout...

Pregnancy losses from fertilization to term are extensive in lactating dairy cattle. In many cases, they are underestimated because of the inability to determine conception early after insemination. For most producers, pregnancy losses are only quantified after the initial di‐ agnosis is performed at approximately 30 to 45 d of gestation. Recent studies that provid‐ ed reliable assessments of f...

Bovine viral diarrhoea virus (BVDV) is the most prevalent infectious disease of cattle. It causes financial losses from a variety of clinical manifestations and is the subject of a number of mitigation and eradication schemes around the world. The pathogenesis of BVDV infection is complex, with infection pre- and post-gestation leading to different outcomes. Infection of the dam during gestatio...

A class of high-order shock-capturing schemes, PnTm-BVD (Deng et al., 2019; Deng 2020) have been devised to solve the Euler equations with substantially reduced numerical dissipation, which enable high-resolution simulations resolve flow structures wider range scales. In such low errors round-off level might grow and contaminate solutions. typical example problems is loss symmetry in solutions ...

A programme to eradicate bovine viral diarrhoea was launched in Switzerland in 2008 with the aim of eradicating the causal virus. During the first year of the programme, the entire population of 1.6 million cattle were tested for the presence of the virus; in the following three years an additional 1.8 million calves were tested. The complexity of information generated during the eradication pr...
