Development of a novel clinical scoring system for on-farm diagnosis of bovine respiratory disease in pre-weaned dairy calves. [PDF]
Several clinical scoring systems for diagnosis of bovine respiratory disease (BRD) in calves have been proposed. However, such systems were based on subjective judgment, rather than statistical methods, to weight scores.

Protocol for a Scoping/Systematic Review: Scoping Review of Vaccination for the Prevention of Calf Scours in Cow-Calf Operations [PDF]
Background: The use of antimicrobials in the livestock industry has been a topic of increasing concern in the last few years. Calf scours is one of the main causes of mortality among calves younger than 1 month and affects the development of the animal,

Effect of bovine viral diarrhea virus in the feedlot [PDF]
It could be argued that bovine viral diarrhea virus (BVDV) is one of the most economically significant infectious pathogens of feedlot cattle. Although the direct economic losses caused by this virus have not been well quantified, the role it plays as an immunosuppressive agent and as a potentiator for other diseases, most notably bovine respiratory ...

Buoyant Density of Bovine Viral Diarrhea Virus
SummaryBovine viral diarrhea virus (BV DV), strain NADL, was purified by removing extracellular fluid from infected cultures at 96 hr postinoculation and clarifying by low speed centrifugation. Clarified fluid was concentrated by centrifugation onto a two-step 20-50% sucrose discontinuous gradient.

Serological response of the bovine fetus to bovine viral diarrhea virus [PDF]
Susceptible pregnant heifers were inoculated with bovine viral diarrhea virus at 150 days of gestation and earlier. Fetuses were surgically collected at selected times after inoculation. Serum immunoglobulins were quantitated, and the presence of specific antibodies was determined.

Segregation of Bovine Viral Diarrhea Virus into Genotypes
Isolates of bovine viral diarrhea virus (BVDV) were segregated into two groups based on comparison of sequences from the 5' untranslated region (UTR) of the viral genome. Phylogenic analysis suggested that these groups, termed BVDV I and BVDV II, are as different from each other as reference BVDV (BVDV-NADL, BVDV-SD-1, BVDV-Osloss) are from hog cholera
