In October 1977, a study was undertaken to determine the role of bovine adenovirus type 3 in enzootic pneumonia of calves, and the efficacy of using a vaccine for prevention of disease. Bovine adenovirus type 3 was isolated from the herd under study in the previous year. Calves in the...
Bovine viral diarrhea virus (BVDV) is an enveloped, single-stranded positive-sense RNA virus. The BVDV genome is about 12.5 kb long and consists of a single open reading frame (ORF) flanked by untranslated regions at the 5' and 3' ends (5'-UTR and 3'- UTR, respectively). To investigate the role of cis-sequences...
Consumers' risk perceptions are examined to explain the underlying reasons for consumer
concern associated with milk from dairy herds treated with recombinant bovine growth
hormone (rbGH). A focus group study was employed as an initial step in exploring the
primary influences of consumer apprehension toward rbGH's use. The information
obtained...
A comparative study was made on the effect of urea denaturation
of bovine serum albumin (BSA), polyglycyl BSA and poly-L-phenylalanyl
BSA. The denaturation process was followed by ultraviolet
spectrophotometry and optical rotation.
A blue shift in the absorption maximum at 278 mμ was observed
in urea denatured proteins, In 7M...

The electrophoretic behavior of sarcoplasmic proteins was
investigated by the use of vertical acrylamide gel electrophoresis.
The first part of the study was concerned with the separation of
sarcoplasmic proteins extracted at different times of post-mortem
aging. Electrophoresis of the sarcoplasmic extracts by the discontinuous
technique, using ten percent acrylamide...
Fifteen adenoviruses from cattle, sheep, horses, and llamas were studied by virus neutralization to determine their degree of antigenic similarity. Prototype viruses included bovine adenoviruses species 1-8, ovine adenoviruses species 5 and 6, and equine adenovirus species 1. Unclassified viruses that were compared to the prototype viruses were isolated from...
