INDEXES OF BIOCHEMICAL STATUS IN BLV INFECTED AND INTACT AYRSHIRE COWS

Abstract

To have a more comprehensive and deeper insight into pathogenic characteristics of BLV infection and leucosis progress in cattle the attention should be paid to a series of exogenic factors. Age, breed, productivity, housing technology, nutrition type, animal zoning are referred to the facts involved. In this respect it is urgent to conduct targeted examination of biochemical status in Ayrshire cows that, regarding the leucosis (BLV) infection, were zoned in the conditions of Krasnodar region. There were arranged 4 groups of animals, bovine leucosis virus infected and intact. Considerable quantitative differences were identified in the content of serum protein, calcium, urine, alpha-amilase, lactate dehydrogenase (LDH), magnesium, aspartate aminotransferase (AST), cholesterol, creatinine and copper in connection with BLV compromised animals. Comparative biochemical changes were shown in the imported cattle in the period of adaptation to new habitat conditions.
