Variation in the Multivariate Relationships Between Serum Amyloid, Haptoglobin and Biochemical Profiles of Aborted and Non-Aborted Cows | Stephy Publishers
Archives of Dairy Research and Veterinary Science - (ADVS) | Stephy publishers Abstract: Because the time in which gestational loss or bovine abortion occurs is associated with multifactorial causes, the objective of this study was to assess multivariate relationships between the biochemical profile and acute phase proteins in aborted cows. We performed monitoring and monthly blood sampling during gestation in 140 dairy cows. A total of 18 cows aborted, which were considered ‘cases’; retrospectively, we used samples from 29 ‘control’ cows, which were taken at the same time. Thus, we compared multivariate relationships between the two groups, to evaluate variables potentially associated with cow abortion. We classified abortion as either infectious (due to DVB, leptospirosis or neosporosis) or non-infectious (protein or energetic imbalance evinced in metabolic profile). Of the 18 cows that aborted, there were 6 with evidence of positivity or seroconversion to the analysed diseases, 13...
