Assessment of Blood Metabolites Disorders and Related Pathological Risk Factors in Cows of Constantine Region, Algeria

Abstract

The aim of the present study is to evaluate some blood metabolites and to predict the occurence of nutritional imbalances affecting milk production and health status of cows. It included 180 dairy cows of five different breeds reared in five farms of Constantine Governorate. The biochemical analyzes via Technicon RA-X and RA1000 autoanalyzers focused on: calcium, phosphorus, total proteins, lipids, glucose and creatinine.It results that hyperphosphatemia (> 65 mg/L) was clear in cows of farms 1 and 2 and moderate in those of farm 3; moderate hypocalcemia (< 97mg/L) in cows of farms 1, 2, 3 and 4; moderate hypoproteinemia (< 67 g/L) in farms 2 and 5; moderate hyperproteinemia (> 74.6 g/L) in farms 3 and 4, a clear hypercholesterolemia in whole farms. The significant differences (P< 0.01) via ANOVA test between farms, suggest variability of management methods, feeding practices and health status of cows.
