Abstract
The analysis of serum mineral profile of cows before and after calving: A case study
Highlights
Focusing on high efficiency of dairy cows constantly deviates the parameters of the internal environment out of the optimal standard
3 Results and discussion Examination of blood serum from dry cows, at 4th week after drying, confirmed differences in calcium and phosphorus (Table 1), compared to reference interval published by Kahn (2005)
The average value for calcium was 2.11 mmol/l, which not reached the down value of reference interval of cows
Summary
Focusing on high efficiency of dairy cows constantly deviates the parameters of the internal environment out of the optimal standard. From the diagnosis point of view, individual disorders, clinical examination remains an important method in the conditions of field practice. This method is not sufficient for the overall etiopathological conclusion in production diseases. The metabolic profile test is an important diagnostic method for the detection of preclinical stages of metabolic disorders, especially in dairy farms (Kantíková and Balážik, 2003). The metabolic profile test provide the possibility to sensitively monitor changes in the internal environment of animals caused by various factors. Metabolic disorders can occur latently, especially in the initial period (Hofírek et al, 2009) They cause serious economic losses in productivity, worsen the feed efficiency, negatively affect the reproductive process and the viability of young animals. This study was aimed to describing the changes in the serum mineral profile during this period
