Research on the evolution of blood biochemical parameters in calves treated with phyto-therapeutic extracts

Respiratory disorders in calves are particularly important in veterinary pathology; the damage caused in the first three months of life is very high. The complex of respiratory diseases in calves, such as microbial, parasitic, as well as “a frigore”, evolves from simple rhino-laryngo-tracheitis to acute pulmonary thromboembolism.
The purpose of this paper is to study the effect of administration in feed ration of phyto-therapeutic products in calves with respiratory disease and their influence on some biochemical parameters and blood components. The research was conducted in a farm on a number of 21 calves Simmental breed with respiratory disease of different intensities, administering for 10 days the therapeutic purposes, alcoholic extract of Echinacea purpurea combined with Valeriana officinalis, dose of 20 ml/calf, morning and evening. In order to conduct laboratory tests, blood samples were collected from diseased calves before and after treatment determining the WBC counts, serum transaminases (ASAT, ALT), GGT, calcium, phosphorus and magnesium. Analyzing the results obtained after treatment conclude the following: calves in the study, both before and after treatment, presents medium condition of anaemia; in the case of leukocyte formula by administration of the phyto-therapeutic extract significantly increases the number of lymphocytes and neutrophils counts decreases; in severe cases, phyto-therapy is recommended associated with anti-infectives.
