[Investigations on manifestations of vitamin E and selenium deficiency in sheep and goats].
In a prospective study from 1991-1998 plasma concentrations of alpha-Tocopherole (VitE) and Selenium (Se) were analysed in 125 sheep and 32 goats with generalised motor disturbances or elevated plasma-activities of Creatine-Kinase (CK). VitE-values < 1.0 mg/l and Se-values < 0.08 mg/l were regarded as deficiency. Diagnosis of pathological manifestations was based on blood enzyme values. CK-values in plasma > 300 U/l or Aspatate-Amino-Transferase (ASAT) > 150 U/l were regarded as myopathy, Glutamat-Dehydrogenase-values > 25 U/l indicated a hepatopathy. 92 (74%) sheep and 10 (31%) goats showed VitE and/or Se deficiency. There were no principal differences in the frequencies of myopathies (67%) and hepatopathies (46%) between pure VitE deficiencies or pure Se deficiencies or combinations of both deficiencies. In VitE deficiency and in the combinations of VitE and Se deficiency the elevations of the enzyme activities were more pronounced than in Se deficiency. The lethality was significantly higher in combined VitE + Se deficiencies (73%) than in pure VitE or Se deficiencies (35%). Combined VitE + Se deficiencies occurred more frequent in lambs (53%) and was often accompanied by anaemia (29%) and hypoproteinaemia (32%). The diagnostic reliability of ASAT and GLDH for the detection of VitE and Se deficiency was better than CK. Diagnostic and therapeutic strategies in flock diseases are discussed.
