Clinical Puerperal Paresis and Hypocalcaemia in Cattle A Statistical and Genetic Investigation

Abstract: Puerperal paresis in dairy cows has been and still is the subject of intensive research. Investigations are mainly concerned with the clinical picture, aetiology and pathogenesis of the disease. Only in a few instances does the material permit a statistical study of variations in the manifestation of the disease and the cause of such variations. A few investigations of this kind do exist however. JONSSON (1960) studied the influence of year, age, season, production capacity and other factors on the incidence o… Show more

“…The results would indicate a stronger genetic regulation of Ca and Mg levels in the serum during early pregnancy than at calving, Heritability was of the same order of magnitude as for puerperal paresis (DYRENDAHL et al, 1972) and was also comparable with that for the concentration of Ca in the blood of ewes (WIENER and FIELD, 1971).…”

“…The incidence found by us in the total material is, however, quite close to that in most other non-selected materials. Thus, RASBECH (1967) found 6.7 per cent in Denmark, BRANDS (1966) EKESBO (1966) found 8.6 per cent in a material without breakdown by breeds. A distinct difference between breeds was found in the incidence of retentio secundinarum.…”

“…The 2.00 test level may be useful for verifying the presence of hypocalcaemia. The combating of milk fever by breeding measures should entail, inter alia, that cows with this disease are prevented from mothering bulls ( DYRENDAHL et al, 1972). The test can then be used to avoid disqualification of cows through wrong diagnosis.…”
