Borjúhasmenés, és ami a hátterében van - egy magyarországi tehenészetben

Abstract

An investigation was carried out at a large-scale dairy herd in Hungary to identify the important infectious agents playing a role in the frequently occuring (incidence approx 70- 75%) neonatal calf diarrhoea (NCD), focusing on routinely available and cost effective laboratory techniques.. Furthermore the major risk factors of NCD i.e. (1) colostrum quality in terms of its immunglobulin (Ig) level; (2) the colostrum intake by means of the estimated Ig level in the calves’serum measuring the serum total solids (STS) and (3) the environmental bacterial infection pressure at the surroundings of the newborn calves were evauated.
