Abstract

The authors have evaluated the efficacy of the colostrum supply in a commercial dairy herd. Newborn calves (n = 115) were sampled between the 1st and 7th day of life. The blood samples were measured with a cow-side test MBC QTII™ (Midland BioProducts Corporation, Boone, Iowa, USA), which measures the immunoglobulin level by radial immunodiffusion. Beside it the Na-sulphite precipitation test was also evaluated and the serum total protein concentration was also determined. The quick test resulted with the best accuracy, 86% of the animals were judged to have excellent IgG concentrations, namely colostrum supply. The Na-sulphite precipitation test and the total protein measurement showed that 66.9% and 78.3% of the newborn calves had adequate colostrum supply, respectively. The calves were followed up until weaning. Clinical diseases and mortality data were recorded. Until weaning 6 calves died (5.2%), all of them were subject of a pathological examination in the authors' diagnostic laboratory. The diagnoses were pyelonephritis and urocystitis, developmental disorder of the heart, colibacillosis and heart muscle fibrosis, and in 3 cases colibacillosis. Diarrhoea was the most commonly recorded disease with clinical manifestation, which was most commonly manifested between days 6 and 15 of age. There was higher mortality in those animals, where calving assistance was not needed at birth which confirms the primary role of colostrum supply immediately after calving and hygienic circumstances of hutches and providing milk replacement.
