: The study was approved by the Danish Animal Experiments Inspectorate under the Danish Veterinary and Food Administration (Approval No. 2021-15-0201-01099).
: Data on %Brix from nine herds including 77 heifer calves were used to assess immunisation status (Otten ND, Skarbye AP, Krogh MA, Michelsen AM, Nielsen LR. Monitoring bovine dairy calf health and related risk factors in the first three months of rearing. Acta Vet Scand. 2023;65:45. ). In addition, data on IgG and %Brix from the same nine herds were published in a master’s thesis where an additional 13 herds were included (Wilm J. Association between serum IgG Level and clinical signs of gastrointestinal disease in newborn Danish dairy calves. Master’s thesis. University of Copenhagen. 2019).
