Although farms are administered to high international standards, some reproduction problems, of uncertain aetiology, are encountered. The most frequently seen are conception failures, abortions, stillbirths and the birth of weak or malformed calves. These conditions are suggestive of bovine viral diarrhoea virus (BVDV) i...
متن کاملEffects of oral iron supplementation on haematocrit, live weight gain and health in neonatal dairy calves
Forty neonate calves were used in this study. The animals were divided into two treatment (n = 20) andcontrol (n = 20) groups. In the treatment group, oral iron as ferrous sulphate was supplemented to each calf atthe dose of 150 mg/day for 28 days, from the birthday. Blood sampling was taken from jugular veinimmediately after birth and on days 7, 14, 21 and 28 after birth. Significant differenc...
متن کاملIncrease in branched-chain amino acids due to acidemia in neonatal calves with diarrhoea
The aim of this study was to investigate the relationships between acid-base status and plasma branched-chain amino acids (BCAA) concentration in calves with diarrhoea for intravenous nutrition, especially with amino acid solution in calves with diarrhoea. Thirty-four Holstein calves aged 11.0±5.9 days old were enrolled in this study. In 10 of 34 calves exhibiting clinical signs of diarrhoea, s...
متن کاملComparison of bovine coronavirus isolates associated with neonatal calf diarrhoea and winter dysentery in adult dairy cattle in Québec.
Cytopathic coronaviruses were isolated in HRT-18 cells from bloody faecal samples collected from cows in Québec dairy herds having experienced typical outbreaks of winter dysentery (WD). The formation of polykaryons in the infected cell cultures was found to be dependent on the presence of trypsin in the medium. The WD isolates differed from the prototype Mebus strain of bovine enteropathogenic...
متن کاملTranscriptional changes detected in fecal RNA of neonatal dairy calves undergoing a mild diarrhea are associated with inflammatory biomarkers
After birth, a newborn calf has to adapt to an extrauterine life characterized by several physiological changes. In particular, maturation of the gastrointestinal tract in a new environment loaded with potential pathogens, which can predispose neonatal calves to develop diarrhea, and is a major cause of morbidity and mortality during the first 4 wks of life. We aimed to investigate the inflamma...
