Most research on heat stress has focused (sub)tropical climates. The effects of higher ambient temperatures the daily behavior dairy cows in a maritime and temperate climate are less studied. With this retrospective observational study, we address that gap by associating time budgets Netherlands with temperature temperature-humidity index (THI) variables. During period 4 years, 8 commercial farms were equipped neck leg sensors to collect data from 4,345 cow lactations regarding their budget....
(Sub)clinical hypocalcaemia occurs frequently in the dairy industry, and is one of earliest symptoms an impaired transition period. Calcium deficiency accompanied by changes cows' daily behavioural variables, which can be measured sensors. The goal this study was to construct a predictive model identify cows at risk using sensor data. For 133 primiparous 476 multiparous from 8 commercial Dutch farms were equipped with neck leg sensors measuring parameters, including eating, ruminating,...
Lameness, one of the most important disorders in dairy industry, is related to postpartum diseases and has an effect on cow welfare, leading changes cows' daily behavioral variables. This study quantified lameness time budget cows transition period. In total, 784 multiparous from 8 commercial Dutch farms were visually scored their locomotion (score 1–5) body condition 1–5). Each was early late dry period as well wk 4 postpartum. Cows with scores 1 2 grouped together nonlame, score 3...
Cows from 8 commercial Dutch dairy farms were equipped with 2 sensors to study their complete time budgets of eating, rumination, lying, standing and walking times as derived a neck leg sensor. Daily sensor data 1074 cows 3201 lactations was used 1 month prepartum until 10 months postpartum. Farms provided over 5 year period. The final models (lactational budget 24h budget) showed significant effects parity, farm calving season. When primiparous introduced in the lactational herd, they...
Abstract A 12‐day‐old, male Holstein Friesian calf was presented to the hospital due progressive ataxia and tremors since birth. diffuse central nervous system disorder primarily affecting white matter suspected based on clinical neurological examination. Blood tests were unremarkable, except for positive serology Schmallenberg virus. Magnetic resonance imaging of brain demonstrated severe, abnormalities regions encephalon cranial cervical spinal cord, consistent with...
We describe two clinical cases of diplomyelia with hydromyelia in newborn calves. Both animals presented signs a general proprioceptive ataxia affecting the pelvic limbs. The most clear finding during examination was an unilateral (case 1) or bilateral 2) absent patellar reflex. Only second case serologically tested positive for Schmallenberg virus, which is not very likely aetiology. cause spinal cord lesions both calves remains unknown.
Abstract Background This case report describes the clinical signs of a calf with focal diplomyelia at level fourth lumbar vertebra. Magnetic resonance imaging (MRI) images and histological findings affected spinal cord are included in this report. differs from previously reported cases terms localization minimal extent congenital anomaly, symptoms during further examinations. Case presentation The was presented to Farm Animal Health clinic, Faculty Veterinary Medicine, Utrecht University, an...
This case report describes the clinical signs, magnetic resonance imaging (MRI) findings and associated (histo)pathological in a crossbred Belgian Blue calf with congenital complex brain anomaly. The was presented non-progressive signs (including cerebellar ataxia) since it born, suggestive of multifocal intracranial lesion. A anomaly suspected after hematology, biochemistry, serology, cerebrospinal fluid analysis, study performed. following abnormalities were principal changes identified:...
This case report describes an 18‐day‐old female Holstein‐Friesian calf with congenital symmetrical lateralised nostrils and maxillary hypoplasia. The had problems the uptake of solid food inspiratory expiratory stridor. Further investigation showed that there was no palatoschisis, but a 1–2‐mm open duct found in rostral part hard palate. cranial palate made 90° angle caudal therefore shaped like T. Since around day 34 gestation nose placodes normally fuse, error most likely occurred close...
