Footrot, including interdigital dermatitis, is caused by Dichelobacter nodosus cause the majority of lameness in sheep in the UK. Lame sheep often have overgrown hoof horn but recent evidence has indicated that trimming overgrown hoof horn increases recovery time, and that routine foot trimming of the flock does not reduce the prevalence or incidence of lameness. The objectives of this study were to investigate the temporal associations between hoof horn length, footrot and climate. Fifty multiparous ewes were monitored for 10 months.

Lameness scoring (0–3) was carried out on four UK dairy farms during the housing period over three consecutive years (2010–2012). At the start of the study cows were matched by parity and stage of lactation and randomly allocated into a treatment (TX) and a control (CX) group. Cows were enrolled when two sound scores (0 or 1) were followed by a lame score (2). Farmers were immediately notified of score 3 cows, which were then excluded from the study, irrespective of whether they were in treatment or control groups.

In order to investigate sheep sources of Streptococcus dysgalactiae in flocks affected with joint ill, 10 sheep flocks in England and Wales with laboratory-confirmed cases of infectious arthritis (joint ill) caused by S dysgalactiae were visited during a disease outbreak while a further four flocks were visited during the lambing period in the year following an outbreak. A total of 5239 samples were collected for bacterial culture from 797 ewes and their 1314 lambs.

Lameness is a significant welfare and economic issue in all dairy systems. However, there is only a limited amount of published data on the incidence and prevalence of lameness in the pasture-based systems used in New Zealand. One key area where knowledge is lacking is how well farmer perception of lameness matches that identified by more objective locomotion scoring. Previous studies of this topic have focussed on housed cows.

This study aimed to describe a suitable acoustic window to facilitate access to the sciatic and femoral nerves in calves and to study the effects of their blockade with local anaesthetics. The neuroanatomical and ultrasound (US) study was performed on the cadavers of 10 calves, and the effects of 2% lidocaine with epinephrine (0.2 mL/kg) were determined in five healthy calves.

A high percentage of osteoarthritis (OA)-like patellar groove lesions in the stifle joint in calcium-deficient bulls has been recently reported. The prevalence of these lesions in bulls deficient in or supplemented with calcium was compared to findings in culled and healthy bulls to determine whether they represent normal anatomical variations, developmental anomalies or OA. It was hypothesized that the patellar groove lesions may represent OA. Distal cartilage samples from 160 femurs were analysed using a macroscopic Société Française d’Arthroscopie (SFA) OA grading system.

Objective: The aim of this study was to establish normal reference values of the forelimb and hindlimb joint angles in normal Holstein calves. Methods: Thirty clinically normal Holstein calves that were free of any detectable musculoskeletal abnormalities were included in the study. A standard transparent plastic goniometer was used to measure maximum flexion, maximum extension, and range-of-motion of the shoulder, elbow, carpal, hip, stifle, and tarsal joints. The goniometric measurements were done on awake calves that were positioned in lateral recumbency.

The aim of this research was to investigate the correlation between the thickness of solar soft tissue (SST; i.e. the corium and subcutaneous tissue) in early lactation and sole ulcer formation in late lactation. Fifty Holstein–Friesian cows were examined three times: (1) 30 days after calving (locomotion scoring, trimming, claw examination, measurement of SST); (2) 70 days after calving (locomotion scoring); and (3) 180 days after calving (locomotion scoring, trimming, claw examination).
