Hypoglycin A absorption in sheep without concurrent clinical or biochemical evidence of disease.

Background: Hypoglycin A (HGA) intoxication after ingestion of Acer spp. tree material has never been confirmed in domesticated ruminants despite their similar grazing habitats.

Objectives: To investigate whether sheep have low HGA bioavailability caused by rumen HGA breakdown.

Ultrasonographic scoring system for superficial digital flexor tendon injuries in horses: intra- and inter-rater variability.

Superficial digital flexor tendon (SDFT) tendinopathy is an important musculoskeletal problem in horses. The study objective was to validate an ultrasonographic scoring system for SDFT injuries. Ultrasonographic images from 14 Thoroughbred racehorses with SDFT lesions (seven core; seven diffuse) and two controls were blindly assessed by five clinicians on two occasions.
