Abstract: A system for evaluating lameness of animals is provided. In the system, one or more imaging devices are configured to capture a recording of an animal walking or standing from a profile view, an anterior view, or a posterior view. A computing device is in communication with the one or more imaging devices, and the computing device is configured to access an artificial intelligence model to analyze the recording to assign a lameness score to the animal. The computing device then outputs the lameness score to a user. In addition, pressure-sensing mats with force plates are configured to measure the leg weight bearing and total body weight of animals to track fluctuations in body weight and leg strength. Also disclosed are a method of identifying lameness in an animal and a mobile application that implements the method.

Abstract: Immunogenic compositions directed against C. jejuni, particularly hypervirulent strains thereof that are able to translocate the intestinal tract and cause systemic infection and abortion, are provided. Applicants have identified a novel major outer membrane protein and particularly a peptide portion thereof that is indicative of the recent hypervirulent strains and may be used in vaccine protocols and immunogenic and diagnostic compositions.
