Prevalence and predictors of bacteremia in dairy calves with diarrhea.

Gastrointestinal disease is the most common cause of mortality in dairy calves. Septicemia is an important sequela of diarrhea, and the possibility of bacteremia is the primary justification for empirical antimicrobial therapy. Prior reports estimate that approximately one-third of diarrheic calves are bacteremic; however, those estimates may not be representative of routine cases in heifer calves on commercial dairy operations early in the course of disease.

Complications and outcomes of swine that underwent cesarean section for resolution of dystocia: 110 cases (2013-2018).

Objective: To report the surgical survival of dams and piglets and follow-up survival and future breeding potential of swine that underwent cesarean section for correction of dystocia.

Study Design: Retrospective study.

Animals: One hundred ten client-owned, female swine.

Closing wedge ostectomy with transfixation pin-cast stabilization for correction of angular limb deformities of the metatarsophalangeal region in four cattle.

Case Description: 4 calves were evaluated because of lameness and an angular limb deformity of the metatarsophalangeal region.

Clinical Findings: 3 calves (ages, 5 days, 10 days, and 1 month) had a congenital varus deformity of the metatarsophalangeal region characterized by medial subluxation of the first phalanx of digits 3 and 4 at the metatarsophalangeal joints. A 6-month-old heifer had a valgus deformity of the metatarsophalangeal region secondary to a malunion of a Salter-Harris type II fracture.

Investigation of a novel prosthesis technique for extracapsular stabilization of cranial cruciate ligament-deficient stifle joints in adult cattle.

Objective: To evaluate a novel prosthesis technique for extracapsular stabilization of cranial cruciate ligament (CCL)-deficient stifle joints in adult cattle.

Sample: 13 cadaveric bovine stifle joint specimens.

Procedures: In the first of 3 study phases, the most isometric points on the distal aspect of the femur (distal femur) and proximal aspect of the tibia (proximal tibia) were determined from measurements obtained from lateromedial radiographs of a stifle joint specimen maintained at angles of 135°, 90°, 65°, and 35°.

Peritoneal and scrotal carcinomas of unknown origin in two bovine calves.

Two unrelated bovine beef calves, aged 2 mo and 3 mo, were presented to The Ohio State University Veterinary Medical Center because of scrotal swelling and abdominal distension. On postmortem examination, there was abundant peritoneal fluid and numerous small friable masses covering all peritoneal surfaces and extending into the scrotum via the tunica vaginalis, with no identifiable primary neoplasm. Based on light microscopy, differential diagnoses included malignant mesothelioma and anaplastic carcinoma.

Safety and serologic response to a Haemonchus contortus vaccine in alpacas.

Haemonchosis in camelids remains a challenging disease to treat, and prevention has become increasingly problematic due to widespread anthelmintic resistance. Barbervaxis an adjuvanted vaccine containing natural H-11, H-gal-GP antigens obtained from Haemonchus contortus adults via a proprietary process and solubilized in Quil A. This vaccine is approved for use in Australia, after demonstrating its safety and efficacy in sheep and goats.
