Fifty-three free-ranging moose (Alces americanus) cows were darted from a helicopter with 3-4 ml of a premix combination of butorphanol (27.3 mg/ml), azaperone (9.1 mg/ml), and medetomidine (10.9 mg/ml; BAM), equivalent to estimated dosages of: butorphanol 0.26 ± 0.08 (mean 6 SD) mg/kg, azaperone...

The successful cardiopulmonary resuscitation of a hypoxic, unconscious and apnoeic fetus born to a cow having dystocia and placenta praevia in Rajasthan, India, [date not given] is described.

The goal of this study was to develop a method for the diagnosis of latent respiratory failure in calves with bovine respiratory disease (BRD) in farm conditions. The study involved 48 calves of the red-motley Holstein breed aged 14-28 days, with no previously experienced BRD, no dyspnea at rest,...

The aim of this study was to evaluate pulmonary dysfunction induced by experimental infection with Parachlamydia acanthamoebae in calves. Intrabronchial inoculation with P. acanthamoebae was performed in 31 calves aged 2-3 months old at two different challenge doses of 10⁸ and 10¹⁰...

A total of 42 male Holstein-Friesian calves, 3-7 weeks old, were used in the study to develop a bovine model for respiratory Parachlamydia acanthamoebae infection, and to determine the pneumopathogenic potential and physiopathology of P. acanthamoebae respiratory infection. The calves were divided...

The respiratory pathogen Chlamydia psittaci naturally occurs in bovine herds and was recently shown to impair calf health in a dose-dependent manner. The aim of this study was to determine whether the functional consequences and immunological reactions of infection were dose related by quantifying...

A 15-month-old Japanese Black steer with severe growth insufficiency died after a six-month follow-up following its diagnosis with polycythemia. The red blood cell count had remained high during the follow-up. At necropsy, a thickened right ventricular wall and ventricular septal defect of the...

AIM: To determine the physiological status of calves at birth and the perinatal factors that might predispose newborn calves to debility and death, using criteria previously established for newborn lambs. METHODS: Friesian mixed-aged cows and heifers on a dairy farm in New Zealand that were close...

Objective: This study was conducted to determine the macroscopic and histopathological lesions of a rotated uterus in cattle at the time of surgical treatment. Material and methods: The uterus of 54 cows with surgically treated uterine torsion intrapartum were observed and recorded....

Objective: Hypoxaemia accompanies dorsal recumbency in the horse and frequently complicates general anaesthesia. The physiology associated with this phenomenon is poorly understood. One possible cause of poor tolerance to dorsal recumbency is an absent or reduced response to hypoxic pulmonary...
