Wildfire Response in Range Cattle.

The manner in which the producers and communities affected by the Starbuck fire dealt with the aftermath and recovery is the focus of this article. Ranchers, as stewards of the cattle, had to assess and attend to the welfare of survivors, euthanize the severally damaged, dispose of the dead, and deal with inadequate federal assistance and insurance claims. Veterinarians acted as coordinators of the community relief effort and supported the ranchers.

Twenty-four hour Holter monitoring in finishing cattle housed outdoors.

Introduction: Atrial premature complexes have been reported to be the most common arrhythmia in cattle and is suspected to be secondary to systemic disease, especially gastrointestinal disease. In order to properly identify pathologic arrhythmia in cattle, the normal rhythm and arrhythmia prevalence should be defined. The objective of this study was to determine the normal heart rate, rhythm, number of ventricular premature complexes (VPCs), and atrial premature complexes (APCs) in unrestrained Angus steers.

Effect of ractopamine hydrochloride and zilpaterol hydrochloride on cardiac electrophysiologic and hematologic variables in finishing steers.

OBJECTIVE To investigate the effects of dietary supplementation with the β-adrenoceptor agonists ractopamine hydrochloride and zilpaterol hydrochloride on ECG and clinicopathologic variables of finishing beef steers. DESIGN Randomized controlled trial. ANIMALS 30 Angus steers.

Cattle handling technique can induce fatigued cattle syndrome in cattle not fed a beta adrenergic agonist.

Angus crossbred steers (n = 40; 563 ± 44 kg) were used to examine the effects of handling method and fat thickness on the blood chemistry and physiology of market steers. Steers were blocked by backfat (BF) thickness and were randomly assigned to treatment groups: low-stress handling (LSH) and aggressive handling (AH). Cattle were then ran¬domly assigned to one of 5 blocks containing 4 steers from the LSH and AH treatments.

Animal Health Equipment Management.

Proper health equipment management requires significant attention to detail. Establishing and following protocols during processing (eg, cleaning and disinfecting equipment at the end of the work day) is required to ensure a safe product that is free of defects and residues. Overall cleanliness of equipment and facilities is important not only from a food safety standpoint but many view these as an overall indicator of attention to detail in the entire production system.
