Excitable cattle are dangerous to personnel and have reduced individual performance. The aim of this study was to 1) identify objective criteria for evaluating bull temperament and 2) examine relationships among temperament, behavior, and performance of bulls during an 84-d performance test. Angus bulls ( = 60) were reared in 6 pens based on BW and age. Pen scores (PS; 1 = docile and 5 = very a...

To effectively select for temperament, selection criteria must reflect an animal's response to stress. Subjective measures such as chute (CS) and exit (ES) score provide fast easy assessments of temperament but may be subject observer bias inconsistency. Objective cortisol other metabolites have been associated with increased stress in cattle, especially regarding transportation. Our objectives...

Chaque année, 90 000 personnes âgées de 65 ans ou plus se blessent lors d’une chute. Le portail en ligne bpa.ch/parachutes du Bureau prévention des accidents (BPA) met à disposition tous les outils et connaissances nécessaires pour permettre aux spécialistes prévenir chutes. Cela vient soutenir la mise œuvre réussie l’indicateur qualité recommandé par SSMIG «Identification risques chutes préven...

Observations were collected for the purpose of comparing exit velocity measurements in the form of exit score (ES; walk, trot, canter, or run) and flight speed (FS) as assessments of cattle temperament. Squeeze chute exit velocity was obtained for 1,181 crossbred yearling steers using ES and FS temperament systems. Flight speed used infrared sensors to determine the time taken for an animal to ...

The objectives of this study were to evaluate the effects of castration method (banding vs. surgical) and use of analgesia on behavior and feedlot performance in cull bulls. Angus, Hereford, and Angus-crossbred bulls (n = 20; initial BW = 384 ± 59.3 kg; 336 ± 20.1 d old) were housed in feedlot pens equipped with the ability to measure individual daily feed intake. A balanced randomized block de...

Epidemiological studies can be used to identify risk factors for livestock welfare concerns but have not been conducted in the cow-calf sector for this purpose. The objectives of this study were to investigate the relationships of 1) herd-level management, facilities, and producer perspectives with cattle health and behavior and stockperson handling and 2) stockperson handling on cattle behavio...
