Behavioral and Physiological Responses of Calves to Marshalling and Roping in a Simulated Rodeo Event.
Rodeos are public events at which stockpeople face tests of their ability to manage cattle and horses, some of which relate directly to rangeland cattle husbandry. One of these is calf roping, in which a calf released from a chute is pursued by a horse and rider, who lassoes, lifts and drops the calf to the ground and finally ties it around the legs. Measurements were made of behavior and stres...
متن کاملComparison of Thoracic Auscultation, Clinical Score, and Ultrasonography as Indicators of Bovine Respiratory Disease in Preweaned Dairy Calves
BACKGROUND The diagnostic tools for bovine respiratory disease diagnosis include clinical inspection, thoracic auscultation, and ultrasonography. HYPOTHESIS Thoracic auscultation and clinical examination have limitations in the detection of lung consolidation in dairy calves. ANIMALS Prospective cohort of 106 preweaned calves from 13 different dairy herds (10 with a history of active bovine...
متن کاملBehavioral Intrusion Detection Indicators
Monitoring and analysing Information system(IS)’s security events has become more and more difficult in the last few years. As IS complexity rises, the number of mandatory monitoring points has increased along with the number of deployed probes. Consequently, a huge amount of information is reported to the analyst which subsequently floods him and implies the implementation of very complex even...
متن کاملOpioid peptides and behavioral and physiological responses of dairy cows to social isolation in unfamiliar surroundings.
To test whether endogenous opioid peptides are involved in the behavioral and physiological responses of cattle to stress, 12 Holstein cows were either placed in social isolation in unfamiliar surroundings for 15 min or remained in their home stalls, either with or without naloxone treatment, following a Latin square design. Vocalizations (judged as high or low frequency), defecation/urination,...
متن کاملDetection of Bovine Coronavirus in Healthy and Diarrheic Dairy Calves
BACKGROUND BCoV is identified in both healthy and diarrheic calves, complicating its assessment as a primary pathogen. OBJECTIVES To investigate the detection rates of bovine coronavirus (BCoV) in feces of healthy and diarrheic calves and to describe the usefulness of a pancoronavirus reverse transcriptase (RT) PCR (PanCoV-RT-PCR) assay to identify BCoV in samples of diarrheic calves. ANIMA...
