Veterinary students require deliberate practice to reach competence in surgical bovine castration, but animal availability limits opportunities for practice. We sought to create and validate a surgical bovine castration model consisting of a molded silicone scrotum and testicles to allow students to practice this skill without the use of live animals. We sought to validate the model and associated scoring rubric for use in a veterinary clinical skills course. A convenience sample of third-year veterinary students ( = 19) who had never castrated a bovine were randomized into two groups. The traditionally trained (T) group performed castration on a live bull calf after a 50-minute instructional lecture. The model-trained (M) group received the same lecture and a 2-hour clinical skills session practicing bovine castration using the model. All students were subsequently digitally recorded while castrating a live bull calf. Performance recordings were scored by an investigator blinded to group. Survey data were collected from the students and from expert veterinarians testing the model ( = 8). Feedback from both groups was positive. The M group had higher performance scores than the T group (M group, = 80.6; T group, = 68.2; = .005). Reliability of rubric scores was adequate at .74. No difference was found in surgical time (M group, = 4.5 min; T group, = 5.5 min; = .12). Survey feedback indicated that experts and students considered the model useful. Model training improved students' performance scores and provided evidence for validation of the model and rubric.

The type species of DELTARETROVIRUS that causes a form of bovine lymphosarcoma (ENZOOTIC BOVINE LEUKOSIS) or persistent lymphocytosis.
Statistical formulations or analyses which, when applied to data and found to fit the data, are then used to verify the assumptions and parameters used in the analysis. Examples of statistical models are the linear model, binomial model, polynomial model, two-parameter model, etc.
A culture-specific acute delusional syndrome occurring mostly in the Malay people and Southern Chinese. The syndrome is characterized by the individual's sudden experience of depersonalization depicted by the belief that his penis is shrinking into his abdomen and that he will die when this occurs. Although generally classified as a culture-specific syndrome, koro may be no more than a variant of castration anxiety (ANXIETY, CASTRATION) as it has been described in non-Asian patients.
The type species of LENTIVIRUS, subgenus bovine lentiviruses (LENTIVIRUSES, BOVINE), found in cattle and causing lymphadenopathy, LYMPHOCYTOSIS, central nervous system lesions, progressive weakness, and emaciation. It has immunological cross-reactivity with other lentiviruses including HIV.
A species of PESTIVIRUS causing systemic infections including BOVINE VIRUS DIARRHEA-MUCOSAL DISEASE and BOVINE HEMORRHAGIC SYNDROME in cattle and some other cloven-hoofed animals. There are several strains and two biotypes: cytopathic (rare) and non-cytopathic. The severity of disease appears to be strain dependent. Cytopathogenic effects do not correlate with virulence as non-cytopathic BVDV-2 is associated only with Hemorrhagic Disease, Bovine.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
