Introduction
Competency in bovine castration is expected of entry-level veterinarians
Simulation-based practice before performing a skill on a live animal can improve the student’s level of proficiency, facilitate skills assessment, and protect animal welfare by reducing surgical complications.

Comparison of Student Learning Outcomes
P = 0.005

Hypotheses
A model could be developed that would be acceptable to experienced clinicians
Model-trained students would achieve higher performance scores when castrating their first live bull calf
P = 0.12
Methods
Model development by LMU CVM food animal faculty
Veterinarian & student evaluation of model
Student opinion after using model and performing live surgery
Comparison of student learning outcomes
Third year veterinary students randomized to perform live surgery on bull calves before or after using model
Performance scores on live surgery from videos by blinded investigator
Rubric
Surgical time
Number of times instructor physically assisted student during surgery
Conclusions
The surgical bovine castration model was considered useful by veterinarians and veterinary students to learn how to castrate a live bull calf. Students’ performance scores after model training were higher than students’ scores after traditional training, suggesting that model training was beneficial. These data provide evidence for validation of the model..
