In this article, a simulation model for rectal palpation teaching in cows, Breed'n Betsy, is evaluated. Furthermore, the learning process of rectal palpation is depicted during a training period in live cows. In experiment 1, eight students were trained in live cows (group A) and nine students were trained using Breed'n Betsy (group B). After 25 palpations, their ability to localize and evaluate structures was evaluated in practical tests in live cows. Group A had higher results than group B (p<0.001) and were more skilled at localizing the uterus and localizing and evaluating the ovaries (p<0.05). Group B was better at pregnancy diagnosis (nonsignificant). Results suggest that Breed'n Betsy cannot fully replace training in live cows, but may be a valuable addition to the classical teaching method. Suggestions for future improvement are made. In experiment 2, 10 students were intensely trained in live cows throughout the year and evaluated in practical tests at three time points (September, January, and March). Results were analyzed as a function of time point and the category of experience (1: 0-50 cows; 2: 50-100 cows; 3: 100-150 cows; 4: 150-200 cows; 5: >200 cows). Results increased in time (p<0.05) and were higher in categories 3, 4, and 5 than in category 1 (p<0.05). Although all of the students in the higher categories successfully localized the cervix, uterus, and ovaries, they had difficulties in interpreting these structures, suggesting that palpation of 200 cows is insufficient to reach a consistent level of expertise.
在本文中，对用于奶牛直肠触诊教学的模拟模型“繁育贝齐”进行了评估。此外，还描述了在活牛训练期间直肠触诊的学习过程。在实验1中，8名学生在活牛身上接受训练（A组），9名学生使用“繁育贝齐”进行训练（B组）。在进行25次触诊后，通过对活牛的实际测试评估他们定位和评估结构的能力。A组的结果高于B组（p<0.001），并且在定位子宫以及定位和评估卵巢方面更熟练（p<0.05）。B组在妊娠诊断方面表现更好（无显著差异）。结果表明，“繁育贝齐”不能完全替代在活牛身上的训练，但可能是传统教学方法的一个有价值的补充。并提出了未来改进的建议。在实验2中，10名学生全年在活牛身上进行强化训练，并在三个时间点（9月、1月和3月）进行实际测试评估。结果作为时间点和经验类别（1：0 - 50头牛；2：50 - 100头牛；3：100 - 150头牛；4：150 - 200头牛；5：>200头牛）的函数进行分析。结果随时间增加（p<0.05），3、4和5类别的结果高于1类别（p<0.05）。尽管所有较高类别的学生都成功定位了子宫颈、子宫和卵巢，但他们在解释这些结构方面存在困难，这表明触诊200头牛不足以达到一致的专业水平。
