Abstract

South Dakota State University has developed a hands-on program that addresses the preharvest management factors that influence beef carcass value to aid producers in their management and marketing decisions. The 3-d program includes live cattle and carcass evaluation, beef carcass fabrication, a harvest demonstration, sensory panel, and presentations on topics including live market cattle evaluation, health, and disposition in relation to carcass quality, feeding and management, and value-added beef cuts. To evaluate program effectiveness, data were collected from all programs held between 2013 and 2019. Participants were asked to evaluate their perceived value for each program component, as well as their knowledge of the industry prior to and after completing the program. Upon completion of the 2018 Beef 2020, a focus group of program alumni was assembled to better understand participant experiences, application of the material, and guide future programming. The recommendations of the focus group were implemented during the 2019 program. Component value scores are reported in a box and whisker plot and participant knowledge was evaluated using a paired -test with significance determined at < 0.05. Special attention was given to the results of 2019 compared to previous years to determine the efficacy of the program changes. Overall, the average value scores for the sessions all ranked above 8 on a scale of 1-10, indicating a relatively large value to participants. Knowledge of carcass traits, carcass value, and management factors that influence those traits increased after participation in the Beef 2020 program (5.18 vs. 7.67 ± 0.16; < 0.0001). The use of a focus group was concluded to be an effective means of assessing program value, strengths, and weaknesses. The Beef 2020 program can be used as a model for other Extension professionals to create programs intended to link livestock producers to their end products.

摘要

南达科他州立大学开发了一个实践项目,该项目涉及影响牛肉胴体价值的收获前管理因素,以帮助生产者做出管理和营销决策。这个三维项目包括活牛和胴体评估、牛肉胴体分割、屠宰示范、感官小组,以及关于包括活牛市场评估、健康以及与胴体质量、饲养和管理以及增值牛肉切块相关的处置等主题的演讲。为了评估项目效果,收集了2013年至2019年期间举办的所有项目的数据。参与者被要求评估他们对每个项目组成部分的感知价值,以及他们在完成项目之前和之后对该行业的了解。在2018年“牛肉2020”项目结束后,召集了一组该项目的校友焦点小组,以更好地了解参与者的经历、材料的应用,并指导未来的项目规划。焦点小组的建议在2019年的项目中得到了实施。组成部分价值分数以箱线图形式报告,参与者的知识通过配对检验进行评估,显著性水平设定为<0.05。特别关注了2019年与前几年的结果,以确定项目变化的效果。总体而言,各场次的平均价值分数在1至10分的量表上均排名高于8分,表明对参与者有相对较大的价值。参与“牛肉2020”项目后,参与者对胴体特征、胴体价值以及影响这些特征的管理因素的了解有所增加(5.18对7.67±0.16;<0.0001)。得出结论,使用焦点小组是评估项目价值、优势和劣势的有效手段。“牛肉2020”项目可以作为其他推广专业人员创建旨在将牲畜生产者与他们的最终产品联系起来的项目的模型。
