Undergraduate student attitudes to current poultry industry issues over four semesters: surveying an introductory poultry science course

Abstract

Individual background and demographics affect student perceptions of animal production. Understanding how science-based education alters these opinions is a critical aspect of improving university instruction as well as increasing consumer engagement in the poultry industry. The study objectives were to quantify the effects of student background, career interests, and science-based instruction on opinions regarding current issues in the poultry industry. Undergraduate students enrolled in a one semester poultry science course at Iowa State University between 2018 and 2021 were anonymously surveyed at the start and end of the semester as part of a 4-yr study. Students who opted to take the survey answered three demographic questions indicating their 1) livestock experience, 2) sex, and 3) career goals. The body of the survey consisted of 16 "poultry issue statements" where students were directed to mark a vertical dash on a 130 mm horizontal line indicating their level of agreement with each statement. Post-survey collection, the line was separated into 5 sections for discussion: responses within 0%-20% indicated strongly disagree, 21%-40% disagree, 41%-60% neutral, 61%-80% agree, and 81%-100% indicated strongly agree. Responses were analyzed using Proc Mixed in SAS Version 9.4 with a Tukey-Kramer adjustment for all pairwise comparisons using main effects including demographic categories, education (pre- or post-instruction), and year the survey was taken. Responses to various issue statements were affected by students' livestock experience (P < 0.05; 6 out of 16 statements affected), sex (P < 0.05; 5 out of 16 statements), and ultimate career goals (P < 0.05; 4 out of 16 statements). Pre- vs. post-education responses differed significantly in 6 out of 16 statements (P < 0.05), and in 2 out of 16 poultry issue statements, the year of instruction affected student response (P < 0.05). These data indicate that individual student background, sex, and differing career interests impact opinions of current topics in the broiler and layer industries. Further, science-based education as well as the year the course was taken over consecutive semesters significantly altered student opinions.
