Abstract

Students who major in animal science at U.S. institutions are generally exposed to a curriculum that emphasizes commercial, large-scale production of the few traditional food animals: cattle, poultry, sheep, and swine. Globally, most farmers live in lesser-developed countries under limited-resource conditions of land, feed supplies, equipment, and capital. The promotion of commercial animal production enterprises may not be appropriate for such farms because it can subject farmers to considerable economic risk. Rather, use of limited numbers of large livestock, locally adapted breeds, or smaller livestock (e.g., ducks, goats, guinea pigs, and rabbits) may be more appropriate under subsistence, integrated farming systems. In this global context, a course in international animal agriculture has been taught for 15 yr to undergraduate and graduate students. The course consists of a review of traditional and potential livestock species well suited for impoverished families on small farms and methods to implement sustainable livestock projects, including feasibility, design, implementation, monitoring, and evaluation stages. To enhance student understanding, global food issues and challenges are illustrated with case studies. A term paper is also assigned for which students choose three suitable livestock species or local breeds that would be complementary on a small crop farm (< 5 ha). Daily dietary requirements of protein and energy per family member are calculated. Itemized enterprise budgets and production tables are prepared. Early in the course, the general consensus of students was that people who are malnourished and live in poverty have low personal ambition and motivation, and that their problems should be amenable to solution by application of American technology and expertise. The course modifies such attitudes and enhances a student's critical thinking and problem-solving abilities and communication skills. Course evaluations indicated that students believed that it is important to acquire some international knowledge and understanding when seeking a job, and that certain animal science courses should contain some international content. Students gain an understanding of global animal agriculture and an appreciation of the complexity of food production and hunger issues.

摘要

在美国院校主修动物科学的学生,通常接触到的课程强调少数几种传统食用动物的商业化大规模生产,即牛、家禽、绵羊和猪。在全球范围内,大多数农民生活在欠发达国家,面临着土地、饲料供应、设备和资金等资源有限的状况。推广商业化动物生产企业可能并不适合这类农场,因为这会让农民承受相当大的经济风险。相反,在自给自足的综合养殖系统下,使用数量有限的大型家畜、当地适应品种或小型家畜(如鸭、山羊、豚鼠和兔子)可能更为合适。在这种全球背景下,一门国际动物农业课程已面向本科生和研究生讲授了15年。该课程包括对非常适合小农场贫困家庭的传统和潜在家畜品种的回顾,以及实施可持续家畜项目的方法,包括可行性、设计、实施、监测和评估阶段。为增强学生的理解,通过案例研究来说明全球粮食问题和挑战。还布置了一篇学期论文,让学生选择三种适合在小型作物农场(<5公顷)互补的家畜品种或当地品种。计算每个家庭成员每天的蛋白质和能量饮食需求。编制详细的企业预算和生产表。在课程初期,学生们的普遍共识是,营养不良且生活贫困的人个人抱负和动力较低,他们的问题应该可以通过应用美国技术和专业知识来解决。该课程改变了这种态度,增强了学生的批判性思维、解决问题的能力和沟通技巧。课程评估表明,学生们认为在找工作时获取一些国际知识和理解很重要,并且某些动物科学课程应该包含一些国际内容。学生们对全球动物农业有了了解,并认识到粮食生产和饥饿问题的复杂性。
