Globalization has imposed many changes in economic and political arenas in many regions around the world, but scientific knowledge has no boundaries and multinational collaboration can increase scientific knowledge by fostering the discovery of techniques and resources that can assist current and foreseeable problems, including hunger and sustainability. Ruminant animals, for instance, convert human-inedible resources into animal products for human consumption, and humankind have benefited from this prehistoric symbiotic relationship because ruminants can adapt to diverse environment (clime, soil, and vegetation), making them apt to inhabit virtually anywhere in the world. Collectively, humans of all socio-economic and socio-cultural strata have relied on animals for energy and/or protein consumption, wool, and draft power. This relationship has sometimes led to extreme production systems (due to economy-of-scale factors in some countries) that may cause irreversible damage to the environment. Thus, appropriate management of animal production is essential to enable long-term, sustainable continuation of this human-livestock relationship within acceptable animal welfare criteria. Proper education is the first step. Study abroad courses expose students and faculty to new endeavors in animal science and provide effective communication skills for the advancement of science. Internationalization programs minimize technical and economic disparities among countries. The educational exchange among countries is imperative to prepare leaders and extend the frontiers of knowledge in sustainable livestock intensification. For university and agency researchers, international exchanges advance technical, socio-economic, and environmental differences and strategic possibilities among countries. International business partnerships are critical for major multinational companies based in the United States involved in animal products and genetics, seed, fertilizer, and agrochemicals. Therefore, the investment on international research collaboration increases our awareness of human resource needs and enhances the career opportunities of our students by preparing them not only with technical expertise but also with language capabilities and in-depth understanding of other cultures.
