Animal and Rangeland Sciences
The multiple facets of Animal Sciences provides current information on the different production methods involved in the care and management of companion animals, livestock, and poultry. These facets address the production of meat, milk, eggs, wool, and other animal services such as companionship, work, and recreation. In addition, the department addresses the care/well-being of animals as it impacts and enhances the human/animal bond along with the production levels of those animals. Essential to this information is the knowledge generated from the field of animal behavior/bioethics, genetics, nutrition, reproduction, and physiology.
The curriculum designates university and departmental requirements for the BS degree in Animal Sciences. In addition, there are five specialized program options students can choose to pursue. These include: Animal Behavior, Animal BioHealth/Pre-Professional, Animal Production, Equine, and Rangeland Sciences. Diverse teaching and research programs allow students to gain skills, knowledge, and practical experience. This will prepare students graduating from the program to pursue an assortment of employment opportunities. Potential employment areas may include farm and ranch management; product quality assessment of meat, poultry, eggs and milk; the Cooperative Extension Service; sales or technical service with commercial feed, seed, and chemical companies and pharmaceutical firms; agricultural loan officer; government agency positions at local, state, and federal levels; animal welfare auditing; animal behavior consulting; business management; as well as journalism, mass media, and public policy. In addition, students are prepared to go on to advanced studies in animal sciences, veterinary medicine, pharmacy schools, human medicine, nursing schools, dental schools, and education.
Graduate work leading to MS or PhD degrees in Animal Sciences may involve research projects that concentrate on areas such as animal nutrition, dairy production, embryo physiology, endocrinology, growth and development, livestock management, nutritional biochemistry, and reproduction physiology.
Cooperative Programs
Students transferring after one or two years at a community college should also be able to complete the requirements for a BS after three or two years, respectively.
Rangeland Sciences
Rangeland Sciences consist of the study and sustainable management of rangelands across a variety of biomes, from arid deserts to mesic grasslands, to tropical savannahs. The program takes an interdisciplinary approach to provide advanced scientific knowledge regarding multiple ecological processes and social drivers influencing rangeland ecosystems around the globe. Students in Rangeland Sciences gain the skills and knowledge needed to fully understand and effectively manage rangelands for improved productivity and enhanced ecosystem resilience. Students graduating from the program will be able to integrate contemporary rangeland ecology and management principles into systems-based decision-making frameworks to promote ecological resilience, sustainable societies, and thriving economies in rangeland ecosystems. The Rangeland Sciences degree program is available both on-campus and via Ecampus.
The curriculum includes university and departmental requirements for the BS degree in Rangeland Sciences. It also provides the opportunity for doing a minor in the subject of interest for the student (e.g., Animal Sciences).
There are a variety of scholarships and student employment opportunities available to students in the Rangeland Sciences program. There are opportunities all year along for students to gain practical experience in various research projects conducted by faculty in the program. Also, there are several options for summer employment with private industry, government agencies, and on range research projects.
The Rangeland Sciences program is accredited by the professional Society for Range Management (SRM). Accreditation ensures that graduates from the program have the necessary knowledge to join the rangeland science profession regardless of where in the world they may end up launching a job. Accreditation with SRM also helps to build a map to Federal OPM course requirements for multiple 400-series Biological Sciences positions (i.e., 401 Natural Resources Management and Biological Sciences; 408 Ecology Series; 454 Range Management Series; and 457 Soil Conservation Series). This is an important feature of the Rangeland Sciences program as many students go on to careers with federal or state agencies.
Graduate work leading to MAIS, MS, or PhD degrees in Rangeland Sciences may involve research on habitat management and restoration, watershed and riparian systems management, land use-environment relationships, ecohydrology, agroecology, ecophysiology, pastoral systems, and landscape ecology.
