Alternative Swine Unit
Interest in outdoor pig operations in North Carolina has increased considerably during the last decade. Acceptance by consumers of pork produced under these conditions has helped to establish alternative production systems that are often preferred by small producers. However, management challenges exist for outdoor swine operations, including deterioration of vegetative ground cover, soil disturbance and high nutrient loads that could cause soil and water pollution. Animal welfare in these systems can also be a concern.
The goal of the Alternative Swine Unit is to provide opportunities for researchers to develop and demonstrate methods for production that optimize productivity and animal welfare while minimizing environmental impacts.
Facilities & Animals
Our primarily Yorkshire swine herd is unique in that it has been antibiotic-free for more than 30 years. Since the majority of outdoor swine producers in North Carolina are raising animals without antibiotics, use of an antibiotic-free herd provides the opportunity to use animals for research and demonstration projects that directly relate to producers. Technologies such as estrus synchronization and artificial insemination are used frequently.
Projects & Activities
Through the Center for Environmental Farming Systems, an integrated research and extension approach has been adopted by a multidisciplinary team of researchers, extension agents, farmers and consumers. This team supports the development of sustainable outdoor swine production systems that:
- Are flexible to permit adaptation to a wide range of soils, topography and management practices
- Maintain vegetative ground cover
- Minimize the use of water
- Provide for animal welfare and well-being
- Decrease energy requirements
- Minimize labor needs
- Minimize odor
- Minimize impact on soil, water and air
- Are economically profitable
Projects conducted and planned at the Unit include those involving outdoor or pasture production practices such as site design, selection and preparation, animal control, stocking density, crop rotation, forage use, buffers and filter strips, vegetation management and animal behavior management. Additional research involves pest control (flies, swine internal parasites) and microbiological/disease status of outdoor, antibiotic-free pigs. Research involving breed types for outdoor use has been conducted.
As with all of the CEFS Field Research Units, demonstration and training is an important component of the overall work at the Alternative Swine Unit. Field days, workshops and agricultural professional trainings complement and enhance the research component and interns and apprentices are welcome to be involved.
Outdoor-based swine production systems are perceived as more friendly to animals and the environment. However, in order to assure this, implementation of best management practices like those being studied at CEFS is needed. Farm profitability and viability will also be enhanced through the use of best management practices.
