Update

We continue to work with local and state health officials, as well as NC State and N.C. A&T State Universities, to monitor the evolving coronavirus (COVID-19) pandemic.

The second version of this Course of Data Analytics for Poultry and Swine Industries is available in a virtual interactive format and self-paced on July 19, 2021.

Please know that these changes are intended to enhance learning opportunities and at the same time protect the health and safety of our community while striving to provide the resources and services you need. We will continue to closely monitor the situation and act consistently with local, state, and national recommendations.

Additional resources can be found at the links below:

We thank you for your patience and understanding at this time, and we are committed to continuing to serve and growing our community. Together, we will see it through, one day at a time.
