Advanced Animal Diagnostics continues to raise new capital. After closing on $3.5 million earlier this year and $15 million in 2015, the livestock technology company is now looking to raise $3 million.

The news came in a securities filing earlier this week.

AAD already has closed on $1.5 million in debt.

In June, AAD raised just over $3.5 million in equity from a mix of 10 investors.

Back in March, the company disclosed the start of the new round, saying it had closed on just over $1.7 million of a targeted $3.43 million.

Last December, AAD raised $15 million.

The company develops products that diagnose livestock diseases. It says its technology creates more precise care of animals so they live healthier, more productive lives.

The company’s website notes: “With powerful diagnostic technology, we can detect diseases earlier so producers can take action earlier – and prevent losses. In the dairy industry, our QScout MLD test detects subclinical mastitis infections before losses occur.”

AAD, previously a member of BD Technologies Bioventure Center incubator in the Research Triangle Park, was founded in 2001.
