DSD 5.2 | Stop fresh cow subclinical mastitis in its tracks without withhold

Getting the fresh cow off to a strong start has ripple effects for her entire lactation. Subclinical mastitis rarely gets treated due to an unawareness or a lack of interest in pulling her from the tank. Nisin is a naturally occurring antimicrobial that’s been used widely as a food preservative. Dr. Zelmar Rodriguez and his team from Michigan State University looked at using this familiar antimicrobial to treat subclinical mastitis. The result, reduced clinical cases of mastitis.

Listen in to learn more about the return on investment of using Nisin on subclinical mastitis found in the first week of milk using CMT.

These findings are published in the recently released paper titled: Economic impact of treatment of subclinical mastitis in early lactation using intramammary nisin
