Producing high-quality, low SCC milk has always been a priority of Ontario dairy producers. Please make sure to visit this site on a regular basis for information on how to best control SCC levels within your herd while minimizing the unnecessary use of antibiotics. "Using a little as possible, but as much as necessary" to ensure excellent milk from Ontario's dairy herds. When excellent milk quality and low herd SCCs are consistently achieved, therapy programs should be revisited. Selective use of antibiotics at dry-off time will reduce overall antibiotic use. Only cows with infections likely to respond will be treated.
