The world’s best rumen pH bolus

Smaller, more accurate, longer lived than any other.

At eCow we have been making boluses since 2007. In that time we have managed to improve the technology so that our boluses are the best choice for researchers in countries all over the world. Our boluses are designed for not only research and testing but also practical use on farms. We are based in United Kingdom where we manufacture, test and ship all of our products.
