The COWculator

Our COWculator forecasts how much extra margin you could make using Knewe® prebiotics (based on milk production). Just put in your name, email address and some key information about your dairy herd, and we’ll do the rest.

"Recent analysis of food production systems in New Zealand has shown that dairy products are very effective in fulfilling [dietary] needs. We have to find ways to carry out dairying in the most sustainable and ethical manner, but at the same time try to improve the conversion efficiency of plant production into dairy products – any means of improving conversion efficiencies such as the use of rumen prebiotics will help us achieve a healthy and balanced human diet for a healthy planet."
