Well, our prize HuCow Katie has big udders, that’s for sure! But her teats are not that big. So we need to work on increasing their size to make them more sensitive, longer and bigger nipples will be much more efficiently milked by machines like the red cow milker. We made new transparent nipple training cups especially for Katie, and hooked them to the very powerful electronic breast training machine. This machine is designed to enlarge the entire breast with big cups, so using a smaller cup will make it even more powerful.
