At college I was taught that a cross bred when crossed with another cross bred does not breed true. If you put a Mule ram on a Mule ewe you don't get pure Mule lambs. How can that be true of Kiwi Cross ? If Kiwi Cross is a breed in it's own right, then crossing it back on itself surely negates any benefit from heterosis/hybrid vigour ?

I have used kiwicross on Scandinavian red crosses, and there is some variation in how much the jersey shines through. It will be over another year before the biggest batch are mature enough to see the final difference, some of these will probably be 2nd generation kiwicross. At the moment they appear to be fairly uniform. Not much help, I know, try some and some.

We've been using kiwi cross since 2007 (scotts Northsea), our service straws are split 1/3 nz Friesains, 1/3 kiwi cross and 1/3 Danish Jersey and aim for a 12F 4J, bbut changing breeding policy last year and used sexed Jersey and now probably going to be 8F 8J, pictures are of this year's calving heifers in the summer (their the ones with green tags), their a very even bunch overall.

With award presentations by Tom Bradshaw, Vice President of NFU, 24 farms took home the evening’s top awards for highest yield and highest potential yield achieved for wheat, winter and spring barley, oats, and oilseed.
