IT WAS a day for swapping recipes for honing fertility at Gyranda last Thursday.

The nation's leading beef geneticist Dr David Johnstone and arguably the most entertaining cow judge Grame Hopf swapped ideas for what makes the perfect cow at the Gyranda open day.

A crowd of more than 70 descended on the picturesque sales complex near Theodore from as far away as Bundaberg, Brisbane and Goondiwindi. They came to learn why structure is so important in breeding females, and why udder development, hip slope and not getting too fat is critical to ensuring your cows can calve out easily and raise a healthy calf every year.

Dr Johnstone painted a stark picture of the importance of maintaining data to determine fertility of females.

Fertility is the one trait that cannot, he insists, be picked by eye.

The most recent trial work reiterates that in santa gertrudis the days-to-calving estimated breeding values is closely correlated to all fertility traits.

It is a valuable tool that has the potential of lifting preg testing rates by 3%-5%.

It's available on those bulls you buy now, giving you a clear picture of the future fertility of their daughters.

Of course no Gyranda open day would be complete without a full field of the 2016bull sale team, a hearty lunch and vigorous open discussion covering birth weights and calving ease, poll gene testing and semen morphology.

The Gyranda sale is on Thursday, September 15, comprising 100 bulls, including 60 polls and 77 above-breed average for fertility days to calving EBV.
