Cahill said the family entered five cows in all last week.
''We usually enter about 10 or 12 cows. There's not as many animals here as last year, but it's still good for the show to have the cattle here and for us it's an opportunity to advertise what we've got.''
He said complying with the new biosecurity protocols, developed to manage the risk of Mycoplasma bovis, had been relatively straightforward.
''It's put a few people off, but hopefully we can show that it can be done with the right measures in place.
''There have been a few changes, but it's quite manageable with the breeders all working in together.''
While many larger dairy farms began retiring cows at 4-years-old, Cahill said 10-year-old Carra produced a whopping 800kg of milk solids last season.
The herd averaged around 700kg of milk solids per cow per season.
Calving was staggered from March to October, with milking all year round.
Young stock were kept on farm, with the only off-farm feed being wheat and some minerals to feed stock in the shed.
