A switch to Angus 70 years ago has paid dividends for one Woolsthorpe stud.
The land, where Claremont Angus stud is based, was first purchased in 1932 by co-principal Liz Glasgow's grandfather Stanley White.
He originally ran Romney sheep and Herefords, with crops grown for the war effort, during World War II.
"During this, there were apparently many 'discussions' around the dining table about having a few Angus," Mrs Glasgow said.
"After much harping from my young father, my grandfather gave in and bought 40 Angus heifers from the Kahlua stud in 1940."
She said the breed proved to be a hit, in the sometimes trying conditions of the south-west.
"In our cold windswept winters near the coast, the Angus would always go out and graze and had higher conception rates than their Hereford mates," she said.
The last Herefords were sold in the early 1960s, and after strikes, and difficulties with shearers, the sheep went too.
"Graeme and I now run 300 APR Angus breeders plus 60 replacement heifers and sell 50 APR Angus bulls each year," she said.
The family had plans to increase livestock numbers, with the development of more pasture.
The foundation Kahlua bloodlines were followed up with purchases at the Royal Sydney Show, including Victoree Abaridy in 1970, and from Glen Arm in 1982, 1983 and 1985.
"We used to buy in bulls and breed our own from a few specially selected cows but found the progeny was not much better," she said.
"So we stopped doing that in the early 1990s and concentrated on artificial insemination.
"We found the results were a lot better and each crop of calves is better than the last.
"We now AI about 120 of our 300 cows to around five or six AI bulls and then all our cows are joined with follow up Claremont cub bulls."
Original breeding aims had been retained, since her father's time.
"I think they are the same as my father taught me - shape, structure and style and buy a bull to suit your cows," she said.
Temperament was one of the most important traits.
"This policy works for us, our calves are as even as peas in a pod, and that makes them very easy to sell into a lot of markets," she said.
Cows were joined between June to mid-August, at a ratio of one semen-tested, 18 month-old bull to 25-30 females.
Heifers were first joined at 14 to 15 months, to calve at two years-old, with two bulls to 25 females.
More recently Claremont had been using bloodlines from WMR Timeless 458 (US), Jindra Double Vision (US), HF Tiger 5T (Canada), and MAR Innovation (US)
"We have also used semen from Texas Western Express, Texas Global and Texas No Regrets, plus Musgrave Stunner and Baldridge Beast Mode," she said.
