yajambee Angus

Our Angus cattle stud is centred on two basic principles – fertility and longevity.

We strive to achieve longevity in our cattle with maternal function right at the top of all breeding selection criteria we make.

This focus on maternal function and longevity along with careful production practices ensures that our herd and any bulls or females we sell contribute to creating a sustainable farming future in Australia.

Gabe oversees the stud program himself and brings a passion for sustainable beef production. He can be contacted directly for stud enquiries.

The basis of our breeding decisions


The focus at Yajambee is our cow herd.

In our opinion fertility should be the number one driver for success in any cattle breeding operation. A cow producing a calf each and every year is not only an obvious profit benefit for any grazing enterprise but she is also an important part of the current and well-documented Carbon Cycle complexities we hear about nearly every day…

Over 80% of the world’s population make a conscious decision to eat meat products. Our business along with the decisions any grazier makes as custodians of the land we farm become a key part of that choice. By selecting cows that are highly fertile and “culling” those that are not we will, over time, retain a herd of cows with superior fertility that go out each year whether in drought conditions or good times and each produce a calf. In doing so we are not “wasting” recourses on animals that are not benefiting our production systems and thus contributing to the changing of natural Carbon Cycles without providing a resource for our consumption in return. Beef cattle and pasture management play an important role in carbon sequestration and when managed correctly can produce a net positive carbon footprint. Those “wasted” resources on the less fertile cattle are not limited to just the pastures they graze but every expense, product, veterinary treatment, transport, fuel/energy cost, health supplement and the like that form part of maintaining any cattle herd.

Certain aspect of fertility in Angus cattle are heritable and as such have a strong likelihood of making a positive difference in any herd when genetics are introduced. Our fertile females produce fertile calves, the bulls we retain for sale will make a positive fertility difference when introduced into any herd.

Our females are first joined at 15 months of age, they MUST have their fist calf at two years old unassisted and calve each and every year following to maintain her position in the herd. Fertility is the most important selection trait at Yajambee Farms

the functional working life of an animal


Angus Stud cattle have an extensive history of performance recording using EBV’s (Estimated Breeding Values). There is one “trait” however that is not measured using EBV’s - Longevity.

Longevity, in fact, relates directly to many of the other traits spoken about by producers and recorded directly using EBV’s. Traits like structural soundness, scrotal size and calving ease as well as survivability and doing ease all have a direct impact on the longevity of an animal. Without these traits it is unlikely that an animal will have longevity. So, directly or otherwise in focusing on longevity in selecting the females we retain in our breeding herd and the bulls that we use over them all of these other important traits are closely considered too. If we can extend the longevity of the animals in our herd we will obviously pass on a lot of those desirable traits to their progeny which benefits our own clients and the industry as a whole.

Longevity in cattle is directly related to the beef industry cost of production, which apart from our love of cattle is basically why we are in business - so that we can afford to pay for what we need to live! A bull that can go out and work hard (service 50 or so cows) for 4 years is going to be twice as cost effective as a bull that “breaks down” after two seasons from a lack of structural soundness for example. If he cost $10,000 and sires 200 calves over 4 years he has cost you $50.00 per calf (excluding many other factors obviously, like recovery costs when he is sold etc). If he breaks down in two years, then the cost per calf effectively could be double that or $100.00 per calf. Further to this and when selecting bulls to introduce into any herd great care should be taken - bulls have a significant “multiplier effect”, they will pass their traits onto their progeny which will stay in a breeding herd for many years to come.

Focusing on longevity in bull selection will increase profitability by reducing cost over time. The $10,000 bull that works for 4 years will cost you less long term than two $7,000 bulls over the same period that are not bred to the same quality, he will also influence your breeding herd in a more positive manner with the genetics he leaves behind.  

Longevity and all the important EBV traits it covers could well be the most important (and often overlooked) quality when breeding selections are being made in any herd. Often when buying bulls people look firstly at the EBV data for an animal and then at the physical characteristics, we believe it should be the other way around. A bull should first be observed for his balance, his conformation, the way he walks, his softness of coat and the way he carries his head. If he passes these initial observations (all of which are not “measured” with EBV’s), then we can use EBV’s to assist our selections further. Breeding good quality cattle is not achieved successfully long-term using data alone.

Longevity is second only to fertility when we make our breeding and selection decisions at Yajambee Farms.
