About Our Cattle

We focus on producing quiet, high quality seed stock for stud and commercial buyers, placing great emphasis on growth and muscling.

Cadfor Murray Grey stud was established in 2001 when we purchased the property at Binda. Prior to this, the stud operated at Picton as Wilton Park Murray Greys, in partnership with Rod’s parents, since the 1970’s. Click here to see how Rod got involved with Murray Greys.

For 30 years the Wilton Park Murray Greys were heavily culled for temperament, fertility and milking ability. After taking over the herd, we assessed that the cow herd needed to improve in muscularity and could benefit from a modest increase in frame score. Bulls were selected to initiate these changes.

Cadfor cattle are paddock reared and are supplemented as seasonal conditions dictate. We do not routinely feed grain, only providing hay or silage and possibly a protein supplement depending on pasture quality and availability. We try to provide the best possible pastures to allow the cattle to express their genetic potential under commercial conditions. We record weights at birth and weaning and routinely scan males and females for carcase characteristics. All data is submitted to BREEDPLAN for analysis.

We rear the majority of our heifers on the expectation that they will be better, on average, than their mothers. This gives an advantage for Breedplan analysis because the size of the contemporary group is large and the estimate of genetic worth is more accurate. We assess the heifers on their ability to produce a calf and cull them based on the 200 day growth rate of their calves. Rearing many heifers to replace their mothers gives another genetic advantage, that of decreasing the generation interval thereby speeding our genetic progress.

A major aim of our cattle management was to be able to sell our spring drop steers at an average of about 300kg by April. In our cold climate steers held over winter make very little growth from April to August. We reached this goal in February 2013 when we weaned our spring drop calves at an average weight of 297 kg. The 200 day weights of our weaners is now 318 kg.

To achieve this growth rate we have imposed a heavy selection pressure on the growth rate of calves. When we moved to Binda our calves grew at an average of 1 kg per day, which is slightly better than the district average. Our calves are now growing to weaning at an average of 1.40 kg per day on our pastures which comprise mainly well fertilised native species with sub clover and some improved grasses. Cows whose calves are growing at less than 1.2 kg per day are culled unless there is some obvious problem that affected growth.

Most of our mature cows weigh between 600 – 700 kg and have frame scores between 5 and 6. We like deep bodied cows that maintain their weight through lactation and are able to cope with our freezing winters. Of the females currently in our herd 70% are in the top 20% of the breed for at least one of the financial indices.

Biggest is not always best. We look for:

moderate birth weight – oversize calves give calving problems. However bulls that produce very small calves produce daughters that have calving problems. A 38 kg calf is about ideal for our operation.

moderate milk production – the cow must produce enough for the calf to grow. Cows that produce too much milk lose weight and do not go back in calf. A calf that get too much milk is prone to scours. A calf on a good milker will often not do much grazing and weaning comes as a big shock. We like to see the calves grazing.

moderate mature cow size / frame score – big cows suffer in our cold conditions. Unless they can get through the winter without losing condition they produce poorly next lactation.

moderate fat cover – some fat on their backs helps our cows get through winter and provides enough fat in their offspring to achieve good carcase and eating quality. Cows with too much fat (the ones with fatty deposits around the hips and pins) appear to have the equivalent of insulin resistance and get sub-clinical laminitis and feet problems.

We use Cattlelink to record and analyse our management data. Details here.

Our stringent culling program has seen the Breedplan figures of our cattle increase rapidly as seen in the graphs below.

We only show our cattle in commercial and steer classes at our local Crookwell Show Commercial Section and take these animals straight from the paddock. We won the Supreme Champion Commercial Exhibit four times in five years, all with different animals and under different judges. Our results are shown here. In 2015 the entry requirements were changed to exclude purebred animals so in future we will be exhibiting Grading animals.

We breed some black Murray Grey cattle to meet the market demand for this colour and to provide a desirable alternative to other black breeds. Coat colour explanation here.

We are committed to provide the highest level of care for our cattle and follow The Australian Animal Welfare Standards and Guidelines.    We are in the Johnes Disease Market Assurance Program at MN3 level.

MISSION STATEMENT
