I think the Murray Grey breed was brought to North America too early, and that they deserve another look. There was a good Murray Grey herd near here, that had some simply awesome cattle. I helped them haul their calves to the local auction mart one time, and I was very impressed with what I saw. The cows were not real tall but most of them weighed between 1600 and 1800 lbs with most being in the lower end of this. There were a few 1800 lbs but they were built like Kenworths on Volkswagon frames. The bull and steer calves weaned at over 800 lbs with no creep and they were fat. The heifer calves averaged 700 lbs. The bull calves were thick, with lots of volume and large well formed testicles. The cows had great udders... nice teat size and tight udders. I think you have to sort through the Murray Grey breed, just like you have to in any other breed to find the right cattle. The ones I saw in this herd were amazing beasts. They were also very quiet cattle to work with. I have also seen some MG that are just too small framed and puddy.
This breeder dispersed a few years later simply because he could not sell his breeding stock. I think these cattle would be very popular today, but in that era, the market was still demanding the race horse kind. When the Murray Grey herd was dispersed, his son started buying cattle. Today, he is one of the largest cattle buyers in this area, and I understand he rolls about $ 7-8 million a month through a local bank in an average month.
