I toured several leading Angus herds in Britain in June, as well as several Shorthorn herds as well. I also attended the Angus show at the Royal Highland show in Edinburgh which is the biggest show in Scotland. Personally I found that all the cattle in Britain to be larger framed than most here in N America. There were several Irish Angus herds at the Royal Highland show and they were also big framed , with thickness and meat. Several cows in the mature cow classes weighed in excess of 2000 lbs with some close to 2200 lb. The bull that won this show was a long yearling bull that weighed over a ton as well. He was a very good bull.... just way to big framed for over here. I visited one herd that had the biggest and some of the best Angus I have ever seen. Very impressive cattle , but bigger framed.
I do not remember the herd names of the bulls pictured in these AI catalogs, so they may be smaller framed, but I would think that they may be bigger than we think because the Brits really like their cattle bigger than we do.
