A 9 yr old bull that passes his BSE and moves well would be welcome here. We buy bulls with the expectations that they will be here 5-10 years... YES.... Have an easy calving bull we bought in 2013 so pushing 12 yrs , he is going back in with the heifers in a week. We used him and another we bought the following year specifically for heifers... the other one we just shipped due to a stifle injury.
We have one that is at least 9... bought him as a mature bull in 2015...... he got 29 of 31 preg... all 4-5 months...just preg checked 45 from 2 places, with the 2 opens being "toothless old cows".... and they have nice calves so did their job for us. He just went out with some confirmed preg cows for a summer off, lots of grass there.... then will go back with cows to breed in Nov/Dec... he never got a break last year, went from one group to another... 90% preg.... He is also a sweetheart... calm, quiet, walks right in the trailer, comes to a bucket... sure he is a bull and you always watch them... but I don't have to be "watchful" the way a snorty bull would make me wary.....
Have one bought in 2016, another in 2017, another bought in 2018.... then didn't buy any until 22.... because we had culled some from before we could buy "better" purebred bulls. We try to keep about 10 bulls around for the small pastures we rent and run 10-25 cows at the different ones and they need to be bred.
In between we had culled a couple for attitude, nice, decent, sometimes registered bulls we bought off other farmers that were switching out their bulls....
We do not cull for age... we cull for lack of passing BSE, or for bad legs or injuries, or for attitude...
We buried our old Red Poll bull and he had settled a half dozen cows we put him in with for a second chance.... all bred and calved within 10 days of each other after he was gone... NEVER saw him breed a cow... but he was our #1 cleanup bull even after he was 13... and found him dead one morning.... in the lot with some older bred pet cows... just laid down and went by the looks of it... Okay, not economical... but he deserved to not get run through a stockyards and hauled around on a truck... we do normally sell our bulls before they die....
If all is in working order... I'd buy and use him.
