I've never used the bull so I can only go by what I can see in registrations and ratios. There was still a good group of calves registered on of 5N this spring, but overall he hasn't seen as much use as a more famous half brother M326. I've seen a handful of M326 progeny and overall I like them. Also I think they'd be much easier to market, with the added exposure of their sire. However good animals should sell well any way. M326 and 5N have similar ratios on IMF, but then 5N falls to around 99% on REA while M326 stays above 100 at 101%. Based on the ratios it looks like 3008 sired a lot of IMF, but not some much REA. M326's dam ratioed on 10 calves 103.9% for REA and 105.2% for IMF. On 5 calves, 5N's dam was under 100% for REA and only 101.5% on REA. That's about all I can say. Some of it probably doesn't mean too much though. What were you looking to add with 5N. IMO there's much better reg. hereford AI bulls out there.
I also attached a younger photo of him that I got off the AHA site. It doesn't impress me too much.
