Mark, we keep a eye on daily gain in the heifers we raise. Last year we kept 26 heifers they are from Dubuc casanova 505C, Wr Wrangler 601, SOS Chuckwagon 54C, Dubuc Craig 5586C, SVY Grizzly 521C, MVY Xplorer 21X and Lt Bridger 9191, most of them have calves from Dubuc Diego 605D. Diego is calving like a charm but we didn't raise an heifer from him yet they lack daily gain but some of his bull calves find a herd for calving the heifers or the commercial breeders who fear charolais bulls, often they had bad luck with french influences bulls that are still raised here in Quebec.
We have some cows that weight near 2000 pounds, near half of my cows have Shelco made easy 512R in the blood they are fat in our system here, we winter them with free choice corn silage and the winter is long here so we need to focus in calving ease. My birthweight average is still around 93 pounds. We check for a Commisioner son, maybe an homozygous one will be in our AI tank next year, always in need of a new calving ease bull!
