"Have not used any Ricardo nor bought any offspring, but have not been terrifically impressed by what I have seen--might just not be my type of cattle though"
so I felt bad about making this statement because I probably wasn't fair: my primary criticism is for phenotypic reasons: if I'm breeding for a show animal, which in many cases is the case, he's not the bull I'm going to use (and if you look through the show results for the National Junior Heifer Show, which many people use as an indicator, you're not going to see his name there). If you're looking for something that's going to bring you pounds at slaughter, I don't know how he would stack up, BUT I haven't seen his name at the top of the sire list on the bull tests or steer feedouts either where normally you see Briggs. He does have a large number of offspring in many prominent herds, so he must have some merit (you can do a sire search on the Santa Gertrudis website). Ricardo has 439 active registered offspring. He does have a number of Genestar markers which he should pass on to offspring.
EDIT: My Boolean operator was off when I went looking for offspring with offspring and turned up 8 results. I tried it on another animal and did not receive results when there should have been. Foot in mouth syndrome.
