Primo is a trump x desert rose 004 full sib to sullivan's solution, cate's bloodstone, and hahn's big & rich bulls. he is syndicated and i don't believe semen is on the open market. however the owners are often willing to throw in a couple straws when u buy females from them. i saw him two summers ago at trans ova and he is quite impressive, i still preffer solution to primo and big & rich (haven't seen bloodstone) primo has also been accused of not breeding as consistantly as solution and bloodstone, however that is mostly due to the fact that primo was used on a wider variety of cows and cow types than solution and bloodstone who are bred almost exclusively to the "best" cows in the breed, so i suppose you could make the argument that he is more proven on the fact that there should theoretically be more calves out of him out of different types of cows. with all that being said when it all boils down the best solutions bloodstones and primos are all great cattle and you would be satisfied to have any of them
