Just wondering what blue sires do dairy men use on here? if any, The ones that are easy calvin and pushed by progressive for dairy cows like Manitou DBZ, FTK or more beefy type like DEP RWS and so on. Have had just a handful of well muscled blues purple in colour down thru the years but dont know what sires they were. The rest have only been very average. Have 1 cow still to calf to AZL. I had high hopes until i read here that on another thread that his calves were plain enough too.
What i'm asking is, is there a certain type of blue bull that crosses well with friesians (colour wise & muscle) or is it just pure hit and miss?
