Most Dairies today use sexed semen for replacement on Top Top performer cows, the trend now is to use AI on mid-bottom performers and sell day old feeders, what some companies like wulf are doing is using specialized bulls(Top dollar metrics and hide color) like a Limflex(at least 75% Limousin and homozygous for black hide), they purchase the feeders from the dairies as soon as possible and send them to calf ranches. strait Jersey bull calves are basically worthless, the F1s of this cross earn top dollars.
I would like to point out that I am using the previous example as reference of what a cross of a scrawny looking breed may look or perform if crossed with a powerful terminal line, not that Wagyus are a dairy breed, in the case for the OP since the scrawny looking breed in this case is a Wagyu bull and not cows(Wagyu cows are very expensive, rare in the market hens' teeth and 95% of the time are used to produce more Wagyus), the guys in the know how have been using good milking simmental/fleckvieh cows.

You will not find many if any on that type of cross for a few reasons which are not entirely economic in nature, First in the Japanese market they cross Wagyu with Holstein about 99% of the time, the Japanese will favor that cross over any other cross including the mythical Angus, In Australia they prefer the Wagyu/Angus cross instead because the marbling is very close to it(lower than Wagyu/Holstein cross) but produces way more beef all of them stay at the F1s as that what Japanese requests, now for the rest of the world including the U.S.A people get top dollar for Prime and Choice so the other half of the equation/cross does not need to be a marbling breed and a good milking continental herd of cows will do just fine(perhaps not as productive or efficient as Terminal sire x small efficient small marbling cows)
In Japan when managed like regular Wagyu, these F1s(Wagyu/Holstein) Will grade up to A4 and pure Holstein will grade up to B2, when F1s are managed in Australia you don't see that kind of marbling,
here a few shots of the A5, A4 and B2 carcass from Japanhttp://www.tokyourbankitchen.com/japane ... gyu-japan/
