Calves eat both grass and milk while with their mothers. It takes more grass to produce enough milk for a calf to gain a pound than it takes for a calf to gain a pound on grass alone.
Now, that being said, early in a calf's life he needs nutrients from both the cow's milk and from grass, but later on the calf can do just fine with minimal or no milk.
Consequently, why have heavy milking cows that consume more grass than necessary to produce more milk than is needed by the calf. Also, cows that milk heavy typically have a harder time staying in condition and often don't breed back as easily as cows with less milk production (because they put so much energy into making milk).
Heavy milking cows also tend to have more udder problems, so heavy milking cows typically don't stay in the herd for as many years of production as moderate or low milking cows.
I prefer Gelbvieh over Simmentals and Braunviehs. According to data from the Meat Animal Research Center (MARC) in Nebraska Gelbviehs wean more pounds of calf per cow exposed to the bull than Simmentals. This is huge when determining profitability of the cow herd.
I prefer Gelbviehs over Braunvieh because there EPDs are likely more accurate due to a much larger number of Gelbviehs in the Gelbvieh database than Braunviehs in the Braunvieh herdbook.
