[43]
By using cows that produce offspring within a one to two-week period, synchronized breeding allows dairy farmers to artificially inseminate cows for maximum pregnancy rates with minimal effort. [29] BST is a placental lactogen (PL) hormone and falls under the class of growth hormone, or somatotropin.

A tube may be used to provide some sanitary separation between the blower and the cow, although not every culture that practices cow blowing does so.
For mother cows to continue producing milk, they give birth to one calf per year. If the calf is male, it is generally slaughtered at a young age to produce veal.
