Artificial selection to obtain cows yielding higher milk output represents:

1.  Directional, as it pushes the mean of the character in one direction
2.  Disruptive, as it splits the population into two, one yielding higher output and the other lower output
3.  Stabilizing followed by disruptive, as it stabilizes the population to produce higher-yielding cows
4.  Stabilizing selection, as it stabilizes this character in the population
