Jacob’s reply begins by repeating the thoughts that have been expressed in verses 26-28.

You yourself know … you: see verse 26.

How your cattle have fared with me: cattle refers to all of Laban’s animals or flocks and not just to his cows and bulls. This statement refers to the increase in Laban’s animals and may often be translated, for example, “how much your animals have increased.” See Good News Translation. With me means in this context “since I have been here,” “under my care,” or “with me taking care of them.”
