Daf Shevui to Kiddushin
I should note that the relationship between meshikhah and mesirah is disputed. Rashi holds that mesirah is a more effective method of acquisition, and therefore one who holds that the animal is acquired through mesirah would hold that it is not acquired through meshikhah, the less effective manner. But the Tosafot hold the opposite—meshikhah is more effective.
