    The temporal pattern of changes in milk fatty acids for the different treatment groups. The 3 treatments were control (water infusion), abomasal infusion of stearidonic-enhanced soybean oil (SDA-abo), and rumen infusion of stearidonic-enhanced soybean oil (SDA-rum). The 7-d infusion is shown by the boxed area, and the oil infusions (every 6h) provided 57g/d of stearidonic acid.
