The Lowline Calf is the offspring of a Bull and Lowline Cow. When you harvest milk from your Dairy Farm (with 1 Bull and at least 1 Lowline Cow inside) there is a chance that a Lowline Calf will be born. When you harvest from your Cow Pasture with at least 1 Lowline Cow there is a chance that a Lowline Calf will be born. The Lowline Calf can be placed in the Baby Playpen. When harvesting a Baby Playpen containing at least one Lowline Calf, it is possible to find two calves. One Lowline Calf is placed in the player's gift box and the other is shared to the player's wall.
