ABSTRACT: An experiment involving a total of 1,320 crossbred pigs was conducted at 3 universities to assess the effects of various levels of lactose in diets during phase 3 (wk 3 and 4 postweaning) of a 4-phase starter program.
Pigs were weaned at 15 to 20 d (6.2-kg initial BW) and allotted to 5 treatments.
