ABSTRACT: A total of 60 castrated male pigs (Yorkshire x Duroc, initially 17.36 kg) were used in a 42-day trial to evaluate the effect of complete feed feeding level and morning glory on growth performance of growing pigs. Pigs were allotted to pens and randomly assigned to three dietary treatments: A) completed feed fed ad libitum; B) complete feed fed at 75% of intake of treatment A, and C) treatment B with ad libitum availability of morning glory. The design was a completely randomized design (CRD) with five pens (replications) of each treatment with four pigs per pen. Average daily feed intake (dry matter basis) was higher (P ad libitum was greater (P ad libitum or pigs restricted fed but provided morning glory (1.63, 1.56 and 1.65, respectively). For economics, feeding complete feed ad libitum improved (P ad libitum resulted in the greatest growth rate and profitability. Offering morning glory (Ipomoea. aquatica) to pigs fed a restricted level of complete feed did improve final body weight, but the extra cost of feeding morning glory offset this advantage resulting in similar profitability on an income over feed cost basis.
