An experiment was conducted to determine the effects of replacing dent corn with naked oats (Paul) on growth performance of early-weaned pigs.  Crossbred pigs (n=200) were weaned at 14+1 d and allotted to five dietary treatments in a three-phase starter program.  During Phase I (d 0 to 10), the basal diet was corn-soybean meal with 20% dried whey, 7.5% spray-dried porcine plasma, and 5% fish meal fortified with vitamins, minerals, and antimicrobials.  In Diets 2 - 5, naked oats replaced 25, 50, 75, or 100% of the corn, respectively.  All Phase I diets were pelletted and contained 24% CP, 1.65% Lys, and .90% SAA. Phase II (d 11 to 21) diets were fed in meal form and contained 22% CP, 1.4% Lys, and .78% SAA.  In Phase I and II diets, naked oats replaced corn on an ME basis.  A common Phase III diet (corn-soybean meal, 20% CP, 1.25% Lys, .71% SAA) was fed in meal form from d 21 to 42.   ADG, ADFI, and F/G for pigs fed the five diets were, respectively: (Phase I, d 0 to 10) 100, 127, 109, 132, 136 g/d; 132, 159, 136, 159, 159 g/d; 1.32, 1.30, 1.25, 1.21, 1.15; (Phase II, d 11 to 21) 232, 255, 214, 259, 232 g/d; 327, 377, 341, 368, 359 g/d; 1.41, 1.48, 1.60, 1.43, 1.55; (Cumulative, d 0 to 42) 273, 300, 259, 305, 300 g/d; 473, 495, 436, 500, 495 g/d; 1.73, 1.66, 1.68, 1.63, 1.66.  Growth rate and feed intake increased linearly (P<.10) when naked oats replaced corn in the diets during Phase I and II.  For the entire experimental period (d 0 to 42), inclusion of naked oats in the Phase I and II diets did not affect daily gain, feed intake, or feed/gain (P>.10).   These results suggest that naked oats can replace a portion of all of the corn in the Phase I and II diets of early-weaned pigs.
