A total of 1,100 nursery pigs (6.8 kg BW) were used in a 42-d study to determine the effect of increasing soybean hulls (10 or 20%) and soybean hull particle size (unground = 671 μ or ground = 398 μ) in nursery pig diets fed in both meal and pelleted form. Pigs were randomly allotted to a 2x2x2 arrangement of treatments with 11 replications per treatment. Several interactions were observed, however it would appear that grinding soybean hulls improved G:F and reduced ADFI in meal diets, but did not change G:F and had less effect on ADFI when pelleted. Grinding soybean hulls slightly improved caloric efficiency in meal diets, but not in pelleted diets. Increasing soybean hulls from 10 to 20% increased ADFI and reduced G:F in meal diets, but were not changed in pelleted diets leading to a greater improvement in caloric efficiency in pelleted diets than meal. Grinding soybean hulls below 617 μ decreased ADG (P<0.01) and ADFI (P<0.08) and tended to reduce final weight (P<0.08). Pelleting provided the expected improvement in ADG and eliminated the negative effect of increasing soybean hulls on G:F.
