The objective of this study was to evaluate Solpro500 (a wheat hydrolysate containing a high level of glutamine) as a replacement for spray dried porcine plasma (SDPP) in diets fed to nursery pigs. One hundred and eight pigs (Dalland, $5.39{\pm}0.80$ kg BW) weaned at 21 days were assigned to one of three treatment groups for a 28 day feeding trial. The experimental diets were based on corn and soybean meal and were supplemented with either 8% SDPP, 4% SDPP plus 4% Solpro500 or 8% Solpro500. Each treatment was fed to six pens with six pigs per pen (4 barrows and 2 gilts). The experimental results indicated no significant difference (p>0.05) in daily gain, feed intake or feed efficiency for pigs fed the three experimental diets. However, the diarrhea index for pigs fed either 4% SDPP and 4% Solpro500 or 8% Solpro500 was lower (p<0.05) than that for pigs fed 8% SDPP. No differences (p>0.05) were found in the apparent fecal digestibility of dry matter, organic matter or crude protein between pigs fed the three diets. The intestinal morphology (villous height, villous width and crypt depth) was not affected by diet treatments (p>0.05). In conclusion, Solpro500 SDPP can replace SDPP without any negative effects on nursery pig performance.
