AB  - The objective of this experiment was to determine the effect of increased 
      concentrations of full fat rice bran (FFRB) or defatted rice bran (DFRB) in diets 
      without or with supplementation of an exogenous xylanase on growth performance 
      and blood characteristics in weanling pigs. A total of 532 pigs (9.3 +/- 0.5 kg 
      initial BW) were allotted to 14 diets in 4 blocks and 8 replicate pens per diet 
      in a randomized complete block design. There were 4 or 5 pigs per pen. A basal 
      diet containing corn, soybean meal, and whey powder and 6 diets containing corn, 
      soybean meal, whey powder, and 10, 20, or 30% FFRB or 10, 20, or 30% DFRB were 
      used. Seven additional diets that were similar to the initial 7 diets with the 
      exception that they also contained 16,000 units/kg of microbial xylanase were 
      also formulated. On the last day of the 23-d experiment, 2 blood samples were 
      collected from 1 pig in each pen. Tumor necrosis factor-alpha (TNF-alpha), IgA, and 
      peptide YY (PYY) were measured in plasma samples and blood urea nitrogen (BUN), 
      total protein, and albumin were measured in serum samples. Initial and final BW 
      were not affected by the inclusion level of FFRB or DFRB or by the addition of 
      xylanase. The ADFI linearly decreased ( < 0.05) as inclusion of FFRB increased in 
      diets and there was a tendency ( = 0.08) for reduced ADFI as DFRB was increased 
      in the diets. Pigs fed diets containing DFRB had greater ADFI ( < 0.05) than pigs 
      fed diets containing FFRB. The ADG increased and then decreased (quadratic, < 
      0.05) with increasing level of FFRB or DFRB in the diets. The G:F linearly and 
      quadratically increased ( < 0.05) as the inclusion of FFRB increased, and the G:F 
      was greater ( < 0.05) in pigs fed diets containing FFRB than in pigs fed diets 
      containing DFRB. The concentration of BUN linearly decreased ( < 0.05) when pigs 
      were fed diets containing increasing levels of FFRB or DFRB. There was a tendency 
      for the concentrations of TNF-alpha and PYY to linearly decrease ( = 0.09 and = 
      0.075, respectively) as the inclusion of FFRB increased in the diet. In 
      conclusion, ADG of weanling pigs was not affected by at least 20% FFRB or DFRB 
      and inclusion of 30% DFRB had no effect on the G:F whereas 30% FFRB increased the 
      G:F. However, microbial xylanase did not influence growth performance under the 
      conditions of this experiment and there was minimal influence of rice coproducts 
      or xylanase on blood characteristics.
