TI  - Dietary fiber for dogs: II. Iso-total dietary fiber (TDF) additions of divergent 
      fiber sources to dog diets and their effects on nutrient intake, digestibility, 
      metabolizable energy and digesta mean retention time.
PG  - 4229-35
AB  - The objectives of this study were to examine widely divergent fiber sources for 
      their efficacy as ingredients in a meat-based dog diet and to determine the 
      effects of these fibers on fecal excretion responses and mean retention time of 
      marked fiber in the gastrointestinal tract of the dog. Fiber sources tested 
      included beet pulp (BP), tomato pomace (TP), peanut hulls (PH), wheat bran (WB) 
      and alkaline hydrogen peroxide-treated wheat straw (AHPWS). Diets were 
      isonitrogenous (5.3% N) and iso-total dietary fiber (TDF; 12.5%). Thirty female 
      English Pointers (five/treatment) were used in the experiment. Intakes of DM and 
      OM were similar among treatments. The highest intakes of ether extract (EE) 
      occurred on the TP, PH and WB treatments. Dogs fed PH ingested the most crude 
      fiber (23.6 g/d), NDF (53.5 g/d), ADF (34.3 g/d) and TDF (59.7 g/d). 
      Digestibilities of DM and OM for all fiber treatments were lower than the control 
      (87.6 vs 81.8% for DM; 90.2 vs 85.4% for OM), but values were similar among fiber 
      sources. The highest EE and N digestibilities occurred on the control and AHPWS 
      treatments. No differences were noted among exogenous fiber-containing treatments 
      in fiber component digestibility. Digestible energy and ME values generally were 
      similar among treatments. Among fiber sources, BP resulted in the greatest amount 
      of wet feces excreted (270 g/d) and the lowest fecal DM (30.3%). No differences 
      among fiber sources were noted in frequency of defecation or mean retention time. 
      Iso-TDF diets (containing, on average, 12.5% TDF) appear to be utilized 
      similarly, regardless of the diversity in sources of fiber tested.
