      of Gelatinized Starch-Urea.

AB  - Gelatinized starch-urea (Starea, SU) is an effective and economical source of 
      urea for ruminants. Here we assessed the influence of dietary supplementation 
      with gelatinized starch-urea on the diversity of intestinal bacteria in finishing 
      cattle. Fifty steers were randomly allotted to five treatments with diets 
      supplemented with different doses of Starea [0 % (SU0), 8 % (SU8), 16 % (SU16), 
      24 % (SU24), and 32 % (SU32) of urea-N in total nitrogen]. Denaturing gradient 
      gel electrophoresis (DGGE) of 16S rRNA genes was used to examine the effect of 
      dietary supplementation of Starea on intestinal bacterial flora. Shannon-Weaver 
      and Simpson diversity indices consistently showed the lowest bacterial diversity 
      in the SU0 treatment. Increasing doses of Starea increased the diversity up to 
      SU24 after which, diversity decreased. Cluster analysis of 16S rRNA gene DGGE 
      profiles indicates that the intestinal bacterial communities associated with 
      cattle that were not supplemented with Starea in feed differed in composition and 
      structure from those supplemented with Starea. The amount of Starea supplemented 
      in cattle diets influenced the abundance of several key species affiliated with 
      Lachnospiraceae, Ruminococcaceae, Peptostreptococcaceae, Comamonadaceae and 
      Moraxellaceae. These results suggest that Starea influences the composition and 
      structure of intestinal bacteria which may play a role in promoting ruminant 
      health and production performance.
