AB  - Optimisation of diets in cows is essential to achieve the 
  best possible performance from these animals. Here, researchers sought to investigate 
  the effects of diet on ruminal microbial protein degradation and synthesis in 
  cows. Three ruminally fistulated Chinese Yellow heifers were used in a 3x3 Latin 
  square trial to study the kinetics of rumen degradation of corn stover. Three 
  diets were formulated to contain corn plus soybean meal (diet 1), corn plus 
  pig blood meal (diet 2) and wheat plus soybean meal (diet 3). Each heifer was 
  allowed a 30 days adaptation following by a 7 day a rumen evacuation <I>in situ</I> 
  during which rumen content was evacuated 0, 2, 4, 8, 16 or 24 h after feeding. 
  Dry Matter (DM) intakes were similar for all diets. The result of rumen evacuation 
  showed that rumen NH<SUB>3</SUB>-N pooling peaked 8 h after feeding for diets 
  1 and 3. Moreover, rumen Volatile Fatty Acid (VFA) pooling varied depending 
  on DM retention for all 3 diets and rumen DM, Neutral Detergent Fibre (NDF) 
  and Acid Detergent Fibre (ADF) poolings were lowest for diet 1 at 4, 8 and 16 
  h after feeding, respectively (p&lt;0.05). Therefore, diet 1, containing corn 
  plus soybean meal, resulted in low rumen DM, NDF and ADF pooling but high DM, 
  NDF and ADF degradability in the rumen of Chinese Yellow heifers. These results 
  shed light on ruminal processes and will aid in the development of optimal diets 
  in cows.
