  Effect of oral lessions in Breeders
  
• Reduction in feed consumption. Delay of 6 hrs in feeding / increase in feeding time.
• Lower production.
• Reduction in laying
  Increase of eggs in bed

  Studied Hypothesis:

  Micotoxin T-2 = Not detected!
  
  Líquid MHA, changed to DL-Met. (Powder) = Problem persisted.
  

  Stopped use of bactericide in feed = problem perisisted.
