The test group (DEC) calves showed:

  • 4.6 lb heavier weights at weaning
  • Less feed required per pound of gain
  • Lower cost per LB of gain
  • A decrease in percentage of calves with cryptosporidium at 14 days (P=0.01)


The results of this study showed that feeding Deccox-M in the milk replacer pre-weaning increased average daily gain and feed efficiency, as well as reduced the number of calves with Cyptosporidium Parvum.
