Abstract

A field study was conducted at three different locations in south central Kansas to determine the effects of Dectomax® (DECTO) or Ivomec PO® (IVO) compared to no treatment (CONT) on the liveweight gain and reproductive performance of beef cow/calf pairs. Across all three locations, no differences occurred among treatments in cow and calf live weight gain, cow body condition, pregnancy rate, or age of fetus (P>.05). Low egg counts suggest that the parasite load was too low for a response to parasite control.
