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.BeefSpring dewormingCow/calf pairsConference paper
