Parasite control in beef herds

Fleckvieh-cows pregnant in the 7th month were either treated with IVOMEC Pouron (0,5 mg Ivermectin / kg btw.) or administered the Paratect Flex bolus (active agent: Moranteltartrat for cattle), After calving, cows and calves were turned out on pasture, Despite a low worm burden, as judged by the coproscopic findings, calves showed clear differences in body weight gain: calves of cows treated with IVOMEC Pour-on had gained more weight than their mates of cows treated with the Paratect Flex bolus, The farmer had at sate a surplus of about DM 100, - for each male weanling of the Pour-on group. The different weight gin is attributed to the different antiparasitic efficacy of the drugs used.
