Closamectin Treatment Regime

It is recomended that treating beef cattle at least twice a year is the most effective way of controlling the fluke problem on your farm. 

Housing: Cattle should be treated at the time of housing or just after housing. A second treatment may be needed if the cattle are housed early or if the area is highly susceptible to contamination.

Turnout:Cattle should be treated at 8 to 10 weeks after turnout. This treatment will kill fluke that have been picked up by cattle as soon as they were turned out. This treatment will also help reduce the reinfection of pastures. 

Outwintering: For cattle who are outwintered a treatment should be given in the late autumn to early winter, a second treatment may be needed in January/February.

Bought in cattle: All bought in livestock should be treated and quarantined for at least 48 hours, this will help protect your herd from infections introduced from new cattle
