Sheep Lice Treatment Ivermectin

It’s that time of year where everyone begins to prepare for winter and to consider appropriate treatment of the parasitic problems that our stock carry in to housing, namely liver fluke, nematodes and ectoparasites. Of the ectoparasites, pediculosis is the biggest cause for concern in cattle when housed and one of the biggest issues in sheep, second only to scab. Ironically lice infestation, treatment and control are often overlooked by the farmer and the vet leading to heavy challenges with welfare implications and loss of margin.

Ivermectin Sheep Drench is a ready-to-use, free-flowing solution of ivermectin. It is formulated to deliver the recommended dose rate of 0.2 mg ivermectin per 1 kg body weight given orally at a volume of 3.0 mL per 26 lbs body weight.

Types of Lice

Lice are divided in to two functional groups: Chewing lice and sucking lice. The chewing lice have robust round heads and feed on skin and hair debris. Sucking lice have piercing mouthparts and feed on the blood and serous fluid of the host animal. Sheep within the UK are only affected by chewing lice.

The sheep body louse (Bovicola ovis)

Bovicola ovis is most common and disrupts feeding patterns, leads to fleece damage/loss and self-inflicted trauma. Spread occurs from animal to animal by close contact. The slow reproductive capacity of Bovicola ovis results in a gradual build-up of louse numbers over several months. This louse is surprisingly large at around 3mm in length.
