Suspected Lack of Expected Efficacy reported by clinic on 12 Jan 2016. A producer treated approximately 900 head of feeder cattle with Saber Pour-On insecticide in the fall of 2015 (sometime in Nov 2015). Producer reported that now some of the cattle are scratching, with hair loss, indicating a possible lice infestation. Producer concerned that product is not working for control of lice. The producer is going to re-treat cattle on 14 and 15 Jan 2016. The vet will visit farm and exam cattle to confirm diagnosis. He will send photos of affected cattle and confirm numbers affected and dates of initial treatment. Follow-up pending.Follow-up, 14 Jan 2016: On 14 Jan 2016, the vet visited the farm and examined the animals that had been previously treated with Saber Pour-On insecticide. He confirmed that ~10% of the cattle had hair loss in areas typically associated with lice infestation. He also examined a few animals closely, and in areas of hair loss found both nits and live adult lice. The vet confirmed that the cattle entered the feedlot between the 1st week of November and the second week of Dec, 2015. At that time the cattle weighed ~ 600 700 lbs and were treated on arrival with 15 mL of Saber Pour-On insecticide as part of their processing protocol. No more information is expected.
