In January you examine a group of dairy calves which range in age from 2 to 7 months, with a complaint of hair loss and pruritus. The calves are thin and mucous membranes are pale. One has developed bronchopneumonia, and is also febrile and depressed. You do a skin scraping and find the parasite shown in the image, which your technician identifies as Solenopotes sp. The CBC shows the calves to be severely anemic. What treatment recommendation should you now make to the dairy owner?
A- Vaccinate all calves against Mannheimia hemolytica
B- Treat all calves with hematinics
C- Treat all calves with long acting tetracycline
D- Treat all calves for mange
E- Treat all calves for lice
