Lice infestations and mange mite infections cause significant skin irritation and welfare compromise in cattle, particularly in winter housing.
Lice and mange cause significant chronic discomfort in affected cattle. Pruritic cattle rub against fixtures, show disrupted resting behavior, and lose body condition. Severe infestations cause skin damage and secondary infections. Animals with heavy lice burdens may show restlessness, reduced feed intake, and increased aggression. Mange is potentially transmissible to cattle workers. Treating affected animals promptly and addressing the source of infestation through appropriate management during housing prevents welfare deterioration. Refugia-based approaches are increasingly used to prevent resistance while maintaining efficacy.
