Hard ticks can parasitize vampire parasites in sheep, and sheep infected with parasites can be painful and restless. After the parasite parasitizes a certain amount, because the sheep are only sucked by a large amount of blood by the tick, the sheep will only have a emaciated body and anemia and paralysis. For pregnant sheep, abortion is possible, and for lactating sheep, milk production is also affected.
For a small amount of parasitic hard ticks, it can be removed with forceps. Hard ticks vary widely in size, but can be spotted with the naked eye on closer inspection. Blood-sucking hard ticks such as castor seeds are dark red or reddish-brown; blood-sucking ticks are the size of sesame seeds.
When a hard tick infects a sheep, blood sucking can cause local damage to the sheep, such as tissue edema, bleeding, and skin hypertrophy. There may also be secondary bacterial infections, causing suppuration, swelling, and cellulitis. After the sheep are infected by a large number of ticks, the sheep only develop pernicious anemia, and the toxins secreted by the saliva of the tick may cause the sheep to have neurological symptoms, resulting in tick paralysis. When you notice these symptoms, please consult a veterinarian as soon as possible. The practicing veterinarians of the Animal Husbandry Hall can provide free online consultations to provide farmers with scientific consultation opinions.
Effective drugs for the treatment of steroscopes are avermectin, dimethylpyrimidine, 0.1% malathion, 0.1% neothiophos, 0.05% chlorpyrifos, 0.0015% cypermethrin, 0.003% flufenthrin, etc. Please refer to the instructions and dosage of the drug or consult a local veterinarian.
The classification of hard tick disease varies and the distribution areas are different. Ticks can generally overwinter under stones or in gaps in the ground, and the activity season of each tick varies with different ticks, and ticks are generally active on livestock from late February to mid-November. Sheep are invaded by ticks, mostly in the process of grazing and feeding, and the parasitic site is mainly in the area with insufficient coat.
When deworming sheep, we must not forget to eliminate ticks in the pen. The common method is to spray the enclosure with deworming drugs, especially in the wall crevices and holes, and then plug the wall crevices and holes with cement and lime.
