The purpose of medicated bath is to prevent and treat sheep scabies, sheep lice and other ectoparasitic diseases. In areas where sarcoidosis occurs, sheep can be given medicinal baths twice a year. Medicated bath treatment was performed in late summer and early autumn. In winter, sick sheep can choose to rub it locally with liquid medicine when the weather is warm. At present, there are 0. 05% fenthion EC (100 kg water plus 50g fenthion EC), 0.5%~ 1% trichlorfon bath liquid, Mijing, Bao Suli, etc. Drinking water should be used to prepare the liquid medicine, heated to 60℃~70℃, and the temperature of the liquid medicine should be 20℃~30℃ during the medicine bath. Medicinal bath mainly includes pool bath and shower.

(1) In the pool bath method, one person is responsible for pushing the sheep into the pool, and the other person is responsible for taking care of the pool with a bath fork. In case of sheep whose back and head are not infiltrated, soak them in the liquid medicine; When crowding and mutual squeezing occur, they should be pulled apart in time to prevent the liquid medicine from choking into the sheep's lungs or drowning in the pool. Sheep can leave the pool in 2~3 minutes, so they can stay in the square for 5 minutes before being released.

(2) ? Before taking a shower, the shower site should be cleaned for a trial shower. After the machine works normally, the liquid medicine can be prepared according to the specified concentration. When taking a bath, first drive the sheep to the field, start the water pump for spraying, and after 2-3 minutes, they are soaked through? You can turn off the water pump and drive the soaked sheep into the filtrate column, which can be released after 3~5 minutes. If the number of sheep is small, you can use the bath method. This method is a method of bathing the sheep one by one by hand after preparing the liquid medicine in an appropriate basin, jar or cylinder. It must be emphasized that the medicated bath should be carried out in the morning after sunrise in sunny and warm windless weather, so that the wool will dry quickly after medicated bath. Sheep should stop feeding 8 hours before the medicated bath, and drink enough water 2-3 hours before the bath, so as to avoid the sheep being thirsty and drinking the medicinal liquid by mistake. Before the medicated bath, 3~5 sheep with poor physique should be selected for trial bath, and the medicated bath should be organized as planned without poisoning. Bathe the healthy sheep first, and then bathe the sick sheep; Ewes or sheep with trauma who have been pregnant for more than 2 months will not take a bath for the time being. The liquid medicine should soak the whole body, especially the head. After the medicated bath, let the sheep rest in the shade 1~2 hours, and then graze. In case of wind and rain, hurry back to the sheepfold as soon as possible to prevent colds. Mother and son should not be gregarious within 2 hours after medicated bath to prevent lamb from sucking milk poisoning. It is better to take a medicated bath 7~ 10 days after shearing, but it is not effective too late or too early. For sheep suffering from scabies, the medicated bath should be repeated every 1~2 weeks after the first medicated bath. If the sheep have a shepherd, they should also take a medicated bath. When taking medicine bath, the staff should wear masks and rubber gloves to prevent poisoning. After the medicinal bath, the liquid medicine should not be dumped at will to prevent animals from being poisoned by eating by mistake, and should be taken out and buried deep underground. ?
