The time and dosage of deworming of sows can be mated a few days after deworming.

The deworming time of sows is March, June, September and December. Safe insect repellent has ivermectin, ivermectin has powder and injection, powder should be mixed for 5-7 days, 1.5 grams of powder can be used for every 10 kilograms, ivermectin injection, 10 milligrams of avermectin or ivermectin per milliliter, 1.5 milliliters per 50 kilograms, and then subcutaneous injection with a short needle of 1 kilogram. After deworming, the seeds can be mated at an interval of about 5 days.

1. Deworming time and dosage of sows

The main results are as follows: 1. Sows can be dewormed in March, July and November every year. If the parasite infection in pig farms is more serious, then one additional deworming is needed, namely March, June, September and December.

2. When deworming sows, we must avoid lactation, and the time of empty pregnancy is relatively short. In order to facilitate operation, we generally choose to deworming during pregnancy. Now it is generally recognized that ivermectin is a safe and effective deworming drug.

3. There are two kinds of ivermectin powder and injection, the former is given by subcutaneous injection, the latter is given orally by mixing material, and the general injection can be injected once subcutaneously, because after the injection is subcutaneously injected, it is not immediately absorbed by the body. but contact the sustained release effect of drug adjuvants, adhere to a higher blood concentration within a few days, and effectively dispel adults and gradually developing eggs.

4. Ivermectin powder should be mixed for 5-7 days, the effect mechanism is similar, each bag is 5g, containing avermectin or ivermectin 10mg, according to the instructions for each 10kg body weight, 1.5g powder can be used for internal administration.

5. For subcutaneous injection of sows, it is necessary to use a short needle with a length of 12-15mm, not the long needle commonly used by sows, otherwise it will be injected into the deep muscles of sows and directly absorbed by capillaries, which can not achieve the effect of slow-release deworming.

6. General ivermectin injection, containing avermectin or ivermectin 10mg per milliliter, can be subcutaneously injected with 1.5mg per 50kg body weight.

7. Regularly disinfect the breeding pig population, make amitraz or Zhaoling aqueous solution, and then spray the body surface of breeding pigs 3-4 times a year.

8. Regular deworming of sows needs to be arranged in 1-2 weeks before birth, which can effectively prevent sows from directly transmitting parasites to newborn piglets. If there are more parasites in pig farms, they can be dewormed in time, and then transferred to regular deworming after an interval of 1-2 months.

2. Sows can be mated a few days after deworming.

The main results are as follows: 1. Generally, the breeding interval is about 5 days, and the appetite of the breeding sows will decrease, so we should pay attention to reducing the feeding amount appropriately. If the feeding is excessive, it will significantly increase the temperature in the womb of the sows, resulting in a decrease in the survival of fertilized eggs and a reduction in the litter size of the sows.

2. At the same time, feed will be wasted, the cost of breeding will be increased, and attention should be paid to the mating time of sows for the first time, which is generally suitable when sows are in estrus for the third time. If the sows are mated prematurely, it is easy to cause stillbirth, abortion and other adverse phenomena, thus reducing the growth ability of piglets and resulting in poor breeding efficiency.
