Cloprostenol is a sterile aqueous solution containing 0.2 mg (or 0.322 mg) of chloroprostol per stick, which is a synthetic prostaglandin f2α analogue. Chloroprostol is a highly active luteinizing prostaglandin analogue, because of its effect is indeed, low price, easy to use, is widely used in sow estrus at the same time, sow induced estrus, sow ovarian and sow uterine disease treatment and other aspects.
1. It is used for sow induced labor
2 loprostenols with a content of 0.2 rags/stick were given intramuscularly at 112 d of the sow's pregnancy at 12:00 noon, and the sow delivered from 8:00 to 12:00 the next day. Reduced the difficulty of management, improve the survival rate of piglets, and there have been no obvious toxic side effects in the past few years.
2. Used for sow aphrodisiacs
1. Gilts are 8 months old or older without estrus, intramuscular injection of chloroprostol 0.2 mg, 3 to 4 days sow estrus can be mated.
2. After the sow is weaned, it is more common to the first sow, injecting chloroprostenool (0.4 ~ 0.5 mg), the sow in 4 ~ 6 d estrus, it is recommended that the sow estrus temporarily do not breed, and then 18 ~ 21 d to the next natural estrus period when the breeding effect is better. In practical work, we recommend that the practice that has been implemented is to inject once every 112 days of pregnancy in sows, and 1 injection of chloroprostol on the second day after the sow gives birth to achieve satisfactory results, which can not only induce sow littering, prevent sow uteritis, sow vaginitis, but also promote sow lactation.
Third, the treatment of sow delayed labor
Some sows have a gestation period of more than 115 days, or even 120 days without littering, and we give birth to stillbirths, mummy fetuses, dry cadavers and so on when we use 2 (0.4 mg) of 2 to 3 days of chloroprostol.
Fourth, the treatment of sow uteritis, sow uterine empyema
Intramuscular injection of 1.5 to 2 (0.3 to 0.4 rag) of chloroprostol can discharge the uterine effusion and pus of sows for 24-~48 h.
When using this medicine, be sure to keep the pregnancy of the sow in mind, so as not to cause the sow to be premature or miscarried. Prostacol has a lytic effect on the corpus luteum, and its role is to directly control the synthesis of cellular synthesis of the luteinous carcass, selectively contracting into the blood vessels of the corpus luteum, and degenerating the corpus luteum ischemia. In the treatment of sow uteritis, sow uterine empyema reduces the variety and frequency of medication, avoiding the trouble of flushing and intrauterine medication of sows. (Source: Luo Yaohua)
