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 sows estrus at the same time, induction of estrus, ovarian and uterine disease treatment and other aspects. -
1. Sow induced labour -
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.
Second, for aphrodisiac -
1. Gilts are not in heat at least 8 months old, intramuscular injection of chloroprostol 0.2mg, 3 to 4 days of estrus can be mated.
2, after the sow weaning is not in heat, to the first sow is more common, injection of chloroprostol (0.4 ~ 0.5 mg), in 4 ~ 6d estrus, it is recommended that the estrus temporarily do not breed, and then 18 ~ 21d 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 1 injection 112 days during pregnancy and 1 injection of cloprostenol on the 2nd day after childbirth to achieve satisfactory results, which can not only induce littering, prevent uteritis, vaginitis, but also promote 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, we use 2 sticks of chloroprostol (0.4 mg) 2 to 3 days to give birth to stillbirths, mummified fetuses, dry cadavers and so on.
Fourth, the treatment of hysteritis, uterine empyema -
Intramuscular injection of 1.5 to 2 (0.3 to 0.4 rag) of chloroprostol can discharge uterine effusion and accumulate pus for 24-48 h.
When using this drug, be sure to keep the pregnancy period accurate, so as not to cause premature birth or miscarriage. 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. The effect is true when used for inducing labor, and when it is used for the treatment of hysteritis and uterine empyema, the variety and frequency of medication are reduced, and the trouble of irrigation and intrauterine medication is avoided.
