Application of Cloprostenol in Sows Production

Cloprostenol is a sterile aqueous solution containing 0.2 mg (or 0.322 mg) of cloprostenol, a synthetic prostaglandin F2α analogue. Cloprostenol is a highly active lysosome prostaglandin analogue. Because of its effectiveness, low price, and ease of use, it is widely used in estrus synchronization, induction of estrus, and treatment of ovarian and uterine diseases. -

First, sow induced production -

Two cloprostenols were used at an amount of 0.2 rag/branch. The sows were injected intramuscularly at 12:00 p.m. during the pregnancy and the sows were pupated at 8 p.m. to 12 p.m. on the second day. Reduced the difficulty of management, improved the survival rate of piglets, and no obvious toxic side effects have been observed in the past few years.

Second, for aphrodisiac -

1, gilts more than 8 months of age without estrus, intramuscular injection of cloprostenol 0.2mg, 3 ~ 4d estrus can be mated.

2. The sows do not have estrus after weaning, and the common sows are more common. Chlorprostinol (0.4-0.5 mg) is injected to heat the estrus at 4-6 days. It is recommended that the estrus should not be bred for the first time, and 18 to 21 days later. The effect of breeding is better when the next natural estrus. In practical work, we recommend that the practice has been implemented with a single injection of 112 days during pregnancy and a satisfactory result of the injection of cloprostenol on the 2nd day after delivery. This will not only induce farrowing, but also prevent uterine inflammation and vaginitis. Can promote lactation. -

Third, the treatment of sows late -

Some sows during pregnancy more than 115d, or even 120d no litter, we used cloprostenol 2 (0.4 mg) 2 ~ 3d when the birth of stillbirths, mummy, mesenchymal children.

Fourth, treatment of metritis, uterine empyema -

With cloprostenol from 1.5 to 2 (0.3 to 0.4 rag) intramuscular injection, 24-hour to 48-hour expulsion of uterine effusion and empyema is effective.

When using this medicine, be sure to record your pregnancy so as not to cause premature birth or miscarriage. Prostaglandins have a solubilizing effect on the corpus luteum, and its role is to directly control the synthesis of luteinizing cyles, selectively contracting blood vessels into the corpus luteum, and degrading the corpus luteum ischemic. It is effective when used for induction of labor, and it reduces the variety and frequency of administration of the drug when used for the treatment of metritis and pyometra, and it is not troublesome for washing and intrauterine administration.
