A 14-day continuous intravenous infusion study in rats at 20 mg PGF2 per kg body weight indicated prostaglandins of the F series could induce bone deposition. The metabolism of tritium labeled dinoprost (3H PGF2 alpha) in the rat and in the monkey was similar. Mares: Dinoprost tromethamine was administered to adult mares (weighing 320 to 485 kg; 2 to 20 years old), at the rates of 0, 100, 200, 400, and 800 mg per mare per day for 8days. In turn, LH travels through the blood stream and causes the testicles to synthesize and secrete testosterone. This luteolytic effect can be utilized to control the timing of estrus in estrous cycling and clinically anestrous mares that have a corpus luteum in the following circumstances: For use with FACTREL (gonadorelin injection) Injection to synchronize estrous cycles to allow fixed-time artificial insemination (FTAI) in lactating dairy cows: Administer 2 to 4 mL FACTREL Injection (100-200 mcg gonadorelin) per cow as an intramuscular injection in a treatment regimen with the following framework: Administer the first dose of FACTREL Injection (2-4 mL) at Day 0.

Heart rate, respiration rate, rectal temperature, and sweating were measured at 0, 0.25, 0.50, 0.75, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0, and 6.0 hr. 2. Ltd. You can induce labor with as little as 1/2 cc of Lutalyse, but most people use 2 ccs IM (which is what we use). Cattle producers can synchronize estrus (heat) to breed fertile females rapidly. Mares usually continue to eat during the period of expression of side effects. Hormonal injection in prepubertal gilts and sows with a combination of eCG and hCG induces rapid follicle growth and estrus in 4 to 5 days. The abortion rates following injection of LUTALYSE Injection increased with increasing doses up to about 25 mg. As examples, the abortion rates, over 7 feedlots on the dose titration study, were 22%, 50%, 71%, 90% and 78% for cattle up to 100 days of gestation when injected IM with LUTALYSE Injection doses of 0,1 (5 mg), 2 (10 mg), 4 (20 mg) and 8 (40 mg) mL, respectively. It's also sometimes used off-label to . Heart rate was increased but pH of the urine was decreased. Cattle. Cattle that abort will abort within 35 days of injection. Estrus normally occurs spontaneously in gilts and mature females that are not pregnant or lactating. No apparent differences were observed between the intramuscular and subcutaneous routes of administration. Mares: The most frequently observed side effects are sweating and decreased rectal temperature. General Management of the Sow and Gilt during Farrowing and Lactation Abortion occurs 1-4 wk after infection, so the abortuses are autolyzed.

Most cattle that recovered in response to LUTALYSE Injection recovered within 14 days after injection. Dinoprost tromethamine is readily absorbed through the skin and can cause abortion and/or bronchiospasms. In cattle, evaluation was made of clinical observations, clinical chemistry, hematology, urinalysis,organ weights, and gross plus microscopic measurements following treatment with various doses up to 250 mg dinoprost administered twice intramuscularly at a 10 day interval or doses of 25 mg administered daily for 10 days. If the cow returns to estrus, breed at the usual time relative to estrus. Data suggest prostaglandins, especially PGEs and PGFs, may be involved in the process of ovulation and gamete transport. 2018 Pipestone Veterinary Services. Use a sterile syringe and needle and make the injection through an area of clean dry skin. Lutalyse Injectable is used in cattle for estrus synchronization, treatment of uterine infections, and induction of abortion; in swine for induction of parturition and in horses f LUTALYSE Injection (5 mg dinoprost/mL) is a sterile solution containing the naturally occurring prostaglandin F2 alpha (dinoprost) as the tromethamine salt. 3. One anaphylactic reaction of several hundred mares treated with LUTALYSE Injection was reported but was not confirmed. Average rectal temperature during the periods of decreased temperature was on the orderof 97.5 to 99.6, with the greatest decreases observed in the 10 mg dose group. Cattle expressing estrus following LUTALYSE Injection are receptive to breeding by a bull. Induction is a procedure used to advance estrus. Revised: September 2021 Do not administer to pregnant cattle, unless abortion is desired. Description Lutalyse Sterile Solution is a natural estrus-synchronization product approved for use in horses.

Prostaglandins, especially PGEs and PGFs, have been shown, in certain species, to 1)increase at time of parturition in amniotic fluid, maternal placenta, myometrium, and blood, 2)stimulate myometrial activity, and 3)to induce either abortion or parturition. Non-steroidal anti-inflammatory drugs may inhibit prostaglandin synthesis; therefore this class of drugs should not be administered concurrently. ****Oral/Water Soluble Vaccines for Swine, ***Products for Farrowing and Breeding Swine, ***Swine Ear Tags, Marking, & Identification Products. All systems associated with dinoprost metabolism exist in the body; therefore, no new metabolic, transport, excretory, binding or other systems need be established by the body to metabolize injected dinoprost. Managers using prostaglandins in this manner must use caution. Thus, dinoprost had a safety factor of at least 10X on injection (25 mg luteolytic dose vs. 250 mg safe dose), based on studies conducted with cattle. Keep out of the reach of children. He says he likes the drug because it induces sows more calmly and predictably but Lutalyse is also a choice for inducing females. Store at controlled room temperature 20 to 25C (68 to 77F).

JavaScript seems to be disabled in your browser. These data support previous reports that dinoprost has a half-life of minutes. However, induction of parturition or abortion with any exogenous compound may precipitate dystocia, fetal death, retained placenta and/or metritis, especially at latter stages of gestation. Dinoprost tromethamine is readily absorbed through the skin and can cause abortion and/or bronchiospasms. Summary. Treatment of such mares with LUTALYSE Injection usually results in regression of the corpus luteum followed by estrus and/or ovulation. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. For Treatment of Pyometra (chronic endometritis) in Cattle. Neither heart rate nor respiration rates were significantly altered (P > 0.05) when compared to contemporary control values. The percent of pregnant cattle in each feedlot less than 100 days of gestation ranged between 26 and 84; 80% or more of the pregnant cattle were less than 150 days of gestation. Veterinarians are often asked to induce parturition or they may recommend induction based on the mare's foaling history or the presence of medical conditions that threaten her health and well being. Use only sterile needles, and use each needle only once. Swine: LUTALYSE Sterile Solution will induce parturition in swine at 10 mg (2 mL) when injected intramuscularly. To induce sows and gilts to.

User Safety: Not for human use. Use contents within 12 weeks of first vial puncture. Mares did not appear to sustain adverse effects following termination of the side effects. No vial stopper should be entered more than 20 times. The Lutalyse will only work if there is a corpus luteum which takes about 2 weeks after breeding to form. Metabolism: A number of metabolism studies have been done in laboratory animals. Mares should return to estrus in ~3 days and ovulate an average of 8-10 days after PGF 2 treatment. No mortality occurred in any of the groups. In the early stages, women may be unaware of their pregnancies. Other reactions seen have been increase in heart rate, increase in respiration rate, some abdominal discomfort, locomotor incoordination, and lying down. Lutalyse is the only prostaglandin injection approved for concurrent use with Eazi-Breed CIDR Cattle Inserts in dairy heifers and dairy cows. If given to a pregnant cow, it may cause abortion; the dose required for abortion varies considerably with the stage of gestation. 4. Refer to extra-label drug use. Prick the injection site with your finger two or three times before injecting the needle so as not to startle the sow and cause her to jump up. LUTALYSE Injection is indicated for parturition induction in swine when injected within 3days of normal predicted farrowing. Prostaglandins, especially PGEs and PGFs, have been shown, in certain species, to 1) increase at time of parturition in amniotic fluid, maternal placenta, myometrium, and blood, 2) stimulate myometrial activity, and 3) to induce either abortion or parturition. 5. Day 7 1cc cystorelin. days 5 and 50 of gestation, give 1-2 mLs (5-10 mg). Many factors contribute to success and failure of reproduction management, and these factors are important also when time of breeding is to be regulated with LUTALYSE Injection. Inject a dose of 25 mg intramuscularly. Women of childbearing age, asthmatics, and persons with bronchial and other respiratory problems should exercise extreme caution when handling this product. Since Lute does not directly cause ovulation, a gonadotropin hormone may also be needed to resolve cysts and trigger ovulation. In this post we leave you some practical advice published in pig 333 to induce heat in gilts and sows that you can carry out in your centers. Changes were detected in all treated groups for clinical (reduced sensitivity to pain; locomotor incoordination; hypergastromotility; sweating; hyperthermia; labored respiration), blood chemistry (elevated cholesterol, total bilirubin, LDH, and glucose), and hematology (decreased eosinophils; increased hemoglobin, hematocrit, and erythrocytes) measurements. This can be employed to control the time of farrowing in sows and gilts in late gestation. LUTALYSE Injection (5 mg dinoprost/mL) is a sterile solution containing the naturally occurring prostaglandin F 2 alpha (dinoprost) as the tromethamine salt. Do not administer to pregnant cattle, unless abortion is desired. Using bulls to breed large numbers of cattle in heat following LUTALYSE Injection will require proper management of bulls and cattle. General Biologic Activity: Prostaglandins occur in nearly all mammalian tissues. Cattle must be ready to breed-they must have a corpus luteum and be healthy; b. Nutritional status must be adequate as this has a direct effect on conception and the initiation of estrus in heifers or return of estrous cycles in cows following calving; c. Physical facilities must be adequate to allow cattle handling without being detrimental to the animal; d. Estrus must be detected accurately if timed Al is not employed; A successful breeding program can employ LUTALYSE Injection effectively, but a poorly managed breeding program will continue to be poor when LUTALYSE Injection is employed unless other management deficiencies are remedied first. Store at controlled room temperature 20 to 25C (68 to 77F). The injection of prostaglandin causes any cows with a corpus luteum present on one of their ovaries to regress, ceasing progesterone production. Administer LUTALYSE (25 mg dinoprost, as dinoprost tromethamine) Injection by intramuscular injection 6-8 days after the first dose of FACTREL Injection. When used as part of a synchronized breeding program, Lutalyse helps improve pregnancy rates, reduce cull rates and reduce time for heat detection, and supports more efficient use of labor. Prostaglandin lyses the CL which induces estrus 2-3 days later. At luteolytic doses, dinoprost had no effect on progeny. Whether or not it is fertile is another story. CV (Allows files .doc, .pdf and .odt up to 3MB). Dinoprost was non-teratogenic in rats when administered orally at 1.25, 3.2, 10.0 and 20.0 mg dinoprost/kg/day from day 6th-15th of gestation or when administered subcutaneously at 0.5 and 1.0 mg/ kg/day on gestation days 6, 7 and 8 or 9, 10 and 11 or 12, 13 and 14. In male swine, as in other mammals, GnRH is secreted from the brain and binds to receptors on the anterior pituitary gland, ultimately causing the release of luteinizing hormone (LH). The excessive hyperstimulation of the gastrointestinal tract caused a protracted diarrhea, slight electrolyte imbalance (decreased sodium and potassium), dehydration, gastrointestinal irritation, and slight liver malfunction (elevated SGOT, SGPT at 800 mg only). Sweating after the 5.0 mg dose was intermediate between that seen for mares treated with 3.0 and 10.0 mg. Sweating began within 15 minutes after injection and ceased by 45 to 60 minutes after injection. Updated: 2023-02-28. For example a 2.5 mg dose induces farrowing in 55 h while a 20 mg dose induces farrowing in 28 h. Effectiveness also improves as due date gets closer. Do not use in horses intended for human consumption. With the two injections cattle can be bred after the second injection either at the usual time relative to detected estrus or at about 80 hours after the second injection of LUTALYSE Injection. Prostaglandins, especially PGF2, have been shown to 1) increase in the uterus and blood to levels similar to levels achieved by exogenous administration which elicited luteolysis, 2) be capable of crossing from the uterine vein to the ovarian artery (sheep), 3) be related to IUD induced luteal regression (sheep), and 4) be capable of regressing the corpus luteum of most mammalian species studied to date. Return to normal was defined as evacuation of fluid and return of the uterine horn size to 40mm or less based on palpation per rectum at 14 and 28 days. Breed cows as they are detected in estrus. If estrus has not been observed by 80 hours after injection, breed at 80 hours. Hormonal injection in prepubertal gilts and sows with a combination also induces rapid follicle growth and estrus in 4 to 5 days. Inject a dose of 5mL LUTALYSE Injection (25 mg dinoprost) intramuscularly. Accidental spillage on the skin should be washed off immediately with soap and water. Perform FTAI 0 to 24 hours after the second dose of FACTREL Injection, or inseminate cows on detected estrus using standard herd practices. Mares usually continue to eat during the period of expression of side effects. However, such bone changes were not observed in monkeys similarly administered LUTALYSE Injection at 15 mg dinoprost per kg body weight for 14 days. Do not administer to sows and/or gilts prior to 3 days of normal predicted farrowing as an increased number of stillbirths and postnatal mortality may result. For Unobserved (Silent) Estrus in Lactating Dairy Cows with a Corpus Luteum. Heat detection and insemination of animals in heat on Days 1 to 5. Administer LUTALYSE (25 mg dinoprost, as dinoprost tromethamine) Injection by intramuscular injection 6-8 days after the first dose of FACTREL Injection. Observe animals for signs of estrus on Days 2 to 5 after removal of the EAZI-BREED CIDR Cattle Insert and inseminate animals found in estrus following normal herd practices. The need to induce a mare, and the chances of foal survival should be based on objective measures. Lutalyse is the brand name for dinoprost tromethamine, a sterile solution used for several cattle, swine and mare birthing & birth-related medical conditions. PG 600 comes as a fluid and a powder, and you have to use a needle and syringe to mix the two before use. Have her bred on this heat. Inject a dose of 5 mL LUTALYSE Injection (25 mg dinoprost) intramuscularly either once or twice at a 10 to 12 day interval. All systems associated with dinoprost metabolism exist in the body; therefore, no new metabolic, transport, excretory, binding or other systems need be established by the body to metabolize injected dinoprost. When deciding if it appropriate to abort heifers, you should consider that the chance of complications greatly increases the farther pregnant the heifer is. ESTRUMATE is a prostaglandin analogue that causes regression of the corpus luteum, which results in estrus in two to five days in cycling animals. Evaluate the reproductive status of the mare. Following abortion, early fetal death and resorption, or as a result of pseudopregnancy, there may be serum progesterone levels consistent with a functional corpus luteum. Select one or more newsletters to continue. All Rights Reserved. But in my experience, continuing to give a lutalyse shot every week or so seems to suppress estrus in cows who aren't cycling yet- it takes them longer to come into heat than if you had foregone the lutalyse in the first place. LUTALYSE Injection is indicated for its luteolytic effect in mares. For Treatment of Pyometra (chronic endometritis) in Cattle. If estrus has not been observed by 80 hours after injection, breed at 80 hours. It is important that adequate records be maintained on (1) the average length of gestation period for the animals on a specific location, and (2) the breeding and projected farrowing dates for each animal. Additional studies investigated the effects in the mare of single intramuscular doses of 0, 0.25, 1.0, 2.5, 3.0, 5.0, and 10.0 mg dinoprost tromethamine.
