Lutalyse is an Rx item, so you need a vet prescription to get it. Cattle: 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. This was due to the expected luteolytic properties of the drug. One anaphylactic reaction of several hundred mares treated with LUTALYSE Sterile Solution was reported but was not confirmed. Mares: The most frequently observed side effects are sweating and decreased rectal temperature. 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. I'm also assuming that it has been a month since the breeding happened. Induced abortion may be desired during a normal or abnormal pregnancy. With the single injection, cattle should be bred at the usual time relative to estrus. At these doses, kidding may be expected in 30 to 36 hours. Kid Care LUTALYSE is effective only in those cattle having a corpus luteum, i.e., those which ovulated at least five days prior to treatment. Mares usually continue to eat during the period of expression of side effects. Data suggest prostaglandins, especially PGE’s and PGF’s, may be involved in the process of ovulation and gamete transport. The abortion rates following injection of LUTALYSE 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 doses of 0, 1 (5 mg), 2 (10 mg), 4 (20 mg) and 8 (40 mg) mL, respectively. Use of this product in excess of the approved dose may result in drug residues. Mares treated with either 400 mg or 800 mg exhibited more profound symptoms. According to Goat Medicine, a large dose of lutalyse will help with cervical dilation. For Intramuscular Use for Abortion of Feedlot and Other Non-Lactating Cattle. This information is essential to determine the appropriate time for administration of LUTALYSE.

The mothers both produced plenty of colostrum, and passed their placentas with no issue. Treatment of “anestrous” mares which abort subsequent to 36 days of pregnancy may not result in return to estrus due to presence of functional endometrial cups.

Route of administration for each dose group was both intramuscularly (2 mares) and subcutaneously (2 mares). When necessary, pH was adjusted with sodium hydroxide and/or hydrochloric acid. There was no unequivocal effect of dinoprost on the hematology or clinical chemistry parameters measured. Do not use in horses intended for human consumption. The response to treatment varies by individual animals with a mean interval from administration of 2 mL LUTALYSE (10 mg dinoprost) to parturition of approximately 30 hours. Although Lutalyse will bring a doe into heat, it does not mean that she produced an egg. The product must be administered at a relatively specific time (treatment earlier than 3 days prior to normal predicted farrowing may result in increased piglet mortality). Lutalyse 2cc/adult IM may repeat in 12-14 days Mis-mating (early abortion); not effective at estrus synchronization Epinephrine 1cc/100lbs IM/SQ single dose Anaphylactic reactions to vaccinations, etc; may aid in relaxation of cervix during … An interesting observation in the above study was that the radioactive dose of 3H PGF2 alpha rapidly distributed in tissues and dissipated in tissues with almost the same curve as it did in the serum. Federal law restricts this drug to use by or on the order of a licensed veterinarian.For intramuscular use for estrus synchronization, treatment of unobserved (silent) estrus and pyometra (chronic endometritis) in cattle; for abortion of feedlot and other non-lactating cattle; for parturition induction in swine; and for controlling the timing of estrus in estrous cycling mares and clinically anestrous mares that have a corpus luteum. Goats but not sheep can be induced with prostaglandin (10 mg of Lutalyse®) and kidding or abortion typically occurs in 30 to 36 hours.

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. Cattle/horses: Indicated for its luteolytic effect. Cattle expressing estrus following LUTALYSE are receptive to breeding by a bull. LUTALYSE is indicated for its abortifacient effect in feedlot and other non-lactating cattle during the first 100 days of gestation. So, what’s the moral here?

I recently had the bright idea to call my vet and ask what the lutalyse dose for goats should be. A number of metabolism studies have been done in laboratory animals. Sweating after the 5.0 mg dose was intermediate between that seen for mares treated with 3.0 and 10.0 mg.

These side effects are transitory, lasting from 10 minutes to 3 hours, and were not detrimental to the health of the animal. 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).

Laboratory Animals: Dinoprost was non-teratogenic in rats when administered orally at 1.25, 3.2, 10.0 and 20.0 mg/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. Thus, the 100 mg dose gave a safety margin of 10 to 20X for a single injection or 80 to 160X for the 8 daily injections. Controlling Time of Estrus of Estrous Cycling Mares: Mares treated with LUTALYSE during diestrus (4 or more days after ovulation) will return to estrus within 2 to 4 days in most cases and ovulate 8 to 12 days after treatment. Some of these factors are: a. Because progesterone is necessary throughout gestation for maintenance of pregnancy, PGF-induced death of the corpus luteum leads to termination of pregnancy.

So the dose was effective in 12-15 cases out of 15. I was beginning to be concerned that the same thing was happening this year. Pigs: Induces parturition (farrowing) w/in 3 days of the normal predicted farrowing date. Animal Safety Warnings: Severe localized clostridial infections associated with injection of LUTALYSE have been reported. Mares: LUTALYSE Sterile Solution is ineffective when administered prior to day-5 after ovulation. Prostaglandin F 2alpha (PGF, Lutalyse(R), dinoprost tromethamine) is a hormone that induces luteolysis in many species, including dogs. Should we all start inducing our goats? The metabolism of tritium labeled dinoprost (3H PGF2 alpha) in the rat and in the monkey was similar. If a doe is only 123 days instead of 144 days (i.e., bred the next estrus cycle) the induction will result in abortion or poorly viable kids. Dinoprost tromethamine is a white or slightly off-white crystalline powder that is readily soluble in water at room temperature in concentrations to at least 200 mg/mL.
