The hypothesis that pregnancy success could be improved in early postpartum ewes by prolonging the lifespan of the corpus luteum via active immunization against prostaglandin F2α (PGF2α) was tested. Further experiments in ewes immunized against PGF2α investigated the effects of exogenous PGF2α on the preovulatory follicle and the effects of PGF2α and oestradiol benzoate on corpus luteum function. Four weeks prepartum, 39 ewes bred to lamb during seasonal anoestrus received either 5 mg PGF2α-ovalbumin conjugate (n = 20; immunized) or ovalbumin (n = 19; control) in Freunds complete adjuvant. Treatments were repeated on day 5 post partum with reagents emulsified in Freunds incomplete adjuvant. On day 17 post partum, ewes received 500 iu pregnant mares serum gonadotrophin (PMSG) and 48 h later 50 μg gonadotrophin-releasing hormone (GnRH). Laparoscopy was performed 36 h after GnRH to assess ovarian activity and ewes with recent ovulations were inseminated into the uterus. No immunized ewes ...

The Garole is a prolific breed of microsheep that possesses the FecB gene, which increases ovulation rate. The purpose of this study was to compare embryo production by multiple ovulation in seven Garole ewes with that in seven normal size, non-prolific Malpura ewes, and assess the influence of the large body size of Awassi crossbred recipient ewes on the birth-weight of Garole lambs. Oestrus was synchronised with two intramuscular injections of 7.5 mg prostaglandin F(2alpha) administered 10 days apart. The donor ewes were superovulated by the use of pregnant mare serum gonadotrophin and follicle-stimulating hormone. The onset and duration of oestrus were similar in both breeds. The Garole donors had higher total mean (se) ovarian responses (15.6 [3.6] v 9.1 [2.3]), ovulation rate (13.6 [3.1] v 8.4 [2.2]) and produced more transferable embryos (6.0 [3.5] v 4.0 [0.9]) than the Malpura donors, but the differences were not statistically significant. The Garole lambs produced by embryo transfer were on
Earlier studies have demonstrated that phenol UDP-glucuronosyltransferase (UGT) activity is up-regulated by pregnant mares serum gonadotropin (PMSG) in rat ovary, but not liver. This phenomenon was investigated in more detail in the present study. Ovaries and livers of immature rats, rats synchronized with respect to their preovulatory and corpus lutealphases by treatment with PMSG, and mature rats hyperstimulated with PMSG were compared. Under all of these conditions, only one immunoreactive band of UGT, shown to be phenol UGT, was detected in the rat ovary. The effects of oestradiol, progesterone and/or human chorionic gonadotropin (hCG) on the level of phenol UGT in immature rat ovary were also examined. Partial up-regulation was caused by progesterone or oestradiol, together with hCG, whereas progesterone or oestradiol alone had no up-regulating effect. Follicle-stimulating hormone also seemed to be required for the up-regulation in ovaries enriched in corpus luteum. The present findings ...
Gonadotropins secreted by the pituitary or the placenta in horses. This term generally refers to the gonadotropins found in the pregnant mare serum, a rich source of equine CHORIONIC GONADOTROPIN; LUTEINIZING HORMONE; and FOLLICLE STIMULATING HORMONE. Unlike that in humans, the equine LUTEINIZING HORMONE, BETA SUBUNIT is identical to the equine choronic gonadotropin, beta. Equine gonadotropins prepared from pregnant mare serum are used in reproductive studies ...

Two commercially available progestogen products for cattle, melengestrol acetate (MGA) and norgestomet (SMB) , were evaluated for their ability to induce synchronized estrus in anovulatory ewes. Seasonally anestrous ewes (n=232; determined by blood serum progesterone concentration) of mixed breeding were randomly assigned within broad age groups to one of seven treatments: 1) control (C); 2) MGA only (OMGA); 3) MGA + zeranol (RMGA); 4) MGA + PG-600 (PMGA; 400 IU pregnant mares serum gonadotropin + 200 IU human chorionic gonadotropin in a 5 mL dose); 5) 5MB only (OSMB); 6) 5MB + zeranol (RSMB); and 7) 5MB + PG-600 (PSMB). Beginning 10 d before breeding, OMGA, RMGA, and PMGA ewes were fed .3 mg MGA/d provided through a mixture of shelled com and a commercially prepared pelleted supplement containing MGA. Concomitantly, OSMB, RSMB, and PSMB ewes were given a 3 mg norgestomet implant inserted subcutaneously on the back of the ear. Immediately preceding initiation of the MGA and 5MB treatments, RMGA ...
The effects of embryo number and incubation volume on the development of mouse embryos were evaluated. The growth rate of two-cell mouse embryos to attached blastocyst stage and the growth rate of blastocysts to early somite stage were assessed after culture in different incubation volumes and embryo densities. Embryos were collected from ICR female mice superovulated with pregnant mare serum gonadotropin and human chorionic gonadotropin and mated by ICR males. In experiment 1, groups of one, five, ten, twenty 2-cell embryos were cultured in 10-, 50-, 500-, 1000-microliter drops of BWW media under mineral oil at 37 degrees C in a humidified atmosphere of 5% CO2 and 95% air. As the incubation volume decreased, significantly ( ...
My soon to be 17 year old pregnant mare now has lots of edema on either side of her belly kinda underneath..it is pitting and has been there for two days, she is 251 days in foal/8 1/2 months. Her udder is fine with no changes, but I am really worried and she is a little stiff in the back legs. Talked to the vet on the phone and he said it should resolve but if it didnt we could put her on anti-inflammatories. Should I be worried about this? This has not been an easy pregnancy with 2 bad reactions to her rhino vaccines which we are no longer giving per vets recommendation. I gave her 1/2 dose of banamine yesterday and today and we are hand walking her...I can still feel the baby kicking and moving but not as much as before it seems..any advice Jos ...

As Horses breeders of horses know, the key to producing a healthy foal is treating mama right, beginning with proper nutrition. Providing she is in good physical condition when she is bred -which she most certainly should be most mares do well on a quality maintenance diet until their third trimester. It is during this stage that most of the foals growth will occur and alterations will need to be made in the mares diet to maintain her condition and promote a healthy foal. In months 9, 10 and 11, a pregnant mares energy needs increase by 11, 13 and 20 percent respectively ...

The purpose of this paper was to assess the effect of supplementation of royal jelly on the morphometry of the genital tract, superovulatory response and embryonic quality in adult rabbits. 36 rabbits were distributed in four groups (G), as follows: G1 (n=9): no supplementation with royal jelly, G2, 3 and 4 (n=9): supplementation with 10, 20 and 40mg/day of royal jelly. The superovulatory protocol consisted in the application of a dose of 40UI of Equine Chorionic Gonadotrophin, followed by a dose of UI of Human Chorionic Gonadotrophin, intramuscularly, 48 hours later, and submitted to natural cover. The animals were euthanasiated and the embryos collected 72 hours after copulation. There was no statistical difference for the analyzed variables (P,0.05). The average weight for the female genital tract was 10.89±0.38g; the average weight of right and left ovaries was 0.28±0.02g and the average gonadosomatic index rate was 0.02±0.0g. The number of total recovered structures was 9.2±1.4. The ...
Definition of multiple ovulation in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is multiple ovulation? Meaning of multiple ovulation as a legal term. What does multiple ovulation mean in law?
A variety of problems can cause swelling at the lowest part of the belly. The most common cause in late pregnancy results from the weight of the pregnancy interfering with the mares circulation, causing fluid to seep out into the tissue planes (edema). It is a more common finding in the last weeks of pregnancy in large mares with very pendulous bellies. Ventral edema in late pregnancy is usually not painful, and will indent and retain its form momentarily if you push your thumb into it. It has the texture of closed-cell foam. Ventral edema usually resolves quickly after a mare foals. Rarely, however, rupture of the abdominal wall can cause excessive swelling here too. WHAT TO DO Assess the horses general health using the Whole Horse Exam on Late-Term Mare (WHE), paying particular attention to the mares attitude and appetite. If the mare appears healthy, then this sign may not be a cause for concern. However, if the mare shows any other signs of illness or abnormalities, contact your vet with ...
... on the efficiency of superovulation in Formosan sambar dose. Hsin-Hung Lin, Chih-Hua Wang, Shann-Ren Kang, Wen-Lin Song, Chin-Hui Tseng, Mu-Jung Cheng, Shyh-Shyan Liu, and Perng-Chih Shen. The aim of this study was to examine the effect of different eCG concentrations on the efficacy of superovulation in Formosan Sambar does. All the does were implanted with CIDR for 12 days and superovulation was induced by intramuscularly injection with different concentrations of eCG at day 10. Embryos were collected by flushing the oviduct through midventral laparotomy at day 4 after mating. Results showed that the corpus luteum (CL) numbers of dose superovulated with 1500 (7.3), 2000 (10.6), 3000 (8.5) IU of eCG were significantly higher than that superovulated with 1000 IU of eCG (3.5). However, the embryo recovery rates of dose superovulated with 1000 (85.7%) and 1500 (62.0%) IU of eCG were significantly higher than those superovulated with 2000 (25.5%) and 3000 ...

Of uncertain origin. Theres a story, not very convincing, that when stuck in such a region of calm with little wind to get them across, sailors threw their cargo of horses overboard to save on rations and to lighten the load. Another conjecture is that the term is derived from Spanish golfo de las yeguas, literally, mares gulf, alluding to the unpredictable nature of the mares. A related term is doldrums, the calm area in an ocean around the equator ...

Maria once brought up the issue to Mike one night. Mike simply brushed the matter aside. He was content being left alone with Maria. He did not feel the need to interact with any strangers. Maria felt otherwise. She suggested the idea of going to their neighbors house one day and knocking on their front door. Mike thought this was a terrible idea. He did not want to intrude on anybodys time. Maria tried convincing him that a friendly greeting is not intrusive.. After much effort, Mike finally budged. He agreed to go meet the neighbors one day. It was that sunny afternoon on a Sunday that Maria remembered Mikes promise. She reminded Mike of the promise he had made. Since they were not doing anything that day, she told him now would be a good time to go meet the neighbors.. Mike had completely forgotten about the conversation and let out a reluctant groan. "Do we have to, Maria? How about we do it next week?" he said. "No, we could do it today, right now," she replied. Maria went to the bedroom ...
Here are some of the things that you probably do not know about HCG drops. This diet product comes from a hormone, a bodily hormone from females. High amounts of this hormone are secreted in the body when the female is pregnant and its presence is detected through urine test. This is why when a woman suspects that she is pregnant, she undergoes a urine test. It is actually the amount of HCG in her urine that is measured. A few drops of urine are…. Continue reading » ...
