Recoverying embryos from very cloudy flushes is always an uncertainty about the pregnancy result. Embryos recovered from very cloudy lavage can even cause an infection to the recipient mare, which will lead to an economic loss to the embryo transfer facility and donor's owner. We started treating our embryos recovered from problem mares and noticed better pregnancy results. Most of the time they are not recovered from mares with uterine infection, since all mares that have bacterial infection are treated prior breeding. Many times, mares can have an inflamatory response to the breeding which can lead to an accumulation of inflamatory fluid in the uterus what can result in low grade's embryos. Below you have
Looking better than ever!!!
Magic Mystery debuts with great success. We are very proud of the results he acquired in Scottsdale 2015. With very little training he proved that he can do great in the show ring. Like his dad, he likes to be in the spotlight. Looking forward to further shows!!!
Sometimes when a Grade 3 - 4 embryo is flushed, you wonder if it should or should not be transferred or shipped. We know that it is difficult to make the decision to transfer an embryo into a good recipient mare, when there is doubt on whether or not the transfer will result in a pregnancy. We advise our clients that ship embryos to us, to leave these types of embryos in a holding media that has the right pH and correct osmolarity for a couple of hours and then re-check the quality of it to make the decision on whether or not transfer. Sometimes, we leave the embryo in media for 12 to 20 hours, depending on just how low-quality the embryo is. Unfortunately, the medias that are available on the market today, do not assist low grade
The results of the study below indicate that exercising mares associated with an increase in rectal temperature after the dynamics of estrous cycle. In summary, significantly fewer embryos were recovered at the time of uterine flushing of exercised mares. Of those embryos recovered, greater proportions from exercised mares were of a poorer quality grade. Ovarian folliculogenesis also appeared to be effected by exercise, as evidenced by the exercised mares having ovulations from smaller diameter follicles, with a significant delay in time to ovulation after PGF2 treatment.

Twinning is an undesirable condition in the mare. If twins are note reduced to singletons at an early stage of gestation, the usual outcome is late-term abortion; few twins are carried to term and survive. Complications that can arise with late-term abortion of twins or delivery of twins at term include dystocia, retained placenta, delayed uterine involution, metritis and death of one or both twins, including death of the mare. Virtually all twins arise from double ovulations, meaning the twins are dizygotic. As one would suspect, the incidence of twin conceptions varies with breed, being more common in breeds with a higher incidence of twin ovulations (e.g., Thoroughbreds have the highest incidence of multiple
Early examination of the placenta provides the clinician with valuable and potentially life-saving information for the foal and mare. It should never be ignored in any foaling. The responsible for foaling should place the unwashed placenta carefully into a plastic bag immediately it is passed and store it in a cool place (not a freezer) until examination. The placenta should be examined within 12-24 hours; usually this will conveniently coincide with the primary (2–6 hours) examination or the second routine examination of the foal (at 24 hours). Step 1: Prepare by appropriate dress with protective coveralls, gloves and boots Remember that the placenta
Colostrum Keep in mind how important is feeding the newborn with colostrum. Make sure to always have an extra bag of colostrum in case you have foals to born in your property. It is probably impossible, or at least it is unwise, to consider immune processes of the neonatal foal without references to the importance of colostral/passive immunity. The most impostant single factor in the humoral immunity process in the newborn foal is the transfer of passive immunity via the colostrum. What is colostrum? Colostrum is a complex of electrolytes, carbohydrates, fats and proteins. - Mammary development in the mare accelerates in the last 2 weeks of pregnancy, during which there are
The Newborn Foal The changes that the newborn foal must make at birth are very profound, involving almost all the body systems. The transition from a fetus that is protected and nourished within the uterus to the free-living neonatal foal is probably the most profound change the foal will have to face. Airway clearance and the establishment of a normal respiratory function are vital. This is integrally coordinated with the cardiovascular adaptations that need to occur. Passage of the foal through the birth canal provides significant beneficial thoracic compression to drive excess fluid from the airway. Foals delivered by cesarean section do not have this mechanism and so need extra care for
A normal foaling, parturation generally occur when the fetus is physiologically ready to survive outside of the mare’s uterus. Preparation of the Mare for Birth A series of brief tasks should be completed at the time of foaling approaches: The vulva must be check for the presence of a Caslick surgery and it should be removed around 14 days prior to the calculated due date. It is recommended that the tail of the mare be wrapped prior to foaling, for cleanliness and also to prevent tail hairs from getting in the way in the event that assistance is required during delivery. Cleaning the perineum and udder of the mare prior to foaling or immediately after foaling may reduce the incidence
The establishment of an embryo sexing technique that is viable to use commercially has become true for us at Zerlotti Equine Reproduction. Taking advantage of many researches done trough our veterinarian colleagues we finally developed one technique that has viable results making us confident enough to offer it to our clients. Just to be clear, this technique is performed at the same day as the flushing day, and the embryo will be transferred already sexed, with no need to perform fetal sexing later on. Here is a simple explanation of the process: - Regular artificial insemination - Ovulation (DAY 0) and synchronization
