Understanding Equine Reproduction Challenges

Equine reproduction can be a complex and delicate process, but understanding the challenges involved can help horse owners and breeders make informed decisions.

In a typical breeding season, a mare is only fertile for about 5-7 days, making timing crucial for successful conception.

The estrous cycle, which is the mare's reproductive cycle, can be influenced by factors such as age, nutrition, and stress.

A mare's first breeding season, also known as her first estrous cycle, typically occurs between 12 and 18 months of age.

Health issues can arise during equine reproduction, particularly in mares.

Pregnancy toxemia, a life-threatening condition, can occur in late-term pregnant mares.

A mare's nutritional status plays a significant role in preventing pregnancy toxemia, as a lack of energy can lead to the condition.

Semen collected from stallions with sperm accumulation syndrome after a week or more of sexual rest will contain very high numbers of sperm and a majority of the sperm will be dead.

This condition can have significant consequences for breeding programs, as it can lead to reduced fertility and lower conception rates.

Placentitis in mares is a serious health issue that can have devastating consequences for the mare and her unborn foal.

Placentitis is caused by bacterial infection, usually from E. coli or Streptococcus equi, which can lead to inflammation of the placenta and potentially life-threatening complications.

The symptoms of placentitis may include vaginal discharge, bleeding, and a swollen vulva.

If left untreated, placentitis can cause premature birth, abortion, or even death of the mare.

Diagnosing placentitis typically involves a combination of physical examination, ultrasound, and blood tests to detect the presence of infection.

Treatment for placentitis usually involves antibiotics and supportive care, such as fluids and anti-inflammatory medications, to help manage symptoms and prevent complications.

The UC Davis Veterinary Hospital has a dedicated Equine Reproduction Service that provides advanced reproductive care to horses. Faculty and resident veterinarians work together to offer a range of services.

Routine and advanced reproductive care is available for mares, including diagnostic work-ups, artificial insemination, and ultrasonographic pregnancy diagnosis. They also help with twin reduction, pregnant mare care, and obstetrics.

Foaling management is another area of expertise, with clinicians working closely with veterinarians specializing in surgery, neonatology, and critical patient care. They also manage mares experiencing dystocia, or difficult foaling.

For stallions, fertility evaluation and investigation of infertility are available, along with breeding management and semen collection and evaluation. They can also prepare and ship cooled semen and freeze semen for future use.

Advanced reproductive technologies, such as transvaginal aspiration of oocytes, ICSI, embryo transfer, and collection and freezing of epididymal sperm, are also offered.

At the Center for Equine Health, you can access a team of experts in equine reproduction, including a board-certified veterinary specialist and a veterinary technician. They offer a range of services to help with reproductive needs, from mare breeding management to stallion semen collection and processing.

Mare breeding management is a key area of focus, with services including pregnancy evaluations, early twin reduction, and mare infertility evaluations. These services are essential for ensuring the health and well-being of both mare and foal.

A unique aspect of the Center for Equine Health is its ability to offer advanced equine assisted reproduction techniques, including intracytoplasmic sperm injection (ICSI). This complex procedure involves technical skills that are typically not offered by veterinary practices.

The ICSI technique has been successful in producing healthy foals from valuable mares, and it's now a routine procedure at several centers in the US, Europe, and Australia. This cutting-edge technology is a testament to the expertise and innovation of the equine reproduction team.

Here are some of the key services offered by the Center for Equine Health:

Protecting equine reproduction through biosecurity is crucial to prevent the spread of disease among horses.

The Equine Reproduction Laboratory is a great resource for learning about strategies for preventing disease spread.

Stable strategies, such as those developed at the lab, are essential for maintaining a safe and healthy environment for horses.

These strategies can help prevent the spread of disease and ensure the health of the horses.

At the lab, scientists work to develop and test effective biosecurity measures to protect equine reproduction.
