What is the hormone responsible for maintaining pregnancy in horses?

What is the hormone responsible for maintaining pregnancy in horses?

Progesterone is one of the key reproductive hormones in the mare. It is the hormone that takes a mare out of heat after ovulation and it is absolutely required for the maintenance of pregnancy.

What are the pregnancy hormones?

Estrogen and progesterone are the chief pregnancy hormones. A woman will produce more estrogen during one pregnancy than throughout her entire life when not pregnant. The increase in estrogen during pregnancy enables the uterus and placenta to: improve vascularization (the formation of blood vessels)

What does Regumate do for mares?

REGU-MATE (altrenogest) Solution 0.22% is indicated to suppress estrus in mares. Suppression of estrus allows for a predictable occurrence of estrus following drug withdrawal. This facilitates the attainment of regular cyclicity during the transition from winter anestrus to the physiological breeding season.

Which method is used to evaluate a mare when she becomes pregnant?

The most accurate method for diagnosis of pregnancy status in the mare is transrectal ultrasonography. Originally, this technique was practical in three situations: early pregnancy diagnosis, early confirmation of nonpregnant mares, and detection of more than one blastocyst.

Why do horses abort?

Bacterial placentitis is by far the most commonly diagnosed cause of abortion in many horse breeding areas. Placentitis is a significant cause of equine late-term abortion, premature delivery, and neonatal death. Except for Leptospira spp and nocardioform infections, most cases of bacterial placentitis are ascending.

Is EIA treatable?

There is no specific treatment available for EIA nor is there a vaccine. Symptomatic and supportive treatments for fever, anemia and weight loss are applied on welfare grounds, at least until a positive diagnosis and the decision for euthanasia are made.

How contagious is EIA?

Equine infectious anemia (EIA) is a noncontagious infectious disease of equids caused by a virus of the same name. It is not known to be transmissible to humans. The principal mode of natural transmission of EIA is on the mouth-parts of blood-feeding insects, especially horse flies and deer flies.

How do you test for EIA?

Agar gel immunodiffusion (AGID). Also known as the Coggins test, AGID is the most widely accepted procedure for the diagnosis of EIA. The test detects antibody against the viral p26 antigen (major core protein). It is the only procedure that has been statistically correlated with the presence of EIA virus in blood.

What causes EIA?

The most common vectors for spreading EIA are biting flies, or tabanids, particularly horseflies. These large blood feeders can carry virus-bearing blood on their mouthparts from an infected horse to others.

How is EIA treated?

Treatment

1. Short-acting beta agonists, which are inhaled drugs that help open airways. These are the most commonly used and generally most effective pre-exercise medications.
2. Ipratropium (Atrovent HFA), an inhaled medication that relaxes the airways and may be effective for some people.

Is there a vaccine for EIA?

There is no treatment or vaccine for EIA, so surviving infected animals must be kept at least 200 yards from non-infected animals until they test negative for EIA.
