There is a drug used to supress heat called Regumate but you'd have to speak to your vet to see if it was suitable for your horse
No it is not. Regumate is designed for mares. It is used to help prevent them from coming into season by 'adjusting' the levels of certain female hormones. Since a colt is a male it will not affect him in the same way and may cause problems with his hormones. Further more you would need a equine vet prescription for the drug and they would not prescribe it for a colt.
Please separate the mares from the stallion.
The primary hormone used to maintain pregnancy in older mares is progesterone or the synthetic version of it, regumate/altrenogest. This product is used to great effect in preventing EOD (early embryonic death)and a subsequent return to heat due to prostiglandin release due to illness, injury, inflammation etc. especially when pregnancy is being maintained by the primary CL alone. Can be used with anti-inflammitory drugs during transport or when injections that may cause inflammation are required for mares that have to be moved during the early stages of pregnancy. Can be used in late stage pregnancy in conjunction with antibiotic therapy for mares with certain types of low grade infections to insure the foal reaches full term although foal may be dismature, premature septic at birth. Some farms have mares on progesterone therapy as a safeguard. Oxytocin, Prostiglandins can be used to help with the foaling process, milk let down etc.
