Good Supplements For Moody Broodmares

It's no secret that some broodmares can get cranky. Often, this is not just their personality. It is indicative of some pain during ovulation or of some bigger underlying hormonal imbalance. Although it is always a good idea to have your vet check over any moody broodmares, you may also want to consider using one or more of the following horse supplements for breeders to help ease their moodiness between breedings.

Devil's Claw

Devil's claw is an herb that is known for its pain-relieving qualities. However, it is easier on the kidneys and the digestive tract than bute. It can be a big help for mares whose moodiness is due to uterine cramping or similar discomfort during their cycles. It is thought to work, in part, by reducing inflammation, which is involved in a lot of mares' reproductive pain. Most devil's claw supplements for horses come in a powdered or pelleted form and can be added to the top of the daily feed ration.

Valerian Root

Valerian root is another herb that is good for alleviating any uterine pain or inflammation that may be making your mares cranky. It not only alleviates inflammation but also muscle spasms, which means it can really help to combat cramping. Valerian root is also thought to have a calming effect, so it is a good choice to give to mares who get a little excited or hard to handle when they are in heat or preparing to be bred.

St. John's Wort

St. John's Wort is known for its antidepressant effects. It can be a good choice for mares whose moodiness seems to flare up after weaning or when their foals are taken away. St. John's Wort is also said to help boost fertility, which is certainly not a bad thing in a broodmare. 


Poppy seeds have pain-relieving qualities, which makes them a good choice for mares who have some pain and discomfort with their heat cycles. It is also a sedative, which means it can help calm very frisky mares down. You may not want to give poppy seeds consistently because their sedative effect is so pronounced. Instead, just keep this supplement on hand and give it to your mares for a few days if they start acting moody.

You can also find some supplements formulated for moody mares that contain several or even all of the above ingredients. They can be life-changing when you have moody broodmares in your breeding barn.
