Sounds like what my mare needs to get rid of loose stools and get her system going right.
Valerie S on May 21, 2016
I used it for my rescue horse, who doesn't seem to poop as much as he should and doesn't always eat all his hay. Since I've started, he eats more and poops more!

is this pelleted, or powder?
A shopper on Nov 10, 2014
Best Answer: It is a course powder. It mixes well into a grain feed but I put a little water into a pelletted feed so the Opti-Zyme sticks better, otherwise it willl sift to the bottom of the grain bucket.

My 28 year old horse after using opti zyme a couple of days was acting like he was going to colic. After two days off his feed, tonight I only gave him his senior feed without the opti zyme and he ate it. Are there any cases where this product is not appealing to a horse or could it have made him colic mildly?.
A shopper on Mar 8, 2016
Best Answer: I don't know about it giving horses colic. I use it to help my horses digest their food better. I even give extra to my 26 year old who has digestive issues. My vet said to keep all of my horses on it. And my mini and 26 year old had colic issues prior to using Opti-zyme. You should call your vet and ask. As for not liking it, all mine eat it right with there grain but I do make sure to mix it in well. My vet also has me add some water to my seniors grain. Just enough to moisten it for him. I love the product. I also have my guys on pro-bios. I give them the soft chews, one a day. That is also great for digestion issues.
Gotta love our senior babies! Hope you figure it out.

I board my horse an hour from me. If I only feed it to him 3 days a week will it do any good?
Carla D on Oct 15, 2015
Best Answer: Hi, anything is better than nothing. Fortunatly my horse is 50 ft. from my house & I feed this almost every morning. If I don't feed this I give her three to four apples. She had a conpaction a year ago so I have been giving her the mix since. She will deficate 3 to 4 times a night.. I have a mix I use with bran, a cup of rolled oats, opti
zyme, antigest, calf-manna & some apple sauce. My horse loves this mixture and will ask for it after I give her her hay. The main thing you want to achieve is to keep those guts moving. A horse, like us if thier guts aren't moving, they are not feeling well. A horse's intestinal track is very sensitive. Good luck and Happy Trails!!
