I don’t get into, argue, dispute, debate, advise and rarely comment on feeding. IMO it is way too subjective. IMO a lot of comments, not necessarily in this thread but in general, and or advice seems to be more based more on “what is written” and or limited experience, hobby breeders then what is practiced at “commercial” TB farms. We are a “soup to nuts” TB farm. Before the financial collapse a few years ago we were breeding and foaling 30+ mares a year. Not large by Kentucky (a place I lived and worked for 20 years) standards but larger than most. The average stud fee of in foal mares here is around $20,000. Modest in the grand scheme of the TB game. Our biggest “claim to fame” was the dam of this year’s Breeders’ Cup Sprint winner was a resident. We have had 3 of our own “home breds” nominated to the Kentucky Derby, one of which almost made it to the gate. Considering that only around 500 out of 24,000 foals are nominated in any given year not bad for a small operation with very limited “mare power”. So I would like to think we are doing things reasonably well. That being said this how we do things.
We feed 8-12 lbs. at this time of year depending on the mares of what everyone likes to call “garbage”, around here, sweet feed. Though it is not a commercial brand, mixed by a small family owed feed mill. It is a 12-14, oats, cracked corn, protein/fat pellets and just enough molasses to bind/hold things together. In the last “tri” we add 1 lb. of calf mania, if a mare is a little ribby and or the weather has been harsh 1 lb± of Buckeye Ultimate finish, a veggie based fat sublimate. We used to throw Alfalfa as a matter of course because that is what everyone does. But when the financial collapse hit, it hit the horse business even worse. Feed and hay is a very LARGE part of any horse business’s balance sheet. We live in a large “horse area” but also dairy and cattle. Alfalfa became prohibitly expensive so we went with Orchard and or Timothy and not IMO the best to be had. I have no experience with any other type of hay. IMO Orchard and Timothy is easily recognizable, especially first cuttings. Everything turned out just fine. The mares bagged up just as they always had. Their colostrum numbers were no different. The foals thrived and sold as well as could be expected. And most performed beyond expectations on the racetrack.
We throw around 20 lbs. second cutting, of hay (Orchard and or Timothy) once a day to our mares, afternoon feeding only. More in cold harsh weather. There is enough “winter” grass, junk for them to gaze on in between. IMO horses are like people, some are naturally on the chunky/thick side of things and other on the lean side. One just needs to learn what their mare’s “type” is. IMO opinion heavier is better than light. IMO and experience feed programs have become much more complicated then they need to be. I just don’t think it is rocket science. As always each their own.
FWIY this is what we do for a living and what clients pay us to do for them. Clicking on my screen name gives a link to our home page and background. Along with contact information for those who would like to take exception to my comments, Email and or voice. I am not giving “advise” just stating what works for us and the results of provide a pretty good living. It is also based on a number of other “care taking” factors and is also based on our horses in our neck of the woods.
