http://www.gvequine.net/Pages/articles26.html Most people agree that it is safest to feed beet pulp that has been well soaked in order to avoid esophageal obstruction (choke). During the cooler months, soaking beet pulp before feeding is usually not a huge issue, as we do not have to worry about spoilage. In the summer, however, it should be soaked for only a short amount of time, because once it sours it will not entice any horse’s palate. http://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/hrs3243#soaked Myth: "Beet pulp must be soaked before you feed it." "If you don't soak beet pulp before feeding it, it'll swell up and rupture the horse's stomach." "Beet pulp will swell up in your horse's esophagus and cause choke if you don't soak it first." These are just a couple of the diabolical warnings surrounding the feeding of beet pulp. Because beet pulp seems to "grow" when water is added, somebody surmised that it could be a hazard if fed dry because it would absorb saliva and gastric juices, swell up, and block the esophagus or cause the stomach to burst. Although inaccurate, these evil predictions deter many horse owners from even trying beet pulp. Beet pulp may soak up water like a sponge, but it cannot soak up saliva quickly enough to expand in the esophagus and cause choke. Instead, choke associated with beet pulp (particularly the pelleted form) is often in response to the particle size and the horse's aggressive feeding behaviour, rather than the actual feed itself. Horses that bolt their feed without sufficient chewing, or do not have adequate access to water, are far more likely to choke, regardless of the type of feed, compared to horses that eat at a more leisurely rate. Nor is it likely that dry beet pulp will rupture the horse's stomach. The equine stomach holds 2 to 4 gallons. This volume is equivalent to 4.5 to 9.5 pounds of dry beet pulp, which is more than most horses receive in a single meal. Likewise, most food that enters the stomach passes on to the small intestine within 15 minutes or less—and for those of you who have timed how long it takes beet pulp to expand, it's longer than 15 minutes. Assuming free access to water, horses will voluntarily drink enough water to adequately process any amount of beet pulp consumed (1.5 to 2 litres per pound of beet pulp). Along with this drinking water, fluid is constantly entering the digestive tract, so beet pulp will not "suck the horse dry." Ultimately, the 40 to 50 gallon capacity of the equine digestive tract is more than sufficient to contain even a very large meal of beet pulp. The only horse in danger of a gastric rupture is one suffering from impaction or other severe lack of normal peristaltic movement. So, contrary to popular belief, you don't have to soak beet pulp (either the pelleted or shredded form) in water to feed it safely to horses. Research at several universities, including some of my own studies, have fed dry beet pulp in amounts up to 50% of the total diet without choke or other adverse reactions. Likewise, many, many tons of dry beet pulp-based feeds are fed annually without incidence. For example, most commercial feeds designed for geriatric horses contain large amounts of beet pulp and are fed straight out of the bag without being soaked first. If you choose not to soak the beet pulp before feeding it, make sure your horse has access to as much good, clean water as he wants (which should be the case no matter what you feed). Although soaking beet pulp is not necessary, there are several good reasons for wetting it down before you feed it. Soaking beet pulp may make the feed easier to chew, particularly for older horses with bad teeth. Soaked beet pulp may also be more tasty and it provides a useful method for hiding minerals or medications. If your horse gobbles down his feed or is prone to choke, it might be a good idea to soak your beet pulp. And while horses will drink water on their own, pre-soaked beet pulp is a good way to get some water into your horses, particularly in the winter when they may not be as inclined to drink what they need. So, if soaking beet pulp fits into your feeding management, by all means, do it. You don't have to soak beet pulp overnight-most of the expansion takes place within the first 3 to 4 hours. You know it is funny that Beet pulp ALONE has this bad reputation, BUT the MAIN ingredient in almost all SENIOR feed is BEET pulp and people are feeding senior feed DRY daily with no problems. Just because senior feed is in a smaller pellet it does not mean that there is any less risk of choke, it just means that a horse eatting the smaller pellet Can get MORE pellets in their mouth at the same time. http://www.triplecrownfeed.com/senioringredients.php The ingredients of the Triple crown senior feed #1 ingredient is beet pulp http://www.buckeyenutrition.com/equ...iorformula.html #3 ingredient Beet pulp http://www.seminolefeed.com/pdf_files/senior_03.pdf Beet pulp based forage http://www.agwayfeed.com/compare_senior.htm Also main fiber source from beet pulp http://www.lmffeeds.com/lmf_senior_horse.html Beet pulp and Alfalfa http://horse.purinamills.com/produc...uineSenior.html Uses alfalfa as the forage base Did you know that alfalfa pellets can swell to at least 3 times there size also!! Accoprding to a nutritionist in one of the websites. Additonally IF there was a great a danger as people mistakenly believe, there would have already been a lawsuit AND the feed companies would have placed a DO NOT feed dry on the label. As it is my bags give the feeding directions for feeding it dry. Beet pulp has been used for YEARS to feed cattle( both dairy and beef cows), Sheep and goats, and pigs and horses. Beet pulp was also tested as a feed for chickens, but it is not what chickens can properly use as a feed source. Feeding is always a personal choice, I feed beet pulp either way I choose on some days to feed it dry and I choose on some days to soak it.
