Find answers to the 10 most common misconceptions by nutritionists and producers about Soyex.
- Soyex has too much fat
Soyex contains 12% to 13% fat which is approximately 55% the fat level of roasted soybeans. Roasted soybeans have a 2.25 kg feed limit because of the higher fat level. Roasted Soybeans have been fed to cows for over 20 years and with good results. The good production performance is due to the proper use and balancing of the rations with producers knowing what are the limits of this product. Soyex can be fed up to 3.5 kg per cow per day feeding the rumen the same amount of fat as the maximum feeding rate of roasted soybeans. Soyex does not have too much fat but rather enough of a fat to protein ratio to improve production and in some cases reproduction. The fat in Soyex brings natural vitamin E and emulsifiers into the feeding program. The second benefit to fat into dairy diets is that many of the reproductive hormones are derived from fat. By feeding more omega type fats which Soyex contains, it’s easier for cows to produce these much needed hormones.
- Soyex doesn’t have enough protein / Soyex can’t be fed as a major protein source.
Over the past 10 years there has been much research completed on the types of proteins and amino acids required by high producing dairy cows. No longer do we just balance for bypass, soluble and degradable proteins but rather various degradability of protein pools and how they match the carbohydrate pools. Feed passage rates combine with determines the best type of protein structure needed. Compared to many other feed ingredients Soyex at 42.5% crude protein is a high protein feed. Compare Soyex protein level against canola 36%, corn gluten feed 21%, distillers 26% and roasted soybeans at 39%.
Soyex can be fed as a major protein source to your dairy cows. Typical Soyex inclusion rates are 2-2.5kg/lactating cow/day and 1.5-2.5kg/dry cow/day generally replacing 80-100% of externally purchased proteins. How much external protein can be replaced will depend on your operation’s nutrition, cost, and production goals. Soyex is not limited to lactating rations, but can be included in dry cow, heifer, calf and veal rations too!
- Soyex is too high in soluble protein.
Depending on the amount and quality of forages fed and the feed passage through the rumen will determine the amount of Soyex that can be fed. To date there has not been a ration that could not use Soyex to replace at least 50% of the purchased protein requirement.
- Soyex isn’t high enough in bypass protein.
Strictly considering the level of bypass protein in a feed is older way of looking at protein in rations. Many companies have invested into bypass technology and as long as producers buy this technology over improved ration modeling technology the companies maintain higher profits. This does not mean there is no use for these products just less requirements for bypass protein than previously believed.
- Soyex isn’t heat treated enough. (i.e. idea that complete trypsin inhibitor deactivation (lower urease activity) is necessary for cows/ruminants, misconception that higher bypass is always better)
Unlike roasted beans and heat treated soybean meal, Soyex is unique because it is expeller or cold-pressed. With less heat exposure, Soyex is able to retain most of the natural nutrients and vitamins found in soybeans.
Soyex is not recommended for non-ruminants such as poultry or hogs due to the presence of trypsin-inhibitors, which restricts the absorption of protein. Trypsin-inhibitors are not an issue for ruminants, like dairy cows. Soyex has urease present in the soybean meal due to the lower levels of heat treatment. This urease will limit the amount of urea that can be fed to dairy cows. However, if a non-protein nitrogen source is required, there are several coated types that can be used.
- Soyex will depress butter fat
Rumen environment is often the initial consideration when troubleshooting milk fat depression and, more specifically, the fermentable carbohydrates in the diet and their potential effect on the rumen environment. Low rumen pH can indeed impact the rumen environment and also increase the risk for milk fat depression, but this is just the tip of the iceberg. Management and nutritional decisions that can affect the rumen environment encompass a variety of sources, ranging from the total ration to individual ingredients, facilities and cow factors.
When examining diet and individual ingredients, consider everything from diet formulation and mixing uniformity to quality of fermented feeds, carbohydrate sources, physically effective fibre and, the over feeding of, unsaturated fatty acid sources which includes Soyex. A successful ration keeps all ingredients in balance and don’t over or under feed any nutrients that might decrease the effectiveness of the rumen environment.Facilities and cow factors that should be reviewed include anything that may impact sorting, feed intake patterns, cow comfort, cooling, stocking density and water intake.Milk fat can be depressed in cows as a result of insufficient dietary energy intake, especially during early lactation. Cows in good flesh during the early lactation have a higher milk fat % than cows that enter lactation in thin condition. Most high producing cows lose weight during this interval; therefore, energy intake should be maintained as high as possible without causing the cows to go off feed. When the loss in body fat is too rapid, ketosis can occur. Soyex will not depress butterfat if fed in a well-balanced ration.
- Soyex isn’t palatable
Soyex is a very palatable feedstuff and may be used as a major protein supplement in rations for dairy cattle. Cows love Soyex and will readily clean up the pelleted feed. Soyex is mechanically extruded and fresh, making it just as palatable as the other ‘beany flavoured’ roasted beans and other soy products. Being pelleted makes it even easier for cows to consume and it can readily be mixed or used in top dress rations or robotic feeders to attract cows.
- Soyex won’t keep
Soyex like many other feed ingredients are best fed fresh. Assuming the soybeans were pressed below 14% moisture and stored properly (cool, dry place away from direct light) the shelf life of this product should be two months. Since Soyex has 12% to 13% fat it is not recommended to keep in a hot humid bin for more than a month in the summer time, just as a precaution to the fat going rancid. The advantage to cold-pressed Soyex is the remaining energy that contains a high level of natural vitamin E, antioxidents, and amino acids. This is an advantage for the cow and it increases the shelf life of the Soyex itself. Think of the Vitamin E as a natural antioxidant, beef producers have been adding high levels of Vitamin E to the finishing rations to extend the shelf life of beef cuts in the stores. Soyex is pelleted as it comes out of the system, which enables moisture from the recently processed meal to effectively escape. Soyex requires no special cooling or air drying bins and does not self-heat or rot as is typical with presses that produce a flake-type meal.
None of the above storage concerns producers who have an Energrow System since the Soyex is made daily or weekly and freshness is always at its peak.
- Soyex is just raw beans
Soyex is not just raw soybeans. The high pressure from extruding soybeans, even in cold pressing, does create heat and this low level of heat allows for more degradeable and less soluable proteins. More importantly, by extracting 50% of the oil from the beans, Soyex offers more protein than raw beans meaning that they can be fed with less concerns about over feeding energy.
Not only does your Energrow Pressing System make you a quality feed like Soyex, but adds extra value to your raw beans by extracting oil.
- My nutritionist says Soyex won't work
Soyex is a feed ingredient. Like any other feed ingredient it will work better in some rations than in others due to the other feed ingredients made available. Soyex is very palatable and fresh so your cows will love it. All feed ingredients need to be balanced in the ration properly in order to be effective. Soyex can be fed at 1.5 to 3.5 kg per cow per day in properly balanced rations.
Water is one of the most important nutrients for all living things from plants to humans. However, too much water can cause a person or animal to drown and die. Does this mean water won’t work in your feeding program? To maximize the value of your ration, it is important that you work with an experienced and properly trained nutritionist who is open to trying new products and is not just out to sell their own line of feeds. We would be happy to refer you to a nutritionist that has worked with Soyex before so you can get a second opinion about what Soyex can do for your ration.
Energrow and its supporting team of nutritionists have worked with many dairy producers. In each case, producers buy a system based on it being an economical decision backed by good nutrition.Soyex works. Energrow will review your ration or work with your current nutritionist to see if it is right for you!
