Nutrizorb helps ranchers get more out of less. Today we'll be visiting a little bit about the results of a study we conducted a few years back for Rhyzogreen Nutrition. Nutrizorb is a product active ingredient that you folks incorporate in mineral. The requests that in essence came from Rhyzogreen to consider what physiologically in the rumen this product could be doing. So we, I remember we went back and forth on determining what get the greatest bang for your buck in terms of the research investment in this with our eyes at monetizing the response in a way that cow calf producers could recognize it. What we attempted to do is to look at the in vitro digestion of the hay samples and forage samples and grain samples actually that Duane and Trevor provided to us. So this is about as close as it'll get to Our objective was to determine the effects of feeding Nutrizorb on in vitro through digestibility of two types of products, forages and concentrate samples. The question is, if I'm beginning to feed Nutrizorb and a Riomax product today, will I have an immediate response? Or do they need to incubate that response for X number of days, fourteen days, twenty one days, twenty eight days? If the animal was not adapted, we had a thirty four percent digestibility. After exposing this forage to the adapted rumen fluid, we had a response of thirty seven percent. The next one would be fresh range grass. By exposing this forage to rumen fluid that was properly adapted to real nutrition products, the digestibility increased from fifty six, which is equivalent to a pre lactation diet, to fifty nine a lactation diet. We gained three points. Those numbers are not very large, three points. But they mean a very significant impact in terms of energy response by these cows. For forages that have fallen to sixty five percent, that really is an amazingly good forage. That type of forage had no response. Going back to what we do as cow calf operators, we work in the range of about forty five to fifty five percent TDN. So we should expect that Riomax products should have a positive effect on digestibility based on these in vitro results. The average of the three concentrates we use when we expose those concentrates to fluid that was not adapted, the response was eighty four percent digestibility. When we exposed it to rumen fluid that was adapted, we went up to eighty eight percent digestibility. Whether it's forages or concentrates, the response has been from three to four percentage units improvements in digestibility, which I find extremely interesting. Corn digestibility improved from ninety four point five to ninety seven point seven, silage from sixty nine point five to seventy two point eight, and distillers from eighty nine point one to ninety two point nine. About three to four percentage units improvement in digestibility by exposing this to rumen fluid that's been treated with Riomax products. Increased in digestibility of forages and concentrates of about four percentage units. If you don't want to be talking digestibility, it's a lot harder to say than TDN. The same thing. It's a measure of energy in cow herds. If I look at what our prices locally are, and this may differ a lot from where you're at, a fifty six percent energy corn I'm sorry, hay sales rep for a dollar a one hundred and three dollars and seventy nine cents per ton. At fifty eight point nine, that hay will increase the price at one hundred and twenty six zero three. So that's a differential of twenty two point two five dollars per ton, which translates to about a cent zero point one per pound. If we're going to feed twenty seven pounds of dry matter, or approximately thirty two pounds, we multiply thirty two by zero point zero one one one, and the breakeven proposition is zero three six dollars per cow per day. That means is I can go to the hay auction pay at one hundred and twenty six versus one hundred and three or the equivalent of thirty six cents more per cow per day. Or I can turn around, talk to Trevor, Dave, Dwayne and say, hey, you drop off some of that orange tubs. And can you do that for less than thirty six cents per cow per day? Pre calving quality hay supplemented with Nutrizorb will increase in value upwards of twenty dollars per ton. On a ninety day feeding program, we're looking at thirty dollars per cow for that time period. The benefits of the formula opportunity to meet requirements with very low quality forages and being able to spend less, put an additive in and come back with a greater response. Now that only speaks about the energy concentration improving. This has no evaluation of the mineral response such as has been suggested by many of your customers that there are some additional responses on reproductive performance, you know, days to be pregnant after calving, etcetera, etcetera. So just looking at it from a cost savings, this should decrease the overall cow feed costs in the winter, as long as we see those differentials in hay price. And I'll be honest with you, I've been around a long time. Hay fluctuates a little bit, but I don't think I'll ever see it back at sixty dollars a ton. I said to him, Alfredo, how do you sum how would you sum that up in one sentence? And he looked at me with a funny look on his face like, what a dumb question from from you. He didn't say it, but I could tell he was thinking it. And he says, yeah, I can sum that up in one sentence. And he thought for a while and he said, or Nutrizorb helps ranchers get more out of less.
The Science Behind 15-30% Hay Savings
In this recorded Zoom presentation, Alfredo DiCostanzo, PhD (Professor & Extension Animal Scientist) breaks down research conducted for Rio Nutrition on Nutrizorb, a key component in Riomax tubs.
The study looked at how Nutrizorb impacts rumen function and digestion, and why improving forage digestibility can translate into real-world results — including the potential for 15–30% hay and forage savings in winter feeding programs.
If you’re looking for the “why” behind the Riomax digestion package, this is the science-based explanation.
