A protein tub is a very good way to provide extra nutrition when needed. One benefit is that once you have placed it in the pasture you don’t need to check it every day. This is helpful for those that may have a job back in town.
A benefit it can provide for both the full-time and “part-time” rancher is that a protein tub can be used to improve the overall grazing in a pasture. You can move them in to more underutilized areas to encourage cattle to move to those areas.
With making any type of investment it is prudent that you do your homework before you make any decision. So before you go running off to the local feed store I have 5 things that you can look at before you buy your first protein tub.
Step #1: Do I even need a protein tub?
This may seem like a pretty “duh” question to most of us but there are some people out there that do not even consider if they even need it before they buy one. So before you have dropped a nice chunk of change you will need to figure out if a protein tub is even needed.
A good way to determine if supplements are needed is by doing a forage analysis. This will tell you what types of nutrients and in what quantities your forages are providing.
The overall quality of your forages is another factor that you should look at. Like currently here in Texas we have been pretty dry for most of the year so using a protein tub would be necessary. So along with forage analysis looking at the shear amount that you have is another good idea.
Once you have determined what amounts of nutrition are being provided by your forages then you should look at the nutritional needs of your cattle. The stage of production your cattle are in will determine what they will need. An example of this is a cow in late gestation will have completely different needs than a dry one.
Once you have all of this information then it is time for you to do a little math work. You will take what is being provided and what the nutritional needs are, if there is a deficit then you will need to provide a supplement.
Step#2: What does the protein cost per lbs?
A problem that most people follow is that they do not really use an accurate way of comparison. In order to get an accurate comparison, you will need to break it down per lbs. One product may seem like it is more expensive but when you break it down to a cost per unit of what you are needing it can turn out to be cheaper than the other.
A formula that you can use to determine this is like what I used in a previous post “What is that Hay bale worth?”. I will use the formula to determine the cost per unit of protein but you can use it to find other things.
A benefit with protein tubs is that due to their manufacturing they are very very low in moisture so you won’t necessarily have to find out what the unit per dry matter. A formula that can use is this:
Cost of the protein tub / % Protein= Cost per unit of protein
When you have the numbers from the formula then you can more accurately compare “apples to apples”.
Step#3: Where do the minerals come from?
The source of the minerals is also important to look at when looking at protein tubs. Where the minerals come from will determine how well they will be absorbed when it is consumed.
A usual comparison that you will find is chelated vs non-chelated minerals.
Chelated
- bound to a chelated agent, typically organic compounds or amino acids
- tend to be more expensive
- can be recognized by the terms “proteinate or amino acid chelate”
- allow for better absorption and utilization
Non-chelated
- Can be identified by the term “oxide”, “chloride”, or “sulfate”
- tend to be less expensive (which makes it the most common choice with feed producers)
- Not as well absorbed as chelated, especially with animals under stressful conditions
- a more common type of mineral that you will find
Step#4: Will the protein tub have IGR?
Depending on the type of year when you are providing a protein tub you may need to have one with IGR. What this acronym stands for is Insect growth regulator and is used to control flies around your cattle.
When the cattle consume the supplement with this additive it doesn’t affect the cattle in any way so they will pass it along in the manure. While it is there flies will place eggs in the manure and as the larvae grow the IGR chemical will prevent the larvae from getting past a certain stage.
When it comes to using IGR in your protein tubs timing is of the utmost importance. What is recommended is to start feeding it 30 days before the emergence of the flies. This is usually in early spring when the temperatures start to get in the 60s. An example is here in Texas which means usually in the middle of March.
Once you have started feeding this you will need to keep feeding the IGR through most of the year. In order to be most effective, you will keep providing it till 30 days after the 1st frost of the year.
Step#5: What size tub do I need?
Now that you have done the “math homework” and have come to the decision that you will need to use protein tubs for your place. Now you will need to determine how large of a tub you will need.
A lot of this comes down to simply the number of cattle that you are going to be supplementing. Also, the size of the cattle also plays a role in this decision.
A general rule of thumb is that you will need to have 1 tub per 25 heads of cattle. Now, this is not a hard and fast rule but will need to look at the consumption rates.
Another thing to look at is what kind of equipment that will be able to use. Protein tubs range from around 40lbs. all the way up to close to 250lbs. If you do not have say a tractor or skid steer to move the tubs around it may be a better choice to go with the lighter ones (unless you want to ruin your back).
