Ultrasound Nets Most Producers More Than $20/Sow Annually!


How is this possible?

Most producers who implement the use of Real-Time Ultrasound (RTU) experience a reduction of 5-10 Non-Productive Sow Days (NPSDs)/Sow/Year. This is primarily due to the increased accuracy in detecting pregnancy with RTU when compared to using an A-mode scanner. A-mode ultrasound scanners will give you a verbal signal "(beep, beep") when fluid is detected, but that certainly does not guarantee your sow is pregnant! This propensity for "false positive" readings using an A-mode scanner leave most producers generating accuracy rates of 90-95%. In comparison, use of the EZ Preg Checker will typically produce accuracy rates of 98-99% when used 20+ days post-breeding.

The net gain of $20/sow annually has two components. The first is the operational cost of housing and feeding the sow. Most producers have a firm grasp of what this cost is in their operation. It will certainly vary based on location and size, but the most recent numbers we've been hearing from our customers are from $1.75-$2.50/NPSD. (We use $2/day in our example below). The second component is the "opportunity cost" of a NPSD. That is to say, if she were pregnant you would also have the value of the pigs she would be carrying. This value will vary based on the number of weaned pigs produced/litter and current market prices. In our example below, we use a conservative price of $20/weaned pig and an average of 11.4 weaned pigs/litter. This means an additional value of $2/day would be obtained if the open sow were in fact pregnant ($20x11.4/114 day gestation period).

Conservative Example:

ABC Hog Farm lowers NPSD's by 5/sow annually.
Operational cost per NPSD = $2/day
"Opportunity Cost" per NPSD = $2/day

Therefore the "Net Ultrasound Benefit" (NUB) is $20/sow/day.

What is your NUB?


Enter the actual figures from your farm below to see your personalized NUB.

Step 1: Predicted decrease in NPSD's using RTU

Your NPSD Rate Predicted RTU Decrease
49 or lower 2.5 days
50-54 5 days
55-59 7.5 days
60-64 10 days
65+ 12.5 days

In the box below, enter the number from the above chart which corresponds to your current NPSDs.
If you do not know your current NPSD rate, enter 5 as this is a result achieved or exceeded by over 75% of customers we have tracked using RTU for the first time.

Step 2: Operational Cost per NPSD

In the box below, enter the operational cost per NPSD for your farm.
Average current Operational Cost per NPSD is 2.00.


Step 3:Opportunity Cost per NPSD

To get the Opportunity Cost per NPSD enter the average weaned pigs/litter and the current market value/weaned pig for your farm.
The default values shown here are from the conservative example above.
