Let’s start with the ewe ultrasound. Many ranches are now using animal ultrasound machines, mainly because it is fast and accurate, and can reduce the time of ineffective feeding. Zum Beispiel, Schwangerschaft, previously may have to wait for the ewe belly to see, now more than 20 days after breeding can be found out, a lot more efficient. But how long it takes to measure a sheep depends on the operating process, the performance of the equipment and the cooperation of the team.
Theoretical velocity
Skilled people use ultrasound to measure ewes, if the process is smooth, the detection time of a single sheep can be controlled in 30 seconds to 1 minute. Zum Beispiel, the equipment is adjusted in advance, and the sheep is fixed in advance, at this time, you only need to put the probe in place, scan the image, and judge the result, and the whole process can indeed be very fast. The theoretical limit is even one or two sheep per minute. But this is only the ideal situation, and there are all kinds of problems. Zum Beispiel, if the probe is not positioned, it may be necessary to adjust the position repeatedly, or the sheep does not cooperate with the movement, which will slow down the speed.
The performance of the equipment is also critical. Now some wireless portable ultrasound machines, such as a product from Boxiang, weigh only 200 grams, flexible to use, but also can see the image of the phone. This kind of equipment does not drag the line, the operation of the interference is less, the efficiency is naturally higher. Außerdem, high-frequency probes (such as 5-8MHz) are fast in imaging, but require more precise operation; The low-frequency probe (3.5Mhz), although a little lower resolution, is simpler to use and suitable for novices.
Actual influencing factor
In practice, most of the time is spent fixing the sheep. If the sheep is not secured, struggles or moves, the detection time is doubled. Data show that this step alone can account for more than 50% of the total time. Zum Beispiel, free-range farmers operate a person, but also according to the sheep and take equipment, an hour may only check 20-30, on average, each sheep to spend 2-3 minutes. Aber, if it is a large-scale ranch, the sheep are fixed in advance with a special guarantee frame or limit fence, and the sheep with a high degree of cooperation can check 60-80 per hour, with an average of less than one minute.
The inspection time varies depending on the item. If it is just to confirm that the ewe is not pregnant, skilled people can do it in 20-40 seconds; But if you want to count how many lambs are pregnant, or to see the development of the fetus, you have to carefully scan the different positions of the uterus, and the time may be stretched to 1-3 minutes. In this case, the clarity of the device is important, and the high-resolution ultrasound can recognize the structure of the fetus faster, reducing the number of repeated confirmations.
Key to efficiency
Team work is the best way to measure sheep faster. Two or three people working together, one to fix the sheep, one to operate the equipment, and one to record the data, are much more efficient than working alone. Zum Beispiel, if three people cooperate well, it is no problem to check more than 60 per hour, an average of one per minute. Außerdem, the sheep rushed to the Baoding frame in advance to line up next to reduce the time to catch sheep, but also significantly improve the overall speed.
The operator’s experience is also important. Zum Beispiel, knowing the approximate position of the ewe’s uterine horn can quickly find the best scanning Angle; Or when the image is blurred, you can immediately determine whether the probe position is a problem or the equipment parameters need to be adjusted. These details add up and can save a lot of time. Some ranches also regularly train their staff on how to quickly identify key information in ultrasound images, such as pregnancy capsules and fetal heart rates.
Finally, the choice of equipment. Many pastures now tend to use wireless ultrasound machines, mainly to facilitate movement, such as direct detection in the sheep pen, without driving the sheep to a fixed location. Außerdem, the probe is durable and the battery life is long, which is really easy to use. Aber, the price difference of the equipment is quite large, when choosing to balance the performance and budget, don’t look cheap, and the result will be stuck in two days or the image is fuzzy, but the delay.
